Belt Press Rehabilitation

Belt press-to process biosolids and remove excess water

The District completed repairs of the existing belt filter press. A Belt Filter Press is a biosolids/sludge dewatering device that applies mechanical pressure to a chemically conditioned slurry, by squeezing the sludge through a serpentine of decreasing diameter rolls.  Typically, a belt filter press receives a slurry ranging from 1-4% feed solids and produces a final product of 12-35% cake solids. Performance of the belt press depends on the nature of the solids being processed.

In addition to the belt filter press repairs, two progressive cavity sludge feed pumps that were installed in 1985 were rehabilitated as part of this project.
