Multi-layer recirculating filter wastewater treatment apparatus



Multi-layer recirculating filter wastewater treatment apparatus



Official Gazette of the United States Patent & Trademark Office Patents 1274(2), Sep 9



A wastewater treatment unit (10) including a recirculation chamber (32), a dosing chamber (34) having no direct fluid connection to the recirculation chamber (32), and at least two filter layers (28, 30) in a single tank (12). Each filter layer (28, 30) containing filter media (56) and being located above the recirculation (32) and dosing chambers (34). The wastewater treatment unit (10) also including an influent pipe (50), a recirculation pump (72) located in the recirculation chamber (32), and an effluent discharge pipe (88) connected to the dosing chamber (34). The influent pipe (50) directs wastewater entering the wastewater treatment unit (10) into the recirculation chamber (32), the recirculation pump (72) pumps the wastewater from the recirculation chamber (32) onto the filter layers (28, 30); the wastewater flows through the filter media (56) of the filter layers (28, 30) and is directed to the recirculation (32) or the dosing chamber (34); and the wastewater is discharged from the wastewater treatment unit (10) through the effluent discharge pipe (88).
