The environmental engineer knowledge in 2015: the selection of resin
2015.04.20 13:45Should be considered when selecting resin exchange capacity, water quality and the operation mode of ion exchanger, selecting proper resin.
Consider, for example, water quality, for eliminating water adsorption in the strong cation exchange capacity, and weak acid resin, optional for removal The adsorption of cation exchange capacity is weak, can only choose strong acid type cation resin. Considering the operation mode of ion exchanger, moving bed and moving bed Should choose wear-resisting, high mechanical strength of resin. Wet true density should be chosen for mixed bed, large difference of Yin, Yang resin. In addition, the exchange of different resin Capacity difference, and the same kind of resin exchange capacity is affected by the processing waste water of suspended matter, oil, high metal ion, etc.
