Turn Hard water into Softened water


Water softeners use a cationic resin which primarily removes dissolved positive mineral salts from the water. The predominant salts and minerals targeted are calcium and magnesium. They turn ‘Hard’ water into ‘Softened’ water. Hard water is the cause of scale and lime deposits that form in pipes, plumbing fixtures and kitchen appliances. Hard water also reacts with soap/detergents and causes a scum which reduces the cleaning capability of the product.

Hardness is primarily caused by the dissolved chemical compounds of calcium and magnesium. The amount of hardness is expressed in mg/l.

Water softeners operate on the principle of ion exchange. Hard water containing positively charged calcium and magnesium ions enters the softener and flows through the negatively charged cation resin bed. The positive ions attach themselves to the negative resin (ion exchange) resulting in the treated or ‘softened’ water to flow out and be used as required.

The Water softener is pre-programmed to regenerate when the resin is saturated. During a regeneration, a salt and brine solution flows into the resin tank and cleans the cation resin by removing the attached deposited minerals. The regenerated water is then flushed out the backwash line.
