Hydropneumatic Pressure Booster System

Leave a comment


Pressure Booster System consists of an automatic pressure controlled pump and a tank, which contains an air filled poly-ether-urethane (PEU) bladder. The water gets pumped in this tank that compresses it and pressurizes the bladder which in turn maintains a desired pressure within the whole water system. This automatic system requires no manual intervention and is built for low maintenance. As the entire home plumbing is kept under pressure by the system it is vital that good standards have been used in water piping and fixtures.

The Pressure Booster System consists of the following components:

  • Water Holding Tank – this tank consists of an air filled bladder. The water enters this tank and compresses the air cell and pressurizes the air, which in turn pressurizes the water. This water is delivered to your water supply system under consistent pressure.
  • A Pump – this pump supplies water to the Water Holding tank and to your water supply system. It is controlled through an automatic pressure controlled switching device.
  • Pressure switch – the pump is electrically connected to the pressure switch, which controls the pressure at which water is delivered.

Features

  • Automatic operation of the system, water under pressure whenever required.
  • Pressure booster system will work in homes with and without the overhead tank. They can replace the overhead tank provided continuous power is available. The composite material (FRP) tank ensures that the vessel never corrodes and no harmful traces of metal (as in steel tanks) pass into your water.
  • The tank is made of Food & Drug Administration (FDA) and National Sanitation Federation (NSF) listed materials, thus environmentally safe and will not introduce any undesirable chemicals or elements.

You need Pressure Booster System if

  • Water trickles from your taps and showers
  • You do not have an overhead tank
  • All floors of your building do not get water with equal force

Benefits

  • Consistent water pressure on all floors.
  • Pressurized full flow shower, which you always wanted.
  • Consistent water flow in bathtubs, dishwashers, showers and garden hose.
  • The modern fittings like mixers require an optimum pressure to function efficiently. Since this pressure is normally not available with an overhead tank, the booster system makes the presence of such fittings more meaningful.
  • Complete and efficient management of water pressure.

As the system is switched on, the pump which is connected to the raw water source, starts pumping water into the hydro-pneumatic booster tank. The pressurized water from the tank is pumped to your water supply system.

When the taps are closed in your supply system, pressure builds in the tank. As the pressure reaches the optimum level, the pump is shut off. When the taps are opened, you get pressurized water from the water holding tank. As the pressure reduces and reaches a certain undesired level, the pump is automatically started. The pressure controlled automatic pump switching device in the system frees you from the problem of switching the pump on and off again.

Hydrp pneumatic booster system is designed either with single or with multiple pumps to have continuous water pressure. Systems are also designed with Variable Frequency Drive Unit.

Various types of Pumps are used for pneumatic booster system depending upon application and use. Booster Tank is used to get smooth operation of the Pump allowing pump to work for minium 1/2 to 1 min.

Ion Exchage Plant

Leave a comment


Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic ‘ion exchangers’.

Typical ion exchangers are ion exchange resins (functionalized porous or gel polymer), zeolites, montmorillonite, clay, and soil humus. Ion exchangers are either cation exchangers that exchange positively charged ions (cations) or anion exchangers that exchange negatively charged ions (anions). There are also amphoteric exchangers that are able to exchange both cations and anions simultaneously. However, the simultaneous exchange of cations and anions can be more efficiently performed in mixed beds that contain a mixture of anion and cation exchange resins, or passing the treated solution through several different ion exchange materials.

Ion exchangers can be unselective or have binding preferences for certain ions or classes of ions, depending on their chemical structure. This can be dependent on the size of the ions, their charge, or their structure. Typical examples of ions that can bind to ion exchangers are:

  • H+ (proton) and OH- (hydroxide)?
  • Single charged monoatomic ions like Na+, K+, or Cl-
  • Double charged monoatomic ions like Ca2+ or Mg2+
  • Polyatomic inorganic ions like SO42- or PO43-
  • Organic bases, usually molecules containing the amino functional group -NR2H+
  • Organic acids, often molecules containing -COO- (carboxylic acid) functional groups
  • Biomolecules which can be ionized: amino acids, peptides, proteins, etc.

