Abstract: The formation and performance of granular sludge was studied in an 8l sequencing batch reactor (SBR) treating an abattoir (slaughterhouse) wastewater. Influent concentrations averaged 1,520 mg l(-1) volatile suspended solids (VSS), 7,685 mg l(-1) Chemical oxygen demand (COD), 1,057 mg l(-1) total kjeldahl nitrogen (TKN), 217 mg l(-1) total P. The COD loading was 2.6 kgm(-3)d(-1). The SBR was seeded with flocculating sludge from a SBR with an 1h settle time, but granules developed within 4 days by reducing the …
