Fact Sheet: Belt Filter Press

Belt filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as “cake.” Dewatering wastewater solids reduces the volume of residuals, improves operation, and reduces costs for subsequent storage, processing, transfer, end use, or disposal among other benefits.

The biosolids technology fact sheet for belt filter presses provides:

  • A description of the belt filter press
  • Applicability to wastewater treatment plants
  • Advantages and disadvantages the belt filter press
  • Design criteria
  • Performance capabilities and data
  • Operation and maintenance information
  • Costs
