This presentation provides an overview of membranes used for thickening in aerobic digestion process. The benefits include: superior thickening without use of polymers; require very minimal operator attention; permeate can be sent to disinfection or to the head of the plant; and result in savings on hauling, operating, and energy costs....

This paper describes the Digestivore process, a new development that functions as a sludge handling system and also provides ammonia treatment of side streams at wastewater treatment plants. The Digestivore process is a very versatile and robust technology that features an aerobic digestion process utilizing flat plate membranes for thickening was...

Ceramic membranes have been around for quite some time, but the technology has often been cost prohibitive for many applications and markets. In the case of sludge thickening, the higher cost per square foot of membrane for ceramic is often offset by the potential gains in achieving sustainable operation at higher percent solids. Ceramic membrane...
