Abstract: A solid-liquid separator for sludge which includes a tank with a sludge suction port, an intake/exhaust port and a sludge discharge port. A plurality of agitating blades are mounted on a rotatable shaft within the tank and are capable of being driven in either of two rotational directions. A plurality of injection nozzles are internally mounted on the bottom of the tank in such a manner as to eject a mixture of sludge coagulant and air into sludge contained within the tank. A pump which is capable of producing a vacuum or pressure is connected to the intake/exhaust port so as to produce either a vacuum or a pressure within the tank and the sludge suction port is adapted to be connected to a source of sludge to intake the sludge into the tank. The injection nozzles are connected to a source of sludge coagulant and air. The disclosure also relates to the method of treating the sludge to separate into solid and liquid phases.
