Abstract:
A water treatment tank for treating waste water using an electrochemical treatment process, the electrochemical process removing both suspended and dissolved solids and contaminates in the waste water and allowing treated water to be removed from the tank while heavy contaminates settle to the bottom of the tank as sludge and are removed and lighter than water contaminates are removed by vacuum from the top of the tank, the tank comprising:a tank housing, said tank housing including a waste water receiving compartment, said compartment having sides, a top and a bottom, said compartment adapted for receiving waste water to be treated therein, one of the compartment sides having an annular opening therein for receiving a non-conductive annular hollow flange tank mounting plate attached to the side of the annular opening; a vacuum pump with a vacuum inlet line connected to said compartment, said vacuum pump adapted for drawing a vacuum inside said compartment and removing lighter than water contaminates; means for removing treated water from said compartment and attached thereto; an electrode assembly having a non-conductive annular flange electrode mounting plate attached to one end of a plurality of spaced apart positive and negative electrodes, said electrodes extending through said hollow flange tank mounting plate and inside said compartment for treating the waste water electrochemically when electrical power is applied to said electrodes, said electrode mounting plate removably attached to said tank mounting plate; and means for collecting sludge received in the bottom of said compartment, said means for collecting sludge disposed below the bottom of said compartment.
