Industrial Coagulants (Alum & PAC).

Rated 3 out of 5 based on 2 customer ratings

Industrial Coagulants (Alum & PAC): Aluminum Sulfate ( $\text{Al}_2(\text{SO}_4)_3$ ) & Polyaluminum Chloride (PAC).

High-Efficiency Flocculants for Water Purification & Wastewater Treatment.

High-performance inorganic coagulants engineered for raw water clarification, municipal drinking water treatment, industrial effluent processing, and paper manufacturing.

Aluminum Sulfate (Alum): Traditional, cost-effective coagulant available in liquid (8%) or solid granular/powder (17%) forms. ideal for general water clarification across standard pH ranges.
Polyaluminum Chloride (PAC): Advanced, high-charge polymeric coagulant (28%–30% $\text{Al}_2\text{O}_3$ ). Delivers rapid flocs, lower dosage requirements, minimal sludge volume, and effective operation over a wide pH and low-temperature range.

Both chemicals are packaged in heavy-duty 25kg/50kg bags, 200L drums, or 1,000L IBC tanks with full batch traceability.

Primary Applications

Aluminum Sulfate (Alum)

Municipal Water Treatment: Primary coagulant for removing suspended solids, turbidity, and organic color from raw surface water.
Pulp & Paper Industry: Functions as a sizing agent and pH controller in paper manufacturing processes.
Algae Control in Ponds/Lakes: Binds phosphorus to prevent eutrophication and algal blooms.

Polyaluminum Chloride (PAC)

High-Turbidity Water Treatment: Rapidly clarifies heavy river runoff or storm water during seasonal fluctuations.
Industrial Wastewater: Superior performance in removing heavy metals, oil-water emulsions, and complex organic dye effluents (textile, tannery, processing plants).
Cold-Water Clarification: Retains high coagulation efficiency in low-temperature winter conditions where standard alum performance drops.

Key Advantages of PAC over Traditional Alum

📉 Lower Chemical Dosage: Requires up to 30%–50% less dosage volume compared to alum for equivalent clarification.
🧪 Alkalinity Preservation: Consumes significantly less alkalinity, reducing or eliminating the need for post-treatment lime or sodium hydroxide addition.
📦 Reduced Transport & Handling Costs: Higher concentration ( $\text{Al}_2\text{O}_3$ ) means lower overall freight weights and smaller storage footprint requirements.

Safety, Handling & Storage Guidelines

⚠️ Handling Advisory: Both chemicals are acidic in aqueous solutions. Contact can cause mild to moderate skin irritation and eye damage. Acidic liquids cause corrosion to mild steel and galvanized metals.

Storage Conditions: Store in dry, cool, well-ventilated areas. Keep bags sealed to prevent moisture absorption (caking). Use plastic, rubber-lined, or stainless steel (316) tanks and piping for liquid preparations.
Incompatibility: Do not mix directly with alkaline chemicals (like caustic soda or lime) in concentrated form as violent precipitation will occur.
Recommended PPE: Chemical safety goggles, dust mask (for powder handling), nitrile/PVC gloves, and protective workwear.
