Abstract A recirculating sewerage system including at least one water closet, a recirculating tank including effluent receiving and pumping chambers separated by a common wall, the common wall supporting a filter for restricting the passage of bulk waste including paper products which float on the top of the received effluent from the effluent receiving chamber to the pumping chamber, a pump including a filtering element for drawing liquid effluent from the pumping chamber and for directing the drawn and filtered liquid effluent to the water closet to flush same, the means for creating turbulence proximate the upper surface of the effluent within the effluent receiving chamber adjacent the filter when the pump is actuated whereby the flow of the floating paper products from the effluent receiving chamber to the pumping chamber during actuation of the pump will be inhibited.
A recirculating sewerage system comprising a recirculating tank including effluent receiving and filtrate compartments separated by a vertically extending common wall, at least one water closet adapted to discharge the effluent flushed therefrom into said receiving chamber, said common wall including filter means for inhibiting the passage of bulk waste from said effluent receiving chamber into said pumping chamber, a rinsing manifold extending adjacent to and along the top of said filter means and including a plurality of apertures opening downwardly proximate said filter means, flush pump means communicating with said filtrate compartment, means for conjointly directing a major portion of the pressurized filtrate discharged from said flush pump means to said water closet to flush same and a minor portion of the pressurized filtrate discharged from said flush pump means to said rinsing manifold.
