Primary & Secondary Clarifier

Clarifiers are essential in wastewater treatment when suspended solids levels are high. They separate solids from liquids using the principle of gravity settling, producing clear effluent for further treatment.

Primary clarifiers remove coarse solids and organic matter, while secondary clarifiers remove biological flocs after biological treatment. Sludge is collected at the bottom, scum is removed from the surface, and coagulants/poly-electrolytes enhance settling efficiency.

✔ Gravity-based solids separation | ✔ Efficient sludge & scum removal | ✔ Enhanced flocculation | ✔ Low maintenance | ✔ Supports high flow rates
