Sludge Dewatering Improvements

Chief Operator: Jim Vrooman

Engineer: O’Brien & Gere Engineers, Inc.

Project Summary:

In the early 1980s, the Village upgraded its sludge handling facilities. Several sludge

dewatering technologies were evaluated. A belt filter press was chosen as the most cost effective equipment for the Village. Once installed, the manpower and maintenance

requirements for the dewatering operation were reduced from five days per week to one

day per week. The press also produces a dryer cake (28% solids by weight) than the previous vacuum filter cake. The Village stabilizes the sludge with lime prior to ultimate disposal.

Our special thanks to Jim Vrooman, Chief Operator. Jim is responsible for the successful operation of the dewatering equipment. The belt press and related items have been operating reliably for over 15 years.
