SYSTEMS AND METHODS FOR RECYCLING WASTE ION EXCHANGE MATERIALS

Abstract:

Embodiments of the present disclosure are directed to methods for recycling waste ion exchange materials comprising a first alkali metal salt and a second alkali metal salt comprising reducing the size of the waste ion exchange materials to produce a plurality of waste ion exchange particles having particle sizes from 0.10 mm to 5.0 mm, and regenerating the plurality of waste ion exchange particles to produce a plurality of regenerated ion exchange particles having a concentration of the first alkali metal salt greater than a concentration of the first alkali metal salt in the waste ion exchange materials. Systems for recycling a waste ion exchange materials comprising a first alkali metal salt and a second alkali metal salt are also disclosed.
