Softeners Water softeners can be Found possibly upstream or downstream of disinfectant removal units. They make use of sodium-primarily based cation-exchange resins to get rid of drinking water-hardness ions, for example calcium and magnesium, that could foul or interfere Using the functionality of downstream processing products which include reverse osmosis membranes, deionization equipment, and distillation models. H2o softeners will also be made use of to remove other reduce affinity cations, such as the ammonium ion, That could be launched from chloramine disinfectants frequently Utilized in consuming drinking water and which might in any other case carryover by way of other downstream unit operations.
