  • Publication number: 20060138053
    Abstract: According to the present invention, there is provided a wastewater processing apparatus and method comprising a rotating filter thickener (20) receiving and filtering a wastewater mixture and producing a first filtrate output and a first sludge output, a screw press thickener (24) receiving the first sludge output and forming a final sludge output and a second filtrate output, a dissolved air floatator (46) receiving the first filtrate output from the rotating filter thickener (20) and producing a first solid output and a third filtrate output, a first conductor (10, 12, 29) for mixing incoming raw manure wastewater and the second filtrate output from the screw press thickener (24) to produce the wastewater mixture for input to the rotating filter thickener (20), and a second conductor (34) for branching off a part of the first filtrate output to a spray cleaner (38) for spraying the part of the first filtrate output onto the filtration disks (70) for their cleaning.
