Introduction :-
Softening is a process where Calcium and Magnesium ions are exchanged for Sodium ions. Calcium and Magnesium ions associated with Alkalinity contribute for scale formation. These ions are also called as Total hardness. The strong acid cation ion exchange resin in Sodium form is used for softening the water. When the resin is exhausted, it is regenerated with brine solution ( Sodium Chloride ) 10% or 15% brine solution is normally used for the regeneration. If the brine solution is passed from the bottom of the resin and service flow is from the top, then it is called as Up flow softener. If the service and regeneration flows are from top to bottom, then it is called as down flow softeners. The softeners are run up to the Hardness slip of 5 ppm as CaCO3 in the treated water which is called as Industrial Zero hardness. |

Product Description :-
Industrial Upflow Softeners are manually operated and designed to suite the requirements of medium scale industries. They incorporate the prove technique of counter flow regeneration. The unit thus produce treated water with low residual hardness throughout the cycle.
A strongly acidic cation exchanger in sodium form is used to exchange sodium ions for the hardness forming calcium and magnesium, thus producing soft water. At the end of each service cycle, the ion exchanger is regenerated with sodium chloride solution, after which the unit is ready for the next service cycle.
For introducing the brine into the unit, a hydraulic ejector with control valve, suction and delivery piping are provided. A combined salt tank which can hold sufficient quantity of salt for a number of regeneration is provided.
The unit is supplied in a knocked-down conditions and is easily assembled at site. To meet special requirement, these softeners can be supplied for automatic operation.
Advantages :-
� Consistent treated water quality
� Easy to install and operate
� Produces clear, soft and non-scale forming water
� Low operating costs
� Incorporates high capacity polystyrene bead type cation exchange resin which is remarkably
� stable and has a long life
Applications :-
� Boiler feed
� Process water in textile mills
� Beverage manufacture
� Laundry and air conditioning plants
� Cooling tower make-up
� Jacket cooling
� Bungalows
