Abstract:

Rockaway Valley Regional Sewer Authority in New Jersey and the City of Springfield, Missouri both currently utilize traditional gravity thickeners to thicken their municipal wastewater sludge. Both cities would like to improve their sludge thickening process control and performance. In response to their needs, Alfa Laval pilot tested the ALDRUM MidiĀ® Rotary Drum Thickener (RDT) at each facility in 2008.

The goals of these projects were to demonstrate the RDT's technological advancements, superior performance and quick responses to process changes in raw sludge applications (as tested in Rockaway Valley) and waste activated sludge applications (as tested in Springfield). Performance curves for thickened solids, polymer consumption, and recovery throughout the RDT's operating range were developed.

At both facilities, the RDT satisfied performance expectations, meeting the established goals for thickened sludge, polymer dose, recovery, and throughput. By meeting these goals, the RDT also proved to effectively help to reduce operational costs.
