Lamella Clarifier
Mit Water manufactures lamella clarifiers (inclined plate settlers) for efficient solid-liquid separation in water and wastewater treatment. Compared to conventional sedimentation tanks, lamella clarifiers achieve a significantly smaller footprint by using inclined parallel plates that increase the effective settling area by a factor of 6 to 15.
Working Principle
Feed water enters the clarifier and flows upward through a pack of inclined parallel plates spaced at 50 to 80 mm intervals. Suspended solids settle onto the plate surfaces and slide down by gravity into a sludge collection hopper at the bottom, while clarified water overflows through weirs at the top. The inclined plate design provides a large settling surface within a compact volume.
System Features
Our lamella clarifiers include an inlet distribution zone, inclined plate pack (PP, PVC or SS304), sludge hopper with scraper mechanism, clarified water collection trough, and a support structure. The system is usually preceded by coagulation and flocculation tanks for optimal performance.
Lamella clarifiers are widely used for efficient solid-liquid separation:
- Industrial wastewater pre-treatment and primary clarification
- Surface water treatment for drinking water production
- Post-precipitation clarification for heavy metal removal
- Chemical softening sludge separation (lime softening)
- Mining and mineral processing water clarification
- FGD wastewater treatment in power plants
- Backwash water recovery from filtration processes
