Abstract: In this paper, the relevant factors affecting the effluent effect of activated carbon tank are theoretically analyzed to provide the basis for the selection and maintenance of activated carbon tanks. The activated carbon tank can prevent patients from hemolytic anemia by effective removal of residual chlorine, and also help prolong the usage of reverse osmosis membrane and resin by preventing chlorine oxidation. In order to protect the resin and reverse osmosis membrane and to ensure the safety of dialysis water quality, parameters of activated carbon should be carefully considered in the preparation of activated carbon tanks.

Key words: activated carbon, dialysis water treatment, removal of chlorine, Calculation of water consumption for dialysis
