Clarifiers and settlement tanks are fundamental to water and wastewater treatment, using gravity to separate suspended solids from liquids.

Types of Clarifiers

Circular Clarifiers

Center-fed circular tanks with rotating scraper arms. Ideal for municipal applications with consistent flow.

Rectangular Clarifiers

Longitudinal flow tanks with chain-and-flight or traveling bridge scrapers. Good for large installations.

Tube Settlers

Modular inclined tube systems that increase effective settling area. Used to enhance clarification efficiency.

Lamella Clarifiers

Stacked inclined plates provide high clarification capacity in compact footprint. Ideal for upgrades.

Design Considerations

• Surface overflow rate (SOR): 20-50 m³/m²/day for municipal
• Hydraulic retention time
• Solids loading rate
• Weir loading rate
• Inlet and outlet design

Key Components

• Inlet baffles for flow distribution
• Weirs and launders for effluent collection
• Scraper mechanisms for sludge removal
• Sludge collection hoppers
• Weir level adjusters
