520 3 |a This study investigated the characterization and flocculation mechanism of a bioflocculant prepared using potato starch wastewater. The optimal culture conditions of this strain were determined as 4g K2HPO4, 2g KH2PO4, 0.2g MgSO4, 0.1g NaCl, and 2.0g urea dissolved in 1.0L potato starch wastewater with no need of adding carbon sources or adjusting pH value. Production of this bioflocculant was positively associated with cell growth, and a highest value of 0.81g/L was obtained. During the kaolin suspension flocculation, charge neutralization and interparticle bridging were proposed as the main reasons for enhanced performance. Further, with potato starch wastewater, chemical oxygen demand (COD) and turbidity removal rates reached 52.4 and 81.7%, respectively, at pH7.5 when the bioflocculant dose was adjusted to 30mg/L.
