Background
- Cooperative Customer: An industrial park sewage treatment station inSoutheast Asia
- Problem: High suspended solids in inlet water, turbidity affectingprecipitation effect and discharge standards.
- Solution: Using our industrial alum (Purity 99. 2% Min, Granule Size: 30-70Mesh) as coagulant, combined with flocculation process, with arecommended dosage of 60-90ppm.
Effect
Colloids, sediment and tiny suspended solids in water flocculateand settle quickly; the turbidity of effluent is reduced by 85%+; thesludge in the sedimentation tank is denser, which is convenient forsubsequent treatment; the operation cost is 20% lower than that ofcomposite coagulants, and the operation is simple and stable.
Status
It has been used as a routine emergency and daily auxiliary waterpurification agent in the plant for 3 years.
