Combined Screening / Grit Removal

Description and Working Principle

The compact Wastewater Treatment Plant (STU/C) is a compact plant to pre-treat sewage entering the plant at flow rates up to 200 litres/sec.

It is a completely enclosed system for an external above ground (or below grade) installation that: 

• Screens solids from the effluent 
• Lifts the screenings above the effluent level and simultaneous washes the screenings 
• De-waters the screenings which are discharged into conveniently placed skips 
• Separates sand particles / gritl 
• Lifts and de-waters the grit which is either discharged into the same skip or a separate skip 
• Optional grease removal
