Abstract: A water treatment tank for treating waste water using an electrochemical treatment process. The electrochemical process removes both suspended and dissolved solids in the water and allows the treated water to be removed from the tank for reuse or discharge. The tank includes a tank housing with first and second waste water receiving compartments. The two compartments are identical and are used alternately when treating the waste water. A waste water inlet line is attached to the top of the first compartment for filling the compartment with waste water. A side of the first compartment includes an annular opening for receiving an electrode assembly with a plurality of electrodes extending inside the compartment for treating the waste water electrochemically. The electrodes are attached to the power supply via electrode cables with the polarity of a current cycle reversed periodically depending on the types of water contaminates being treated.

Abstract: Insitu process equipment for the electrochemical treatment of contaminated water in a pit or lagoon such as an oil drilling reserve pit. The insitu process equipment uses a minimum of equipment for removing both suspended and dissolved solids in the water and allowing the treated water to be decanted from the pit or lagoon for reuse or discharge. The process equipment includes a floatation device in the form of a plurality of lightweight foam filled barrels rotatably mounted on drum axles. The drum axles are attached to an elongated barrel frame. A pair of electrode assemblies with a plurality of electrodes are attached to opposite sides of the barrel frame. The electrode assemblies are pivotly mounted on the barrel frame for lowering the electrodes below the water level when the process is in operation. An electrode cable guide is mounted on top of the barrel frame and the barrels for holding electrode cables. One end of the electrode cables are attached to opposite ends of the electrode assemblies.
