Product Description
Polyaluminum Chloride (PAC) is a highly effective coagulant widely used in water and wastewater treatment due to its efficiency, cost-effectiveness, and versatility. Below are its key applications:
1. Drinking Water TreatmentRemoves turbidity, suspended solids, and organic matter.
Effective in color and algae removal.
Works over a wide pH range compared to traditional coagulants like alum (aluminum sulfate).
2. Wastewater TreatmentMunicipal wastewater: Clarifies sewage by removing phosphates, heavy metals, and colloidal particles.
Industrial wastewater: Treats effluents from textiles, paper mills, tanneries, and chemical plants.
Reduces COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand).
3. Sludge DewateringEnhances sludge thickening and dewatering in sewage plants, reducing disposal costs.
4. Oil-Water SeparationUsed in petroleum, food processing, and metalworking industries to break oil-water emulsions.
5. Paper & Pulp IndustryImproves retention and drainage in papermaking.
Reduces wastewater load from paper mills.
6. Textile IndustryRemoves dyes and sizing agents from wastewater.
7. Mining & Mineral ProcessingClarifies mine drainage water and aids in tailings treatment.
Advantages of PAC Over Traditional Coagulants (e.g., Alum, Ferric Chloride)✔ Wider pH range (works well at pH 5–9).
✔ Lower sludge production.
✔ Faster floc formation & better settling.
✔ Less corrosive than ferric-based coagulants.
✔ More effective in cold water.
LimitationsAluminum residual concerns (linked to health risks if not properly removed).
Costlier than alum but often more economical due to lower dosing requirements.
