The self dumping sludge dewatering box is an economical, one step method to separate water and sludges or solids.

Typical Sludge Dewatering Box Uses

  • Pretreatment of wastewater to remove solids prior to discharge in the City Sewer
  • De-water sludge or solids prior to disposal os solids in a landfill.
  • Remove suspended solids to lower TSS (Total Suspended Solids)
  • Recover water or solids from wastewater.

How The Sludge Dewatering Box Works

Wastewater or sludge is pumped in to the self dumping dewatering box where separated waster will drain by gravity through the bottom filter screen. The separated water after draining through the filter media will discharge from the dewatering box through a 2 inch female outlet on the box located near the bottom on the back side of the dewatering box. An optional Air Operated Diaphragm (AOD) pump can be used to pull a vacuum on the box to aid in dewatering.

Not sure what to use? Contact us and we will send a free sample kit with a 20” by 20” sample of the filter papers for you to test. Note: Heavier papers are available but require a vacuum pump to efficiently filter water. Filters can be easily cleaned in place or removed for cleaning. To remove the filter simply unbolt the filter frame and remove the filter.
