ABSTRACT:
As industrial waste water is passed through an electric field between a pair of uninsulated electrodes, suspended solids and other constituents are acted upon in a manner that encourages them to flocculate. In order to assure that the water is exposed to the field for a sufficient period of time, a normally closed shut-off valve in the outlet of the treater stays closed until electrolysis commences, whereupon gas pressure from such action actuates a diaphragm member which in turn closes a switch to open the outlet valve. A float control associated with the inlet of the treater responds to the drop in water level within the treater by opening an inlet valve to permit the introduction of additional liquid.
