A bipolar electrolyzer is provided which includes a plurality of bipolar electrode sub-assemblies which position the electrodes in the cells in a manner such that improved electrical operating characteristics are achieved. Each bipolar electrode sub-assembly includes an alternating stack of electrically insulating spacer members and bipolar electrodes. Electrodes are horizontally received in a channel in the electrically insulating spacer members which fixes the spaced relationship between juxtapositioned anodes and cathodes.

Bipolar electrolyzer having fixedly spaced apart electrodes

This invention is directed to a membrane or diaphragm-free electrolytic cell device for removal of a metal(s) present as a contaminant(s) in waste water comprising a nonconductive cell box having an upper peripheral flange, anode and cathode bus bars located on said cell box below said flange, inlet and outlet means to pass the liquid through the electrodes contained in said box, means to space the anodes and cathodes contained within said cell box, a plurality of anodes having openings to permit the flow of waste water therethrough, a plurality of reticulate cathodes, and means connecting the anodes and cathodes, respectively, to said bus bars and to a source of electrical energy whereby the metal contaminant(s) present in such water are deposited on the reticulate cathodes predominantly.

Device for waste water treatment

Disclosed are electrode assemblies which can be used to build a monoplanar membrane electrolytic cell suitable for the production of chlorine, alkali metal hydroxides and hydrogen having at least one central electrode assembly sandwiched between two end electrode assemblies with membranes therebetween to form a closed cell. Several of these resulting electrolytic cells can be connected in series or parallel to form electrolyzers very suitable for the electrolysis of a solution of sodium chloride or potassium chloride.
