Abstract

227,988. Paterson, W. Dec. 31, 1923. Gravity-separation apparatus. - A settling-tank for sewage or waste water is provided with one or more channels at the bottom along which the incoming liquid is directed from a controllable opening so as to flush solid matter left after a previous settling through an apertured wall d into a sludge chamber c separated from the tank by the wall d. The channels may be formed by dwarf walls f and the inflow of the liquid controlled by sluices i. A circular tank may have a single spiral channel in a conical floor leading through an apertured wall to a central sump.
