Ion exchange technology is used to remove salts (cations and anions) from the water Soluble chemical compounds, when dissolved in water, become ionized; that is their molecules dissociate into positively and negatively charged components called ions. Consider common table salt, sodium chloride. In its solid form, this compound consists of one sodium atom (Na) and one chlorine atom (Cl) tightly coupled together (NaCl). When dissolved in water, however, the compound splits into two ions, Na and Cl. Ion ExchangeA process in which Contaminant ions are exchanged from water is called ion exchange. This process occurs in ion exchange resin Initially, resin is loaded with hydrogen (H ) ion for cations and hydroxide (OH-) ion for anions. As water passes through the resin, the contaminant ions in the water displace the loaded ions from the sites on the resin. This is because the resin has a greater affinity for the contaminant ions. Affinity for most resins is based loosely on ionic size and charge RegenerationOver a period of time most of the cation resin gets converted into Ca, Mg, Na form and it has no Hydrogen Ions (H ) to replace Ca, Mg, Na ions and the anion resin gets converted into Cl, SO4, SiO2 form and it has no Hydroxyl Ions (OH-) to replace Cl, SO4, SiO2 ions. This is called the resin exhaustion or end of service cycle. The exhausted resin has to be brought back into Hydrogen (H )Hydroxyl (OH-) form to continue the process and use it again and again. The procedure of converting exhausted resin into Hydrogen (H )Hydroxyl (OH-) form is called regeneration Separate Bed DM SystemsIon exchange occurs across at least two different columns. The first is a cation column, which is filled with resin loaded with positive hydrogen ions (H ). As water passes through this column, the positively charged impurities in the water are exchanged for the hydrogen ionsA similar exchange takes place in the second column, the anion column. This column is filled with resin loaded with negative hydroxide ions (OH-). As the now cation-free water from the cation column passes through, any negatively charged contaminants are removed from the water and replaced by hydroxide ions from the resin. The water now has a neutral pH. hydroxide [OH-] and hydrogen [H ] ions exchanged in the columns combine, forming water [H2O) Mixed Bed Systems In a Mixed Bed System water is purified by removing all ions in one pass through an ion exchange bed. The bed consists of cation and anion resins in mixed condition, so that ions are actually removed in the same two step ion exchange process. All the traces of Cations and Anions of the dissolved solids and silica in the water are replaced by Hydrogen ion (H) and Hydroxyl Ion (OH-) respectively. We get very high purity demineralized water at the outlet of the MB.

Weoffer durable pressure sand filters that are used for the removal of suspended solids & turbidity. The pressure sand filter is extremely robust methodofremovingsuspended solids fromwater. The filtration medium comprised of multiple layer of sand havingdifferent size &specific gravity. As per the needs of customers, we can offer sand filters in various sizes and material apart from hand operated or fully automatically, Filter is used for separating water suspended solid for better operation of filter, suspended solid should be coagulated. The advantages of pressure filter are high speed of filtration, less space, low charge and prevent heat loss after the warm or hot lime process. pressure filters, which may be vertical or horizontal, have cylindrical steel shells and dished heads. The flow in pressure filters is downward. Usually sand or anthracite is the filter medium in a bed consisting of either one or two grades of sand or anthracite. A gravel bed supports the filter medium, prevents fine sand or anthracite from passing into the under drain system and distributes backwash water. The water, which should be filtered, enters over the top of filter and pass from its bed then they collected at the bottom of filter. The suspended matter is strained out of the water and held in the voids between the filtering granules. The accumulation load of suspended matter in the bed causes an increasing loss of pressure during the filter run. When this loss reaches a predetermined limit, the filter is backwashed upward, discharging the suspended load out to the sewer.

Activated Carbon is porous from of Carbon manufactured from internal surface area.

The porosity Creates a remarkable power of Adsorption, an indispensable Process in industrial separation.

Purification, decolonization & recovery technique. The Carbon atoms at the internal surface of Activated Carbon.

Exert an attraction ( Vendor waars force ) on the molecules of surrounding liquid & gas & fixes on to its pore walls.

This is the basis of mechanism whereby Activated Carbons may be used to remove one or more components from a mixture.

GRANULES In GASPHASE adsorption, Granular Carbon is almost always used because the Pressure drop in the Carbon bed is of prime importance & Granular Carbon will allow sufficient flow with an acceptable pressure drop.

In LIQUID PHASE application both Granular & powered Carbon can be used .

DUE to SUPERIOR ADSORPTION HIGH DENSITY, LOW ATTRITION LOSS, use of Granules has resuited in increased service life, greater filter efficiency, fewer regeneration cycles & economy on Hardware costs.

Activated Carbon Granuces made from coconut shell charcoal is used when a single product or grade is being continuously treated in large quantities. Normally Granular Carbon can be regenerated which involves washing or burining off the impurities & restoring the pore structure.

Raw Water is termed Hard Water when it contains dissolved salts of Calcium & Magnesium. Temporary alkaline or carbonates of calcium & magnesium, Permanent non alkaline or noncarbonated hardness is caused by dissolved chlorides, sulphates or nitrates of calcium & magnesium, Softener removes hardness in water. Process The softening process consists of passing raw water containing hardness through a bed of cation resin in sodium form. The hardness ions Ca & Mg are taken up by resin and in exchangesodium ions are relinquishedfrom the resin. Raw water will continue to get softened till the resin gets exhausted. Bringingback the resin to it original form is called regeneration. Softener resin is regenerated by sodium chloride (NaCl) of 10 -15% Concentration. Requirement for Designing Softener: Hardness of Water, Flow Rate/Hour, Single Charge Softening. WE OFFER ALL RANGES OF WATER SOFTNER
