Belt PressThe belt press is most useful when a continuous operation is desirable. Typically, a belt press produces between 18% and 25% solids by weight in the cake.

Belt presses work by removing sludge onto two different dewatering belts where freestanding water molecules are separated from the sludge by gravity and are collected by a trough. Next, the thickened sludge is pressed between two belt filters and squeezed under rollers to force excess water from the sludge. Finally, the sludge is scraped off the belt and collected in a bin while the water content is transferred back into a wastewater system for processing.

Since the belt press performs a continual action, it is most effective on high-volume waste streams. It is commonly used for the following applications:
  • Paper mill sludge
  • River silt
  • Municipal wastewater treatment plants

When deciding if a belt press is right for your sludge dewatering project, it is important to consider the overall objective, disposal options, and cost of dewatering when deciding which the best choice for your specific needs is.

At Handex, our objective is to meet and exceed client expectations while providing quality, safe and cost-effective services. In some cases, our clients find that the value of the materials returned to the plant pays partially for the cost of the sludge dewatering service.
