Physical Treatment
Removal of coarse pollutants through screening, grit removal, equalisation and sedimentation stages.
Physical treatment is the first stage where suspended solids, oil-grease and coarse pollutants are removed without chemicals. The efficiency of all downstream processes depends heavily on correct sizing of this stage.
Units applied
- Coarse and fine screens (manual or automatic cleaning)
- Grit and oil traps
- Equalisation tank and mixing systems
- Primary sedimentation tanks and scrapers
- Transfer and dosing pumps
