We, ION WATER MACHINERIES, situated at 10, Kiran Sankar Roy Road , Kolkata-700001 one of the pioneers in water treatment industries since 1967 manufacturing various type of water treatment equipment such qs Iron Removing Plant , Arsenic Removing Plant, Water softening Plant etc.Softener is packed with high polystyrene base resin in sodium form. During service period polystyrene base resin in sodium form absorb 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 soln. is then diluted with the help of an injector and fed into the Softener. Soft water then tested with the help of a hardness test kiit and fed into different processes.
