We Ion water Machineries manufacturer and supplier of water treatment plants, filters and machinery since 1967 in West Bengal. We manufacturer and supplier of water softening plant for domestic and industrial uses. During service period polystyrene based 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 small capacity 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 water softening unit. In case raw water iron contains more than 0.3ppm as Fe, an iron removal filter must be installed before a softener. This is to avoid iron fouling of ion exchange resin in softener. Capacity 50 to 50000 gallon per hour and above.
