Water softener in Coimbatore

By keeping track with the market development, Water softener in Coimbatore is offering optimum quality Water Softener. This system purifies and cleans the water. Water softening is the removal of calcium, magnesium, and certain other metal cations in water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually hard water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. Hard drinking water may have moderate health benefits, but can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of suds formation when soap is agitated in water, and by the formation of lime scale in kettles and water heaters. Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects.

Ion exchange resins are organic polymers containing anionic functional groups to which the divalent cations (Ca++) bind more strongly than monovalent cations (Na+). Inorganic materials called zeolites also exhibit ion-exchange properties. These minerals are also available to remove carbonate, bicarbonate and sulfate ions which are absorbed and hydroxide ions released from the resin. When all the available (Na+) ions have been replaced with calcium or magnesium ions, the resin must be re-charged by eluting the Ca2+ and Mg2+ ions using a solution of sodium chloride or sodium hydroxide depending on the type of resin used for anionic resins, regeneration typically uses a solution of sodium hydroxide or potassium hydroxide .The waste waters eluted from the ion exchange column containing, the most common means for removing water hardness rely on ion- exchange resin or reverse osmosis. Other approaches include precipitation methods and sequestration by the addition of chelating agents.

Conventional water softening appliances intended for household use depend on an ion exchange resin in which “Hardness ions” –mainly Ca2+ and Mg2+ are exchanged for sodium ions. As described by NSF/ANSI standard, ion exchange devices reduce the hardness by replacing magnesium and calcium (Mg2+ and Ca2+) with sodium or potassium ions (Na+ and K+)
