This research was conducted using jar tests to investigate the impact of adding activated sludge solids to the Actiflo® process, a high-rate clarification (HRC) system, to increase BOD removal in HRC systems treating raw wastewater during periods of high wet-weather flows (WWF). A study of dosages and impacts of ferric sulfate, polymer, microsand and activated sludge on performance of the Actiflo® process was investigated. Experiments were designed to determine the dosages of activated sludge and other chemicals necessary to achieve an effluent BOD5 level of 30mg/L in this physical-chemical process with an influent BOD5 concentration of 100 mg/L. With a 490 mg/L dose of activated sludge and 15 minutes mixing time, the effluent BOD removal efficiency was enhanced by approximately 30% using lower chemical dosages in jar tests.
