Abstract: A plate settler arrangement for a liquid clarification system is disclosed. The plate settler is disposed in a clarification tank or basin in a liquid clarification system. Liquid flows into the space between adjacent plates and out of the basin through outlet members disposed in the upper region of the spaces between the plates.

Abstract: A sludge removal system for removing sludge from a clarifier tank is disclosed. The system comprises a movable sludge intake manifold, a stationary sludge outlet conduit and one or more conduits dynamically and fluidically connecting the manifold and the sludge outlet conduit, even as the manifold moves relative to the stationary sludge outlet. One or more of the conduits between the manifold and the outlet are connected in the system through rotatable conduit connectors which is part of the dynamic connection mentioned above. Improved sludge intake constructions are also disclosed.

Abstract: A clarifier support structure for supporting tube or plate modules in a clarifier tank or basin is disclosed together with a method for installing the structure in a tank or basin. The structure comprises a first laterally extending truss supported on first and second opposed walls of the tank, a longitudinally extending truss supported at one end on the laterally extending truss and at a second end on a transversely extending wall of the tank, a first module support member supported at its ends on the first opposed side wall and on said longitudinally extending truss, and a second module support member supported at its ends on the second opposed side wall and on said longitudinally extending truss.
