ABSTRACT:
A waste water treatment system and process for treating waste water received in a batch tank. The waste water is discharged in a headwork screen for removing large solids in the water. The solids are into a sludge drying bin. The screened water is transferred into a top of an influent surge tank with an oil/water separator. The oil/water separator includes a plurality of coalescing plates for separating free oil from the waste water. Heavy solids in the surge tank are drained into the sludge drying bin. The waste water is now dropped into a containment pan. From the containment pan, the waste water is pumped into a water treatment tank. The water treatment tank includes two or more electrodes mounted in the top thereof. The electrodes are separated using insulating support spacers for providing proper electrode spacing and insulation between the electrodes. The electrodes are used for providing current to the waste water and separating the contaminates in the water by electrocoagulation. The treated water in the water treatment tank is discharged after a completion of a period of settling or dwell time into a clean water tank.
