Claim:
1. A method for reducing a desorption solution for regeneration of ion exchange resins, the method comprising: (a) mixing a regeneration solution and the ion exchange resins for about 10-120 minutes to regenerate the ion exchange resins, the regeneration solution becoming the desorption solution; (b) adding a coagulant to the desorption solution to perform coagulating sedimentation; (c) performing a slurry separation on the desorption solution after the coagulating sedimentation to form a coagulation serum and to generate an amount of sludge that is disposed; (d) adding an amount of a regeneration agent to the coagulation serum to form modified regeneration solution; (e) performing operations of the step (a) using the modified regeneration solution formed in the step (d) to regenerate the ion exchange resins; (f) repeating a plurality of batches of the steps (a) to (e); and in response to a determination that the regeneration solution fails to satisfy a predetermined condition, disposing the desorption solution.
