Abstract

Implementations herein relate to methods for reducing a desorption solution for regeneration of ion exchange resins in the field of regeneration of resins. The implementations solve problems related to low utilization rates of regeneration agents and high volumes of desorption solutions during the desorption process. The implementations include regenerating the ion exchange resins, and the regeneration solution becomes the desorption solution. After coagulating sedimentation of the desorption solution and slurry separation, a large amount of organic contents are removed from coagulation serum and a large amount of regenerate agents are left. The implementations further include adding the regeneration agent to the coagulation serum to form new or refreshed regeneration solution to regenerate the ion exchange resins. Accordingly, the coagulation serum may be generated from the desorption solution. These operations may be repeated multiple batches for resin regeneration.
