ABSTRACT:
An apparatus and method for separating an effluent into a filtered liquid component and a concentrated sludge component are described. A screen for filtering the effluent is positioned to divide a chamber into two compartments, one for concentrating sludge and one for receiving filtered liquid. The screen is curved in an arc that extends away from the liquid outlet, and a spray arm is mounted for arcuate motion to conform to the curvature of the screen to dispense a fluid against the screen to dislodge attached sludge, to unclog the screen apertures.
