Abstract
In the present study, alum (aluminum sulfate) was dosed at a constant rate to a 2,000 gal/day activated sludge pilot plant. In addition to conventional secondary settling, filtration was used to remove residual organic solids and particulate phosphorus. The effect of pH on phosphorus removal was established.
