Softeners Water softeners may very well be Situated possibly upstream or downstream of disinfectant removal models. They make use of sodium-centered cation-exchange resins to get rid of water-hardness ions, like calcium and magnesium, which could foul or interfere With all the overall performance of downstream processing devices including reverse osmosis membranes, deionization equipment, and distillation units. Water softeners can be made use of to remove other decrease affinity cations, including the ammonium ion, Which may be released from chloramine disinfectants typically Utilized in ingesting water and which could if not carryover through other downstream device operations. If ammonium elimination is among its functions, the softener should be Found downstream from the disinfectant removal Procedure, which by itself may possibly liberate ammonium from neutralized chloramine disinfectants. Water softener resin beds are regenerated with concentrated sodium chloride Option (brine).
