Abstract: Water purification apparatus and method. In a specific embodiment, domestic sewage (exemplary of water from municipal, domestic or industrial sources which may be processed with the invention) is purified by passing the sewage through a hydraulic macerator to reduce mechanically the size of solid waste products entering the system, and to aerate the waste. The macerated sewage may then be passed through an electrolytic cell having a plurality of spaced metal electrodes. Within the cell, electrolysis of the sewage produces oxidizing agents effective to kill harmful bacteria and other microorganisms. The electrolysis converts the sewage into a form which is essentially free of the usual pathogenic fecal organisms including Escherichia coli, Staphlococcus sp., Bacillus sp., other coliforms, Sacchromycetes, various molds and other fungi.

Abstract: AN IMPROVEMENT IN THE ELECTROLYTIC TREATMENT OF WASTEWATER IS DESCRIBED IN WHICH THE REDUCTION OF OXYGEN ON AN ACTIVATED CARBON CATHODE IS EMPLOYED TO FORM HYDROGEN PEROXIDE, WHICH IN TURN SERVES TO OXIDIZE ORGANIC CARBON POLLUTANTS IN THE WASTEWATER. THE OXYGEN IS FED TO THE ACTIVATED CARBON CATHODE FROM OUTSIDE THE ELECTROLYTIC

CEIL, WITH THE CATHODE MEMBER DEFINING AT LEAST PART OF THE ENCLOSURE FOR FEEDING THE GAS TO THE ACTIVATED CARBON CATHODE SURFACE, AND WITH THE CATHODE SURFACE FORMING PART OF THE BOUNDRY OF THE CELL COMPARTMENT.

Abstract: Water treatment apparatus comprising the serial arrangement of spaced apart parallel disposed plates positioned in the water being treated. Consecutive plates are oppositely polarized at a relatively low voltage. The polarization of the plates is periodically reversed to prevent residual buildups on the plates. The apparatus acts to kill bacteria, to aerate the water being treated and to increases the circulation of the water.

Abstract: An electrolytic cell for direct electrolysis of sea water wherein the cathode plates are parallelly elongated upward and downward longer than the anode plates to prevent Mg(OH)2 from adhering to said cathode plates and further prevent impurities from depositing in the cell to increase the efficiency of the electrolysis. The cell includes a feed chamber below the electrolysis chamber, and an electrolyte takeoff-precipitate withdrawal chamber directly above the electrolysis chamber, with the outlet port from the electrolysis chamber coincident with the inlet port to the electrolyte takeoff-precipitate removal chamber.
