Pretreatment rehabilitation

The two bar screens in operation were obsolete and required a lot of maintenance for the operators. The plant then considered replacing them with two automatic step screens, reusing the existing conveyor belt.

“ Operators spent a lot of time on maintenance ”

Replacement project

• Technology : Step screen
• Aperture lamellas : 10 mm
• Channel width: 1200 mm
• Channel depth: 1120 mm
• Capacity per screen: 500 m³/h

Benefits:

→ Adapted to the current channel size
→ Reusing the conveyor belt
→ Low head loss
→ Working on differential water level to save energy and increase lifespan of the step screens