Ion exchange is widely used in the food & beverage, hydrometallurgical, metals finishing, chemical & petrochemical, pharmaceutical, sugar & sweeteners, ground & potable water, nuclear, softening & industrial water, semiconductor, power, and a host of other industries.

Most typical example of application is preparation of high purity water for power engineering, electronic and nuclear industries; i.e. polymeric or mineralic insoluble ion exchangers are widely used for water softening, water purification, waterdecontamination, etc.

Ion exchange is a method widely used in household (laundry detergents and water filters) to produce soft water. This is accomplished by exchanging calcium Ca2+ and magnesium Mg2+ cations against Na+ or H+ cations (see water softening).

Ion exchange resins in the form of thin membranes are used in chloralkali process, fuel cells and vanadium redox batteries. Ion exchange can also be used to remove hardness from water by exchanging calcium and magnesium ions for hydrogen and chlorine ions in an ion exchange column.


Water Softening Plant

We call water “hard” if it contains a lot of calcium or magnesium dissolved in it. A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water. These “hardness ions” cause three major kinds of undesired effects.

Most visibly, metal ions react with soaps and calcium-sensitive detergents, hindering their ability to lather and forming a precipitate-the familiar “bathtub ring”. Presence of “hardness ions” also inhibits the cleaning effect of detergent formulations.

Second, calcium and magnesium carbonates tend to precipitate out as hard deposits to the surfaces of pipes and heat exchanger surfaces. This is principally caused by thermal decomposition of bi-carbonate ions but also happens to some extent even in the absence of such ions. The resulting build-up of scale can restrict water flow in pipes. In boilers, the deposits act as an insulation that impairs the flow of heat into water, reducing the heating efficiency and allowing the metal boiler components to overheat. In a pressurized system, this can lead to failure of the boiler.

Third, the presence of ions in an electrolyte, in this case, hard water, can also lead to galvanic corrosion, in which one metal will preferentially corrode when in contact with another type of metal, when both are in contact with an electrolyte. However the sodium (or potassium) ions released during conventional water softening are much more electrolytically active than the calcium or magnesium ions that they replace and galvanic corrosion would be expected to be substantially increased by water softening and not decreased. Similarly if any lead plumbing is in use, softened water is likely to be substantially more plumbo-solvent than hard water

Ion-exchange resin devices
Conventional water-softening devices intended for household use depend on an ion-exchange resin in which “hardness” ions trade places with sodium ions that are electrostatically bound to the anionic functional groups of the polymeric resin. A class of minerals called zeolites also exhibits ion-exchange properties; these minerals were widely used in earlier water softeners. Water softeners may be desirable when the source of water is a well, whether municipal or private.

How it works
The water to be treated passes through a bed of the resin. Negatively-charged resins absorb and bind metal ions, which are positively charged. The resins initially contain univalent hydrogen, sodium or potassium ions, which exchange with divalent calcium and magnesium ions in the water. As the water passes through the resin column, the hardness ions replace the hydrogen, sodium or potassium ions which are released into the water. The “harder” the water, the more hydrogen, sodium or potassium ions are released from the resin and into the water.

Resins are also available to remove carbonate, bi-carbonate and sulphate ions which are absorbed and hydroxyl ions released from the resin. Both types of resin may be provided in a single water softener.

Regeneration
As these resins become loaded with undesirable cations and anions they gradually lose their effectiveness and must be regenerated. If a cationic resin is used (to remove calcium and magnesium ions) then regeneration is usually effected by passing a concentrated brine, usually of sodium chloride or potassium chloride, or hydrochloric acid solution through them.

For anionic resins a solution of sodium or potassium hydroxide (lye) is used. If potassium chloride is used the same exchange process takes place except that potassium is exchanged for the calcium, magnesium and iron instead of sodium. This is a more expensive option and may be unsuited for people on potassium-restricted diets.


DM Plant

Demineralization or Deionization is the process of removing mineral salts from water by using the ion exchange process. With most natural water sources it is possible to use Demineralization and produce water of a higher quality than conventional distillation.

