Human activities around the world are responsible for production of enormous amount of wastewater, which needs to be treated quickly and effectively to avoid environmental concerns and other health implications. As an alternative to primary settlers in treating municipal wastewater, Salsnes, a subsidiary company of Trojan Technologies offers rotating belt filters (RBF) to treat the wastewater. A bench scale filtration unit of the RBF was developed to investigate the effect of varying water qualities from several wastewater plants in London, Ontario on the performance of the filter. The unit can achieve up to 80% reduction in total suspended solids (TSS), and 60% reduction in COD. As expected, flux of the filter meshes decreases with continuous filtration, while TSS, COD removal efficiency increases due to cake filtration. Performance models were developed correlating flux and removal efficiency with important influent water quality parameters such as TSS and COD using regression analysis
