This paper describes a research to use an innovative combined biological process, upflow sludge blanket filter (USBF), that rapidly and economically remove BOD, nitrogen and phosphorus from piggery wastewater. The USBF design is a continuous flow system incorporating the aeration zone, clarifier and anoxic zone into a single tank. The research showed a result of 97%, 80%, 94%, 90% and 85% for COD, BOD5, SS, nitrogen and phosphorus removal, respectively. This is concluded that USBF can be used as a simple and economic method to treat pigerry wastewater.