The following ions are widely found in raw waters:

Calcium (Ca2+) Chloride (Cl)
Magnesium (Mg2+) Bicarbonate (HCO3-.)
Sodium (Na+) Nitrate (NO3-)
Potassium (K+) Carbonate (CO32-)
Iron (Fe2+) Sulfate (SO42-)

There are three ways in which ion-exchange technology can be used in water treatment and purification: first, cation-exchange resins alone can be employed to soften water by base exchange; secondly, anion-exchange resins alone can be used for organic scavenging or nitrate removal; and thirdly, combinations of cation-exchange and anion-exchange resins can be used to remove virtually all the ionic impurities present in the feedwater, a process known as deionization. Water deionizers purification process results in water of exceptionally high quality

Shubham manufactures a wide range of custom-built Demineralizing plant for industrial process water applications, with inherent design to conserve water, and save costs. They are available in different sizes and materials, manually operated or fully Automatic, & ready to install & are available as standard models or custom built versions for specific needs.

Operating Principle
Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.

There are four distinct stages in the operation of Deionisers

  • Service
  • Backwashing
  • Regeneration
  • Rinse/remix

Service
In the Service cycle the water enters the vessel and passes through the Resin bed of the respective exchanger.

Backwashing
After the resins are exhausted, the bed is backwashed. Backwashing is carried out by a uniform upward flow of water through the resin bed. The backwash step expands the resin bed releasing any entrapped particulate matter & removes the channeling in the resin column if occurred during the service cycle.

Regeneration
When the ion exchange resins loose all the exchangeable ions, they require regeneration to restore them back to hydrogen or hydroxyl form depending upon whether they are cation or anion resins. To achieve this 4 – 5% concentrated solution of Hydrochloric acid is used for cation resin and a 4% – 5% concentrated solution of caustic soda for anion resin. Sulphuric acid can also be used for Cation Regeneration but the concentration of acid during injection must be kept at minimum, such as to prevent calcium sulphate precipitation on the resin.

Rinse
The final stage of regeneration is to rinse the resins of excess regenerant

Advantages

  • Easy to install & operate
  • Complete Assembly with backwash &regeneration equipment
  • Produces DM water of high purity


Degasifiers

Shubham also offers a range of degassers designed to suit the de-mineralisers.The cation exchanger converts alkalinity present in raw water to its equivalent acid, i.e. Carbonic acid. The anion exchanger absorbs this along with other acids in cation exchanger treated water. Where water has a high alkalinity the ionic load on the anion can be brought down by using another method to remove carbonic acid. The carbon dioxide can be removed mechanically by means of degasser.

A degasser consists essentially of a degasser tower with integral tank, a degasser air blower and a degassed water pump with necessary piping and valves to connect this system to the CA Unit. The tower portion is packed with PVC Pall rings. The air blower is connected by air ducting to the tower just above the tank portion.

Mixed-Bed Deionizers

In mixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained in a single pressure vessel. The thorough mixture of cation-exchangers and anion-exchangers in a single column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant.

Although more efficient in purifying the incoming feedwater, mixed-bed plants are more sensitive to impurities in the water supply and involve a more complicated regeneration process. Mixed-bed deionizers are normally used to ‘polish’ the water to higher levels of purity after it has been initially treated by either a two-bed deionizer or a reverse osmosis unit.

Sewage Treatment Plant

Leave a comment


Waters that are used for drinking, manufacturing, farming, and other purposes by residences (toilets, baths, showers, kitchens, sinks), institutions, hospitals, commercial and industrial establishments are degraded in quality as a result of the introduction of contaminating constituents. Organic wastes, suspended solids, bacteria, nitrates, and phosphates are pollutants that commonly must be removed.

To make wastewater acceptable for reuse or for returning to the environment, the concentration of contaminants must be reduced to a non-harmful level, usually a standard prescribed by the Environmental Protection Agency.

Sewage can be treated close to where it is created (in septic tanks, bio-filters or aerobic treatment systems), or collected and transported via a network of pipes and pump stations to a municipal treatment plant.

