  • Patent number: 6613202
    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.

A side of the first compartment includes an opening for receiving an electrode assembly with a plurality of electrodes extending inside the compartment. 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. A filtrate sump is mounted in the bottom of the tank housing.

  • Patent number: 6179977
    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.

  • Patent number: 6135293
    Abstract: A water/sludge filter press used with a filter bag for filtering water and collecting sludge in the bag. When the filter press is actuated, the filter bag is compressed therein for dewatering the sludge in the bag for ease in removing the sludge and reusing the bag or replacing the bag. The filter press includes a horizontal stand with an upright vertical press frame. A hydraulic cylinder with piston is mounted on the vertical press frame. Attached to the vertical press frame is an open-top housing adapted for receiving the filter bag therein. The sides and bottom of the housing are lined with screens for passing filtered water therethrough. The housing includes a first vertical side, a second vertical side, a stationary vertical press plate, a vertical movable press plate and a foldable bottom. The foldable bottom includes a pair of pivot arms attached to the piston of the hydraulic cylinder. The foldable bottom is also attached to a lower end of a pair of coil springs.

  • Patent number: 6063272
    Abstract: An activated carbon filter is regenerated while it remains positioned in a filter vessel by first draining both unfiltered and filtered water out of the vessel and then applying an electric current through the activated carbon body of the filter to drive off contaminants. An inert gas is directed through the filter in a direction opposite to that of the liquid flow and then contaminants are moved from the filter vessel to a multi-stage catalytic converter where they are completely oxidized.

  • Patent number: 5423962
    Abstract: Polarizing conductive conduits are mechanically and electrically mounted to respective ones af a pair of electrodes to which a voltage source is connected to establish an electric field between the electrodes. Liquid to be purified is first passed through one or more of said conduits and then passed between said electrodes to precipate or coagulate materials contained in said liquid.
