Characteristic and application
Polyaluminium Silicate Sulfate (PASS) is a kind of flocculant for low temperature and low turbidity water treatments. In wastewater treatments, it has advantage of low dosage, fast and large flocs, quick settlement, etc. It also has a good effect on high turbidity wastewater treatments, such as dye wastewater, tannery wastewater, papermaking wastewater. Best flocculation effect is for water of pH value 7-10. CODcr removal rate is also high.
