Compact Screen & Grit Removal Package

Model ICE 

This primary treatment machine provides screening and grit removal in a single compact process package plant.

First, the untreated sewage passes through a screw screen that removes the larger floating and suspended materials (screenings). The screened sewage then travels through a sedimentation tank where sand and heavier particles (grit) settle, for removal by a system of screws.

As an option, this system can be configured to remove fats, oils & grease (FOG).

Key features:

  • Washing & compaction of screenings
  • Extraction of sand
  • Many options including FOG removal (on ICEd version)

 

Key Advantages:

  • No odours
  • Small footprint & minimal civil works
  • Low operating costs and maintenance
  • Ease of installation and operation
  • Low organic matter in the solid residue extracted
  • Reduction up to 40% in volume of solids removed
