In modern industrial and municipal water treatment, the process of coagulation and flocculation is the primary defense line against suspended particulate matter, colloids, and heavy organic loads. Historically, simple metal salts like aluminum sulfate (alum) and ferric chloride were the global benchmarks. However, the operational parameters of these monomeric chemicals are highly constrained by pH fluctuations, high dosage requirements, and excessive chemical sludge generation.
To overcome these limitations, Poly Aluminium Sulphate (PAS) and its structural counterparts, such as Poly Aluminium Chloride (PAC), Aluminum Chlorohydrate (ACH), and Polymeric Aluminium Ferric Chloride (PAFC), were developed. These pre-hydrolyzed polymeric inorganic coagulants feature high charge densities, macromolecular networks, and structural stability across a broad pH spectrum.
Unlike raw alum, Poly Aluminium Sulphate ($\text{Al}_x\text{(OH)}_y(\text{SO}_4)_z$) features pre-formed polymeric species. During chemical manufacturing, the basicity of the solution is adjusted, yielding highly cationic polymeric aluminum complexes such as $\text{Al}_{13}$ and $\text{Al}_{30}$ structures. When introduced into raw turbid waters, these poly-cationic networks interact via two primary mechanisms:
| Chemical Class | Al₂O₃ Content (%) | Basicity (%) | pH Range | Primary Industry Target |
|---|---|---|---|---|
| Poly Aluminium Sulphate (PAS) | 15% - 17% | 40% - 65% | 5.5 - 8.5 | Drinking Water, Paper Sizing, Heavy Metallurgy |
| High Purity PAC (PAC-01) | 29% - 30% | 60% - 85% | 5.0 - 9.0 | Food Processing, Biological Sewage, Potable Water |
| Aluminum Chlorohydrate (ACH) | 23% - 24% | 83% - 85% | 5.5 - 9.5 | Cosmetics, High-tech Manufacturing, Municipal Sludge |
| PAFC (Al-Fe Composite) | 26% - 28% | 50% - 80% | 6.0 - 9.0 | Heavy Coal Slurry, Oily Oilfield Effluents, Dyestuff |
Purchasing directors and system engineers from water engineering companies evaluate coagulant suppliers using three criteria: Active Ingredient Concentration, Residual Heavy Metal Profile, and Logistical Redundancy. Wuxi BS operates high-throughput spray drying towers and continuous liquid reactors, ensuring every batch conforms strictly to AWWA B408 and EN 17034 specifications.
Our raw material sourcing of high-purity bauxite and hydrochloric/sulfuric acid runs on closed-loop, digital industrial control lines. This integration eliminates the risk of trace heavy metal contamination (such as Arsenic, Cadmium, and Lead) in the final product. Our materials are completely safe for food, municipal water, and critical pharmaceutical pre-treatment systems.

Direct answers from our senior research chemists and industrial engineers regarding compound properties, dosing, and bulk sourcing.
Answer: While both are pre-hydrolyzed aluminum coagulants, Poly Aluminium Sulphate uses sulfate ions ($\text{SO}_4^{2-}$) rather than chloride ions ($\text{Cl}^-$) to build its polymer network. The divalent sulfate ions create wider, heavier flocs that settle faster in low-temperature or low-turbidity waters. Additionally, using sulfate reduces chloride corrosion risks in industrial equipment and boilers.
Answer: Basicity indicates the degree of pre-polymerization (hydroxyl concentration relative to aluminum content). Higher basicity, such as in ACH (83%-85%), means more polymerized cationic aluminum species are present. This provides stronger charge neutralization, consumes less water alkalinity, and minimizes pH drops during treatment, reducing the need for secondary pH adjustment chemicals.
Answer: Yes, but dosing control is vital. Coagulants must be fully reacted and settled out in clarification basins before water reaches reverse osmosis systems. Any residual unreacted aluminum can coat and foul the membranes. Wuxi BS helps design proper dosage configurations and recommends combining inorganic coagulants with organic flocculants to prevent downstream membrane fouling.
Answer: Low water temperatures (under 5°C) slow down the hydrolysis rate of traditional monomeric salts like alum. Pre-hydrolyzed chemicals like Wuxi BS Poly Aluminium Sulphate or PAFC bypass this temperature dependency, maintaining rapid floc formation and settling rates in cold weather conditions.
Answer: For solid powders, we offer standard 25kg PP/PE woven bags with inner liners, as well as 1000kg bulk containers (Jumbo Bags). Liquid formulations are shipped in 250kg drums, 1250kg IBC tanks, or directly via bulk tank trucks, tailored to your site's handling requirements.
