Abstract

The treater employs a pair of closely spaced, superimposed circular electrode plates, and the liquid to be treated is passed through the limited area between such plates in a pressurized sheet such that the liquid tends to clean the electrodes at the same time as it receives treatment thereby. An annular groove adjacent the discharge periphery of the lower plate has the effect of causing the discharging sheet to assume an umbrella-like configuration to promote aeration of the discharging liquid. If desired, the plates may be associated with a receptacle in such a way that the umbrella-like discharging sheet engages the walls of the receptacle at one electrical polarity while at least one of the electrode plates is of the opposite electrical polarity so as to promote effective treatment. On the other hand, if desired, the plates may be submerged within such a receptacle adjacent the sludge collecting at the bottom thereof. In one embodiment the opposed plates are of the same electrical polarity while another electrode situated upstream from the plates is oppositely charged.
