Belt Filter Press Dewatering of Wastewater Sludge

In recent years, belt filter presses have become one of the most popular methods for dewatering municipal sludges. Since their performance varies with the type of sludge being dewatered, pilot testing or extrapolation of data from other facilities has been usually used to design installations. In 1984, an ASCE Task Committee on Belt Filter Presses surveyed over 100 installations to compile data on performance and operating and maintenance requirements. These data have been analyzed and correlations obtained relating belt press loading rates and performance to feed solids. In addition, operation and maintenance requirements have been summarized from the 1984 survey.
