Abstract: One embodiment of the invention provides an electrolytic treatment unit comprising a casing, a plate bundle, a cathode and an anode. The casing has a longitudinal axis. The plate bundle is positioned in the casing. The plate bundle comprises a plurality of spaced-apart parallel plates and each plate is positioned normal to the longitudinal axis. The cathode or anode are connected to selected plates of the bundle. Another embodiment of the invention provides an electrolytic treatment unit comprising a casing, a baffle separating the casing into first and second compartment, and a plate bundle positioned in each compartment. A cathode is connected to one bundle and an anode to the other bundle. A product stream is taken from each compartment. To achieve needed throughput at low head, the plates are spaced in the range of 1 cm to 10 cm apart.

Abstract: Method and apparatus are provided for treating salt water. In the method, a feed water is run through a skimmer unit to form de-oiled water. The de-oiled water is passed through an electrocoagulation unit to form electrocoagulated water. A precipitating agent is added to the electrocoagulated water and stirred to form a water/floc mixture. A polymeric coagulation enhancing agent is added to the water/floc mixture with mild stirring and coagulants in the mixture are permitted to settle. A partly clarified water from the mixture is drawn out from a level above the settled coagulants. The partly clarified water is run through at least one settler and coagulants are removed from the bottom of the at least one settler. A clarified salt water stream is withdrawn from the final settler. The necessary equipment can be mounted on a trailer. The trailer can be provided with a stairway and catwalk to facilitate safe inspection.
