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 exchange sodium ions are relinquished from the resin. Raw water will continue to get softened till the resin gets exhausted. Bringing back 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

Thermic Fluid is the heating media which transfer the heat in close loop cycle. It is available in two forms………. Mineral heat transfer oil. Synthetic heat transfer oil. Mineral oil can withstand maximum temperature up to 280˚C. Synthetic oil can withstand maximum temperature up to 310˚C. Continuous use of thermic fluid systems results in to deteriorating of Thermic fluid. The main causes for deterioration are oxidation & cracking. Oxidation: Oxidation at higher temperatures causes formation of sticky carbon. This causes choking of the system & reduced heat transfer efficiency & also produces acidic products. These add to viscosity of the oil along with increase in corrosion rate at internal parts of thermic fluid heating system.

We offer durable pressure sand filters that are used for the removal of suspended solids & turbidity. The pressure sand filter is extremely robust method of removing suspended solids from water. The filtration medium comprised of multiple layer of sand having different 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.

Ozone is "active oxygen", nature's special element and a beautiful gift to mankind. Ozone is a triatomic allotrope of oxygen formed by recombination of oxygen atoms.

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 Exchange A 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

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 Regeneration Over 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 Systems Ion 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 ions A 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.
