    Abstract: The invention relates to a system for the thickening of sludges, in particular domestic sewage or industrial waste sludges. The system comprises two or more consecutively arranged thickening stages each consisting of one thickening tank or several parallel thickening tanks, and wherein the ratio of the largest inside diameter to the mean sludge level is larger than 1:1 in the first tank and smaller than 1:1 in the second tank relative to the direction of sludge flow.

    Abstract: The invention relates to clarifying apparatus, such as settling tanks, provided with a bridge member which rotates in a horizontal plane above the suspension of solids being treated in the tank. The tank is free of any central supporting column for the bridge member and the bridge is supported at least at one end by the outer wall of the tank. A bridge support member, rigid with the tank, extends over the tank above the rotatable bridge member and provides a central pivot for rotation of the bridge member. The bridge support member may extend diametrically across the tank and may support the bridge member.

    Abstract: A surface aerator in a tank creates horizontally directed surface flow that forms waves as the flow progresses through the tank and impinges upon the tank wall. At least one substantially horizontal baffle is mounted adjacent the inner wall of the tank adjacent or subjacent the liquid level and is positioned at a point of high wave amplitude to attenuate the waves by eliminating the vertical energy component thereof. The baffle may have a passage therethrough for circulation of liquid.

    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 Clarified water is removed from the top of the clarifier and sludge is withdrawn from the aerating chamber.
