Abstract:
A system for filtering waste water, comprising:a tank for holding waste water, having forward and rearward walls, opposing end walls and a bottom;said tank including in inlet port for receiving waste water, and an outlet port for dispensing filtered water;a first anode element suspended within the tank, for providing a positive charge to particulate within waste water in the tank;a first cathode element suspended within the tank and spaced from the first anode, for attracting and holding positively charged particulate, to thereby remove the particulate from the water;a DC power supply having a positive terminal electrically connected to the first anode and a negative terminal electrically connected to the first cathode;said first anode including a sheet of electrical conductive material having a mesh of apertures of a size sufficient to permit the flow of waste water with particulate therethrough;said anode sheet being oriented generally vertically within the tank and extending substantially between the tank forward and rearward walls and from the tank bottom to proximal upper edges of the tank walls;said first cathode including a sheet of electrically conductive material having a mesh of apertures of a size sufficient to permit the flow of waste water with particulate therethrough;said first cathode including a second electrically conductive mesh sheet spaced from and parallel to the cathode first mesh sheet, and further including a frame forming a box with the two mesh sheets forming two sides of the box.said first cathode sheets being oriented parallel to the first anode sheet, and extending substantially from the tank forward wall to the rearward wall and from the tank bottom to proximal the tank wall upper edges;and electrically conductive shavings filling the first cathode box from between the cathode sheets.
