Abstract: A system for active sludge waste water treatment comprises an aerating chamber and a clarifying chamber. Raw water is introduced into the aerating chamber where liquid is circulated in a path in the aerating chamber and the liquid is aerated. A portion of the circulating liquid is conveyed to the clarifying chamber where the sludge settles to the bottom. Settled sludge is conveyed from the bottom of the clarifying chamber and introduced into the aerating chamber in a direction substantially the same as the direction of motion of the liquid in the path of circulation in the clarifying chamber. Clarified water is removed from the top of the clarifier and sludge is withdrawn from the aerating chamber.
