The Lewiston-Auburn Water Pollution Control Authority's (LAWPCA) wastewater treatment plant has, in recent years, experienced numerous permit violations related to excessive effluent suspended solids concentrations. These problems were attributed to a proliferation of filamentous organisms within the existing system and peak wet weather flow events.

Through a logical step-wise approach including preliminary demonstrations, computer modeling and process verification, LAWPCA proceeded with the implementation of the Selector-Contact-Stabilization (SCS) process. The SCS process addresses the two key facility issues; filament control and wet weather capacity. The SCS process has achieved excellent reduction of filamentous organisms through the use of an anaerobic selector without the benefit of excess phosphorus. The Selector-Contact-Stabilization process has, at times, been able to provide excellent removal of suspended solids during peak wet weather flow events.
