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: 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.
