ABSTRACT:
A sewage sludge filtering system adapted for use with a polymer mixer for mixing a liquid polymer with sludge to produce an output mixture comprising coagulated sludge particles and water which comprises an elongated mesh hammock, a support arrangement for supporting the hammock in a generally horizontal orientation, and a piping system for communicating the output mixture to the interior of the hammock whereby the coagulated sludge particles are retained in the hammock and gradually dried as water escapes through the mesh of the hammock. An elongated filtrate tray is disposed under the mesh hammock for collecting filtrate and returning it to a sewage treatment facility.
