This paper describes a cost effective induced air flotation process utilising the Jameson Cell technology to simultaneously remove algae and phosphorus from wastewater maturation ponds. This new treatment process has been shown to be capable of achieving algal removal efficiencies of over 98% and residual levels of total phosphorus to below 0.3 mg/l in the treated effluent. Optimum conditions for algal flocculation were identified using jar tests. Pilot plant trials were then carried out to examine the robustness of the chemical regimes found and to optimise the Jameson Cell operating parameters. Discussions are presented here on these results, as well as performance data from a recently commissioned full-scale installation. (C) 2004 Elsevier B.V. All rights reserved.
