ABSTRACT:
Apparatus for feeding the raw influent water into a center post clarifier including an uptake zone defined around the center post forming an eductor tube having an upper and lower end respectively in communication with an upper and lower portion of the mixing and recirculation chamber. A first set of openings is provided intermediate the center post for directing the flow of raw water upwardly into an intermediate portion of the uptake zone. A second set of openings positioned above the first set of openings is provided for directing the remaining flow of raw water from the center post into an upper portion of the uptake zone. The relative flow rates of raw water through the first and second openings being such as to cause sludge which has accumulated adjacent the lower end of the uptake zone to be lifted therein to and recirculated with the raw water. Means are provided to selectively control the flow rates of raw water through the first and second openings to adjust the sludge recirculation rate.
