Abstract A demonstration project at the Fort Wayne, Indiana Wastewater Treatment Plant is presented showing that the addition of a portion of the spent lime sludge from the city's water conditioning plant to the influent to the aeration tanks would slightly increase the normal capacity of the activated sludge to remove phosphorus. Duplicate pilot plants were evaluated for the removal of phosphorus by luxury uptake and acid elutriation and as a conventional activated sludge unit. Removals in both units were comparable to those attained in the full scale plant. Higher phosphorus removals were achieved when chemicals (lime, ferric chloride, polyelectrolytes, pickling acid) were used singly or in combination in the pilot plants. A survey of the flow and characteristics of the sewage in various locations in the City demonstrated that the concentration of total and soluble phosphorus varies with location and, therefore, can to some extent be controlled. Preliminary studies with a tertiary treatment pond receiving treatment plant effluent and storm water overflow indicate that BOD and suspended solids concentrations are substantially reduced during passage through the pond.
