What Is The Specific Working Performance Of Water Softening Resin

Jul 21, 2020

Water softening resin is used in softened water, desalinated water, pure water and high-purity water preparation, sewage treatment, MSG manufacturing, pharmaceutical purification, chemical catalysis, rare metal separation and other aspects.


   Extra soft water resin is related to the following factors in the softening system:


   1. The working performance of the water softening resin is usually evaluated by the residual hardness of the treated water. For the tap water softening system, due to water quality requirements, a split treatment method of mixing thoroughly softened water with raw water can be used. For industrial applications, because the hardness of the treated water should be less than 5ppm, this can be 70-80kgNaCl/m3R regeneration level. If the softened water is supplied to an ordinary low-pressure boiler, the water quality requirement is that the hardness should be less than 1ppm, so at least the above two are required The regeneration level can meet the requirements. Under normal working conditions, the leakage of hardness is usually less than 1% of the hardness of the inlet water, and the working exchange capacity generally does not change much, unless the raw water contains sodium ions above 25%.


  In the civil softening system, a relatively low regeneration level is used, and the residual hardness is usually not required, and the influence of the medium and high flow rate operation on the working exchange capacity is also negligible. However, it is worth noting that to maximize the effect of the regenerant can be achieved by increasing the salt concentration and prolonging the regeneration time. The flow rate of the excess regenerant is also slow when regenerating, but the final removal of the excess salt requires the operating speed Come and clean it.
