摘要： A device for diverting the flow of liquid in a wastewater treatment system in flow communication with effluent returning from a recirculating treatment section and in flow communication with a discharge line for removing a portion of treated effluent to a receiving body. The device also has openings for returning a percentage of the effluent back to the wastewater treatment system. A valve operatively responsive to a float in the treatment system whereby when the effluent level in the system falls below a critical point, all of the effluent is recirculated back into the treatment system and when the effluent level rises sufficiently a percentage of cleaned effluent exits the system.

摘要： A filtering device includes a container having an inlet for introducing liquid to be treated, an annular multi-layered prepacked screen assembly provided in the container and having an outlet for treated liquid. The screen assembly includes three or more cylindrical screens having different diameters and being coexially disposed in the container with their axes extending vertically in the container. An annulus is formed between the respective cylindrical screens. Two or more different filter materials performing different filtering functions are filled one in each of the annuluses between the cylindrical screens.
