A hypochlorite generator is disclosed which can make use of multiple, flat, plate-like bipolar electrodes. The electrodes are housed in non-conductive casing members which can be outfitted with fastening means that facilitate easy access for inspection and cleaning of electrodes. Bipolar electrodes are recessed in the casing members whereby a fluid flow passageway is left between plate electrodes. Desirable fluid flow velocities may be achieved, coupled with excellent cell efficiencies.

Bipolar rapid pass electrolytic hypochlorite generator

A compact, relatively small unit for treatment of wastewater for discharge into maritime waters is disclosed. The wastewater is received in a surge or retention tank and is delivered by gravity flow or pumped to a macerator for comminution of the solids content of the wastewater. Prior to entering the macerator, salt water on a controlled flow basis is added to the wastewater in sufficient amounts to insure a high enough salt content for use as the electrolyte in an electrocatalytic cell. From the macerator the wastewater to be treated is directed into a vertically oriented, elongated, electrocatalytic cell having a plurality of parallel, closely spaced electrodes therein positioned parallel to the flow of wastewater therethrough. The wastewater is directed through the electrocatalytic unit. The end electrodes of the spaced electrode plates are connected to a source of direct current sufficient to generate chlorine, oxygen and other treating chemicals in situ. The gases generated in the cell, entrained with the liquid, flow out of the electrocatalytic cell with the liquid into the standpipe of an effluent tank where a negative pressure separates the entrained gases from the liquid and vents them to the atmosphere. The heavier solids remaining in the discharged treated liquid are allowed to settle in the bottom of the effluent tank and the remaining effluent is discharged.
