ABSTRACT:
An electric treater for promoting flocculation of suspended solids in a liquid is provided with special scrubbing brushes that bear against electrodes of the treater tending to accumulate a layer of adhering ionic particles so as to dislodge and remove the particles from the electrodes in order to promote optimum electrodic action. In one form of the invention the electrodes are disposed concentrically one within the other, and as the inner electrode rotates, a hinge-action brush associated with the stationary electrode bears against and cleans the rotary electrode while a similar hinge-action brush associated with the rotary electrode bears against and cleans the stationary electrode. Interengaging cam components flip the brush on the rotary electrode momentarily out of the path of travel of the stationary brush during each rotation to avoid interengagement of the brushes. In another form of the invention, hinge-action brushes on rotary supports sweep into engagement with oppositely rotating electrodes and snap through a quick-flip self-cleaning action under the influence of a strong return spring after sweeping out of engagement with the electrode. The rotary supports may be intermittently started and stopped to index the brushes at 90.degree. intervals, whereby to hold the brushes in scrubbing positions or in mutually opposed relationships with one another such that by electrifying the metal bristles of the scrubbers, an electric, treating field may be established therebetween for auxiliary treating action.
