ABSTRACT:
Systems and methods are provided for the removal of a contaminate from an aqueous medium using a zeolite-based sorption column. The systems and methods include an optimized relationship between the hydraulic loading, zeolite mesh size, distribution of zeolite mesh sizes and zeolite bed volume expansion to provide a highly effective sorption column that resists clogging while increases capacity.
