Inline Sludge Screens for Municipal and Industrial Applications

Even where fine screens are installed in the headworks of wastewater treatment plants, some debris will always end up in the sludge. Plastic parts and fibrous materials can severely disturb the operation of thickeners, digesters and dryers. Such solids impair the operation of pumps, heat exchangers, mixers, dewatering systems, pelletizers, etc. Hair and fibers often lead to the formation of tresses and grease balls. Where biosolids are land applied, plastic parts should be removed.

Such undesired solids should be removed from the sludge before causing problems in downstream processes and machines. Grinders might reduce the issues but they do not remove disturbing solids and are high in maintenance. Only screens can effectively remove debris from sludge in industrial processes. Excellent dewatering and compaction of the removed material is a huge advantage because it ensures a clean and safe environment and volume reduction. Sludge screens should be entirely enclosed for odor control.

Removal of screening, hair, and fibers from sludge
  • Reduced maintenance
  • Improved process efficiencies
Inline pumping capability
  • Retrofits current piping
  • Does not require breaking to atmosphere
Screening & dewatering in a single step
  • Reduced hauling costs
  • No process water required
