Abstract The sequencing batch reactor (SBR) was used for in situ studies of piggery wastewater treatment. The SBR was a concrete basin 5 mL × 2.5 mW × 4 mH. The study was performed on a selected pig farm in Taiwan. The working volume was 37.5 m3 and hydraulic retention time (HRT) was 3 days with the BOD volumetric loading of 0.357 kg‐BOD/m3/day. The removal rates of BOD, COD, and SS were 94.5, 88.7, and 93.4%, respectively. However, the removal rates of nitrogen (NH4 +‐N, NO3 −‐N, and TKN) and phosphorus were 36.3–52.9 and 61.1%, respectively. The results imply the feasibility of extending SBR system to pig fanners for piggery wastewater treatment in Taiwan.
