Sand Filter Carbon Filter

WATER SOFTENER
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

PRESSURE SAND FILTER
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.

ACTIVATED CARBON FILTERS
Activated carbon filters are used for removing free chlorine, phenol, taste and odour as well as reduction COD/ BOD. The specially designed filters are made from FRP closed vessel fitted with multi port valves and are operated under pressure. The water is passed through the under bed media & granular activated carbon layer. These filters have a back flushing arrangement, which easily flushes away the deposited impurity at carbon granules.
Activated carbon filter, for removal of free chlorine, phenol, taste and odour as well as reduction COD / BOD. Granular Activated Carbon is a well establishing & proven technology for the removal of taste, odours and gases from water. It is extremely effective in the removal of many Volatile Organic Compounds (VOC) and other Petroleum-based contaminants.
The Ultra Safe Filters use Granular Activated Carbon, manufactured from hard coconut shell having Iodine content of 900-1000 ppm, whose extraordinary molecular structure adsorbs much more molecules of contaminant molecules that adhere to its surface, through absorption and adsorption.
