Poly Aluminium Chloride (PAC) is an advanced inorganic polymer coagulant with the general formula [Al₂(OH)ₙCl₆₋ₙ]ₘ. It is produced through controlled reaction of aluminium hydroxide with hydrochloric acid, resulting in a pre-polymerized species with higher charge density and molecular weight than conventional aluminium sulfate (alum). This unique structure gives PAC superior coagulation performance — rapid floc formation, wide effective pH range (5.0-9.0), and excellent removal of suspended solids, turbidity, organic matter, and heavy metals.
Moon Bright Resources supplies high-quality PAC in multiple basicity grades (30-70%) and physical forms — powder, granular, and liquid concentrate. Our product meets drinking water and industrial wastewater treatment standards, making it suitable for municipal water plants, industrial effluent treatment, and process water clarification. We offer flexible packaging from 25 kg bags to bulk tankers, with full documentation including Certificate of Analysis and Safety Data Sheets. poly aluminium chloride price per ton , poly aluminium chloride bulk supplier price

FAQ – Frequently Asked Questions
Q1: What is the advantage of Poly Aluminium Chloride over alum for water treatment?
A1: PAC offers several significant advantages over traditional alum: (1) effective over a wider pH range (5.0-9.0 vs 6.0-8.0), reducing the need for pH adjustment chemicals; (2) requires 30-50% lower dosage for equivalent turbidity removal; (3) produces larger, stronger flocs that settle faster; (4) generates 40-60% less sludge volume; (5) leaves lower residual aluminium in treated water; (6) performs better in cold water conditions (below 10°C). While PAC has a higher per-ton price than alum, the total treatment cost is typically lower due to reduced dosage, less sludge disposal, and fewer chemical adjustments.

Q2: How do I select the correct PAC basicity and form for my application?
A2: Basicity affects coagulation performance. Low basicity (30-40%) is suitable for cold water treatment. Medium basicity (40-50%) is the standard choice for most water and wastewater applications. High basicity (60-70%) is premium grade offering superior organic removal, lower sludge, and better performance on difficult-to-treat waters. For form selection: powder dissolves fastest and is ideal for dry feed systems; granular has less dust and is suitable for gravity-fed systems; liquid is ready to use but more expensive to transport.

Q4: What is your minimum order quantity (MOQ)?
A4: MOQ is 25 kg (one bag) for powder/granular sample orders, 200 L (one drum) for liquid sample orders. Small commercial orders start at 500 kg for solid forms or 1000 L for liquid. Wholesale pricing begins at 10 metric tons for solid forms and 5 metric tons for liquid. For OEM private label orders, MOQ is 10 metric tons. Full container loads (typically 20-25 metric tons for solid, 15-20 metric tons for liquid) receive maximum discount. Poly Aluminium Chloride , poly aluminium chloride supplier
Q5: How should Poly Aluminium Chloride be stored and handled?
A5: PAC is mildly corrosive and should be stored in original tightly sealed containers (solid forms) or in HDPE/FRP tanks (liquid) in a cool, dry, well-ventilated area away from direct sunlight, moisture, and incompatible materials (strong alkalis). Solid PAC is hygroscopic — exposure to moisture causes caking. Liquid PAC should be stored at 5-30°C; freezing causes degradation, and high temperatures accelerate hydrolysis. Use PPE including rubber gloves, safety goggles, and dust mask (for solids). Shelf life is 12-24 months for solids (if kept dry) and 6-12 months for liquids depending on storage conditions. We provide Safety Data Sheets (SDS) with every shipment. Poly Aluminium Chloride
