ABSTRACT:
An improved electro-coalescent/magnetic separation (ECMS) system for removing contaminants from water, including desalinization, comprises a device for exposing a stream of water to be treated to an electric field, followed by introduction of ionized coagulating substances, including ionized gases and/or metal ions, followed by plural filter stages. The first filter stage may comprise a polarizable glass, alumina, or ceramic media provided as a bed in a tank with an underdrain, so as to provide substantial residence time. A polishing filter may comprise a very fine fiber or organic gel filter element confined between relatively flexible electrically-conductive screen members and provided with a DC power supply to polarize the filter. This assembly is confined between relatively rigid, perforated members such that the filter assembly can move slightly upon backwash to dislodge caked-on contaminants or the like, while preserving the structural integrity of the filter assembly.