Sewage treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. The task of designing and constructing facilities for treating wastewaters falls to environmental engineers. They employ a variety of engineered and natural systems to get the job done, using physical, chemical, biological, and sludge treatment methods. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds.

The features of wastewater treatment systems are determined by (1) the nature of the municipal and industrial wastes that are conveyed to them by sewers, and (2) the amount of treatment required to preserve and/or improve the quality of the receiving bodies of water. Discharges from treatment plants usually are disposed by dilution in rivers, lakes, or estuaries. They also may be used for certain types of irrigation (such as golf courses), transported to lagoons where they are evaporated, or discharged through submarine (underwater) outfalls into the ocean. However, outflows from treatment works must meet effluent standards set by the Environmental Protection Agency to avoid polluting the bodies of water that receive them.

Sewage Treatment Plant is basically characterized as below system based on usage of Oxygen / Air in Secondary Treatment Stage (Biological Decomposition of organic matter).

Aerobic STP
Here Oxygen/Air is continuously supplied to the Biological (Aeration) Reactor either by direct Surface Aeration system using Impellers propelled by Pumps or Submerged Diffused Aeration system using Air Root Blowers for Air supply through diffusers. Aerobic condition leads to complete oxidation of Organic Matter to Carbon Dioxide, Water, Nitrogen etc. thus eliminating Odor problem caused due to incomplete oxidation. Also Air supply aids in uniform and efficient mixing inside the tank.

Anaerobic STP

Here sewage is partially decomposed in closed Biological Reactor in absence of Air which leads to reduction of Organic Matter into Methane, Hydrogen Sulfide, Carbon Dioxide etc. It is widely used to treat wastewater sludge and organic waste because it provides volume and mass reduction of the input material to a large extent.

Conventional Sewage Treatment Plant

Conventional sewage treatment involves three stages, called primary, secondary and tertiary treatment.

First, the solids are separated from the wastewater stream. Then dissolved biological matter is progressively converted into a solid mass by using indigenous, water-borne micro-organisms. Finally, the biological solids are neutralized then disposed of or re-used, and the treated water may be disinfected chemically or physically (for example by lagoons and microfiltration).

The final effluent can be discharged into a stream, river, bay, lagoon or wetland, or it can be used for the irrigation of a golf course, green way or park. If it is sufficiently clean, it can also be used for groundwater recharge or agricultural purposes

Pre-treatment
Pre-treatment removes the materials that can be easily collected from the raw wastewater and disposed of. The typical materials that are removed during pre treatment include fats, oils, and greases (also referred to as FOG), sand, gravels and rocks (also referred to as grit), larger settleable solids and floating materials (such as rags and flushed feminine hygiene products).

Pre treatment also typically includes a sand or grit channel or chamber where the velocity of the incoming wastewater is carefully controlled to allow sand grit and stones to settle, while keeping the majority of the suspended organic material in the water column. Sand, grit, and stones need to be removed early in the process to avoid damage to pumps and other equipment in the remaining treatment stages.

Preliminary treatment processes include coarse screening, medium screening, shredding of solids, flow measuring, pumping, grit removal, and pre-aeration. Chlorination of raw wastewater sometimes is used for odor control and to improve settling characteristics of the solids.

Primary treatment

Sedimentation
In the primary sedimentation stage, sewage flows through large tanks, commonly called “primary clarifiers” or “primary sedimentation tanks”. The tanks are large enough that sludge can settle and floating material such as grease and oils can rise to the surface and be skimmed off. The main purpose of the primary sedimentation stage is to produce both a generally homogeneous liquid capable of being treated biologically and a sludge that can be separately treated or processed. Primary settling tanks are usually equipped with mechanically driven scrapers that continually drive the collected sludge towards a hopper in the base of the tank from where it can be pumped to further sludge treatment stages.

Secondary treatment

Secondary treatment is designed to substantially degrade the biological content of the sewage such as are derived from human waste, food waste, soaps and detergent. The majority of municipal plants treat the settled sewage liquor using aerobic biological processes. For this to be effective, the biota require both oxygen and a substrate on which to live. There are a number of ways in which this is done. In all these methods, the bacteria and protozoa consume biodegradable soluble organic contaminants (e.g. sugars, fats, organic short-chain carbon molecules, etc.) and bind much of the less soluble fractions into floc. Secondary treatment system commonly employs an Aeration Tank wherein microorganism culture completely degrades organic as well as inorganic impurities in the presence of either Surface Aerators or Diffused Aeration system.

