WE, ION Water Machineries, one of the pioneer in the field of Water treatment iin West Bengal, Kolkata. We are Manufacturer and supplier of various water treatment equipment such as Iron Removing Plant, Water softening plant. Softener is packed with high polystyrene base resin in sodium form. During service period polystyrene base resin in sodium form adsorb Calcium, Magnesium in raw water and after producing certain amount of soft water these are exhausted. These then require regeneration with 5% to 10% Common Salt solution. In case big units, saturated salt solution is prepared in a R.C.C. tank and require amount of brine is drawn in a brine measuring tank. The brine soln. is then diluted with the help of an injector and fed into Softener.Soft water is then tested with the help of a Hardness Test Kit and fed into different process. In case raw water contains iron more than 0.3 ppm as Fe, an Iron Removal Filter must be installed before a Softener. This is to avoid iron fouling of Ion Exchange Resin in softener.
