METHOD FOR THE REMOVAL OF SUBMICRON PARTICULATES FROM CHLORINATED WATER BY SEQUENTIALLY ADDING A CATIONIC POLYMER FOLLOWED BY ADDING AN ANIONIC POLYMER

摘要

A method for removing submicron colloidal particulates, such as hydrocarbons, from water. The method includes first adding a soluble, cationic polymer, such as chitosan, a salt, or solution of chitosan to water containing the submicron particulates and a halogenating agent, followed by adding a soluble, anionic polymer or anionic salt to the water. The resulting flocs are filtered to remove the submicron particulates.
