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