Secondary sedimentation
The final step in the secondary treatment stage is to settle out the biological floc or filter material and produce sewage water containing very low levels of organic material and suspended matter.

Tertiary treatment
The purpose of tertiary treatment is to provide a final treatment stage to raise the effluent quality before it is discharged to the receiving environment (sea, river, lake, ground, etc.). More than one tertiary treatment process may be used at any treatment plant. If disinfection is practiced, it is always the final process. It is also called “effluent polishing”.

Packaged Sewage Treatment Plant

There are areas within the cities, towns and villages that are impossible to cover under centralized wastewater treatment system, to offer perfect solution for the same, Shubham steps in this field. Shubham package type wastewater treatment system is compact, effective and economical for wastewater treatment in decentralized manner. PWTS-AM series is ideal for individual bungalows, low rise apartments, restaurants, offices, small factories, etc. NBF series is ideal for malls, hospitals, office building, institutions, townships/colonies, high rise buildings etc.

Operation Principle

1. Solid Separation Zone: This is the primary treatment process that separates solid and scum from wastewater.
2. Aeration Zone: Clear water flows into this stage. Oxygen supplied by air blowers is required for the digestion of bacteria culture thriving in and around the plastic media inside the aeration zone, thus reducing the amount of contaminants while generating more contacts with the bacteria culture on the surface area of media. The quality of water becomes better.
3. Sedimentation Zone: The next step of treatment involves the sedimentation where organic wastes are settled in the sedimentation zone. The settled waste in the bottom of the tank can then be pumped back to the solid separation as a return sludge to ensure that quality of effluent passes the required standard. Chlorine is sometimes introduced before discharging the effluent into public mains.
Advantages
1. 100% Eco friendly
2. Rust Proof
3. Leak Proof
4. Durable Light Weight
5. Easy to Install
6. Massive reduction of BOD

Membrane Sepration And Filter

Leave a comment


The membrane separation process is based on the presence of semi permeable membranes. The principle is quite simple: the membrane acts as a very specific filter that will let water flow through, while it catches suspended solids and other substances.

Membrane filter can be divided up between micro and ultra filter on the one hand and nano filtration and Reverse Osmosis (RO or hyper filter) on the other hand. When membrane filter is used for the removal of larger particles, micro filter and ultra filtration are applied. Because of the open character of the membranes the productivity is high while the pressure differences are low. When salts need to be removed from water, nano filter and Reverse Osmosis are applied. Nano filter and RO membranes do not work according to the principle of pores; separation takes place by diffusion through the membrane. The pressure that is required to perform nano filter and Reverse Osmosis is much higher than the pressure required for micro and ultra filtration, while productivity is much lower.

Reverse Osmosis (RO): Reverse osmosis (RO) is a separation process that uses pressure to force a solvent through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a high dissolve solids concentration through a membrane to a low dissolve solids concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute.

Ultrafiltration (UF): UF is a pressure-driven membrane-based separation process in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.

UF’s main attraction is its ability to purify, separate, and concentrate target macromolecules in continuous systems. UF does this by pressurizing the solution flow. The solvent and other dissolved components that pass through the membrane are known as permeate. The components that do not pass through are known as retentate. Depending on the Molecular Weight Cut off (MWCO) of the membrane used, macromolecules may be purified, separated, or concentrated in either fraction.

Microfiltration (MF): MF is a pressure-driven membrane-based separation process in which particles and dissolved macromolecules larger than 0.1 micrometers are rejected. The retentate typically includes macromolecules and particulates Microfiltration is not fundamentally different from reverse osmosis, ultrafiltration or nanofiltration, except in terms of the size of the molecules it retains.

