Abstract
A coated granular filtration medium is formed by the deposition of an electrolyte layer onto core particles. The electrolyte layer comprises a cationic polyelectrolyte. The coated granular filtration medium provides a synergistic combination of filtration and in situ coagulation that enables efficient, effective, and economical decontamination of industrial and other wastewaters.
