The City of Gainesville (Georgia) has received from the Georgia Environmental Protection Division a Wasteload Allocation (WLA) for its Flat Creek Water Pollution Control Plant. The WLA includes a proposed effluent limit for total phosphorus of 0.13 mg/L. This concentration is lower than can be achieved using biological processes alone; therefore, chemical phosphorus removal will be required at the plant.

The City's consultant conducted bench-scale testing to compare five alternative chemicals for phosphorus removal. The consultant also reviewed the literature for treatment processes capable of achieving the proposed total phosphorus limit. From the processes identified, the City selected five for conceptual evaluation. Results of the bench-scale testing were used to estimate operating costs. Based on the results of the evaluation, the City selected the DensaDeg® process for full-scale implementation. The consultant conducted pilot testing of the DensaDeg® process followed by two types of media filters to confirm expected performance and to verify design criteria.