Nanofiltration: Nanofiltration is a pressure-driven membrane-based separation process in which particles and dissolved molecules smaller than about 2 nm are rejected. As with RO, retentate types include salts and nonpolar solvents.

Micro Filtration

Microfiltration is a filter process which removes contaminants from a fluid (liquid & gas) by passage through a micro porous membrane. A typical microfiltration membrane pore size range is 0.1 to 10 micrometers (µm). Microfiltration is not fundamentally different from reverse osmosis, ultra filtration or nanofiltration, except in terms of the size of the molecules it retains.

Microfiltration membranes remove all bacteria. Only part of the viral contamination is caught up in the process, even though viruses are smaller than the pores of a micro filtration membrane. This is because viruses can attach themselves to bacterial biofilm.

Increasingly used in drinking water treatment, it effectively removes major pathogens and contaminants such as Giardia lamblia cysts, Cryptosporidium oocysts, and large bacteria. For this application the filter has to be rated for 0.2 µm or less. For mineral and drinking water bottlers, the most commonly used format is pleated cartridges usually made from polyethersulfone (PES) media. This media is asymmetric with larger pores being on the outside and smaller pores being on the inside of the filter media.

Micro filter can be implemented in many different water treatment processes when particles with a diameter greater than 0.1 mm need to be removed from a liquid.

Examples of micro filter applications are

  • Cold sterilisation of beverages and pharmaceuticals
  • Clearing of fruit juice, wines and beer
  • Separation of bacteria from water (biological wastewater treatment)
  • Effluent treatment
  • Separation of oil/ water emulsions
  • Pre-treatment of water for nano filter or Reverse Osmosis
  • Solid-liquid separation for pharmacies or food industries

Water Filtration Plan

Water Media Filter Plant is used in water purification for treating raw water to produce a potable product. They are typically 1 to 2 meters deep, can be rectangular or cylindrical in cross section and are used primarily to treat surface water.

Filter is a process for removing suspended and colloidal impurities from water by passing through porous media. Filter with or without pretreatment has been employed for treatment of water to effective removal of turbidity, suspended particles, colloidal particles, microorganism etc.

Currently there are also some good conditioned media available in the market used for iron and manganese removal.

Depending upon the application and water treatment requirements, filter systems use a variety of media to remove contaminants. Flirtation system can be classified according to …..

1. Direction of Flow
2. Types of Filter media or bed
3. Driving Force
4. The method of flow rate control
5. Filter and Loading Rate

Depending upon the direction of flow through filter, these are designated as…
1. Down flow,
2. Up flow
3. Bi-flow
4. Radial flow
5. Horizontal flow filters.

Based on filter media and bed, filters has been categorized into

1. Pressure Sand filter or mono-media filter
2. Multi media filter
3. Dual media filter
4. Activated Carbon filter
5. Iron Removal Filter
6. Arsenic Removal Filter
7. Screen Filter System

Based on driving force and pressure filter can be.
1. Slow Sand Filter
2. Rapid Sand Filter
3. Pressure Sand Filter

Shubahm provide a wide range of Water Filter Plant for the different applications like Water Pre-treatment, surface water treatment, Tertiary filter, cooling tower side stream filter etc.

Pressure Sand Filter

pressure sand filter consists of a pressure vessel-this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water.

Raw water flows down wards through the filter bed and as the suspended matter- which has usually been treated by addition of a coagulant like alum- is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head as the filter process continues and the flow reduces once the pressure drop across the filter is excessive.

The filter is now taken out of service and cleaning of the filter is effected by flow reversal. To assist in cleaning the bed, the backwash operation is often preceded by air agitation through the under drain system. The process of air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.

Activated carbon Filter

Activated carbon (AC) is a natural material derived from bituminous coal, lignite, wood, coconut shell etc., activated by steam and other means, and each one have different adsorption properties (e.g. bituminous carbon for high chlorine reduction capacity). We also use various blends of carbon to achieve specific water quality and contaminants reduction (e.g. coconut shell carbon for “sweet taste”).
Rapid Gravity Sand Filters
The rapid gravity sand filter is a type of filter commonly used in municipal water treatment facilities. Rapid sand filters use relatively coarse sand and other granular media to remove particles and impurities that have been trapped in a floc through the use of flocculation chemicals – typically salts of aluminium or iron. Water and flocs flows through the filter medium under gravity pressure and the flocculated material are trapped in the sand matrix.

