We Ion Water Machineries manufacturer, Supplier and seller of Water Softening Plants for domestic and industrial uses for low hardness in raw water. 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 of big units, saturated salt solution is prepared in a R.C.C. tank and required amount of brine is drawn in a brine measuring tank. The brine solution is then diluted with the help of an injector and fed into the softener. In case of medium size softener salt solution is prepared in a salt dilution tank and instantly fed into the softener.In case of small size softener, salt is dumped inside the shell. Excess brine is then drained during the period of rinsing with filtered water. Soft water is then tested with the help of hardness test kit and fed into different processes. A water meter is incorporated on the line for measuring total amount of soft water treated by the softening plant. In case raw water iron contains more than 0.3ppm as Fe, an iron removal filter must be installed before a softening plant. This is to avoid iron fouling of Ion Exchange Resin in softening plant.