Rapid filters are usually built open with the water passing down the filter but by gravity. It has a filter rate of 4 – 8 m3/m2/hr. The tank is made of concrete with a depth of 3.0 to 3.5m. Coarse sand of size 0.4 to 1.5mm is used as the filter medium.
Screen Filter
A screen filter is a type of filter utilizing a rigid or flexible screen to separate sand and other fine particles out of water for irrigation or other applications. Typical screen materials include stainless steel (Mesh), polypropylene, and nylon.

Side Stream Filters

Side stream Filters normally used for industrial cooling tower. Cooling Towers, by design, flush airborne contamination such as biocides, heat, slime or silt into the system, where they deposit on heat exchange surfaces. Suspended matter in the cooling water also supplies living microorganisms with a constant food source for sustaining life and multiplying. Shubahm provide suitable cooling tower side stream Filter (SSF) which can remove all the physical contamination from the water which affects the life and efficiency of the cooling towers system.

Iron Removal Filter

Operation
Iron removal filter is manually operated, processed catalytic filtration unit where the raw water passes through the layer of compressed air, processed catalyst & quartz filter media respectively. The dissolved ferrous iron salts are converted into insoluble ferric salt and precipitated over the filter bed and then the iron free filtered water comes out. Only backwashing with clear water and compressed air is required for cleaning the bed.

The iron removal filters that we manufacture are widely used to eliminate turbidity, suspended particles, color, odor and iron that are available in raw water. These iron removal filters are known for their easy operation and give crystal clear water. Our iron removal filters are accurately designed to fulfill our client’s specific requirements. These filters purify water from sand without clogging the filter. The entire range can also be customized as specified by the clients.

Horizontal Pressure Sand Filter

Pressure filters typically offer lower initial and operating costs than conventional systems, and the package nature of these systems greatly simplifies the design and installation for the engineer and contractor.

Specifically, pressure filter systems have been developed to focus on common ground water problems like iron, manganese and hardness. For high iron and manganese applications, our pressure filters can be provided with manganese green sand and potassium permanganate feed systems.

Horizontal pressure filters are especially well suited for the high volume flows required by large municipalities, industries, and power utilities. Our unique multi-cell backwash system offers the economy of horizontal pressure filters, without the need for backwash pumps.

We supply different types of filter used for industrial and potable water supply. The filter are being used in potable and advance wastewater treatment plant and other industries.

Working Principle
In pressure sand filter raw water flows down wards through the filter bed and as the suspended matter- which has usually been treated by addition of a coagulant like alum- is retained on the sand surface and between the sand grains immediately below the surface.

There is steady rise in the loss of head as the filter process continues and the flow reduces once the pressure drop across the filter is excessive. The filter is now taken out of service and cleaning of the filter is effected by flow reversal. To assist in cleaning the bed, the backwash operation is often preceded by air agitation through the under drain system. The process of air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.

Shubham offers horizontal pressure filters in diameters up to 12 feet. Different from other pressure filters in the industry; our pressure filters utilize the low head loss under drain and the systematically managed Air System. These unique features reduce backwash head requirements, improve backwash distribution characteristics, and achieve efficient backwash cycles. These features, along with standard instrumentation and control package, simplify design and minimize startup complications.

Our Horizontal Pressure Sand Filters are designed to save on space and cost without compromising performance, durability, or ease of operation. Each tank is manufactured by ASME Code certi?ed welders from Type 316L stainless steel, a material which is specially fashioned to offer superior protection against corrosion in chloride environments. The result is a product that is virtually indestructible and perfectly suited to commercial swimming applications, insuring many years of reliable service.

Our largest standard units have more than 500 square feet of filtering area, and can reliably supply plants that treat from 1 to 25 million gallons per day.

Our horizontal multi-cell designs partition the unit to form individual filter cells. They can often be used as a cost-effective substitute to multiple vertical units.
