Poly Aluminium Chloride is an acidic solution. It has the molecular formula Aln(OH)mCl3n-m. Classified as corrosive at higher concentrations, it is typically yellow in colour, it is miscible with water at all concentrations. It is not a single product, but a spectrum of polymers which are characterised by their strength (usually in % Al2O3) and basicity. This product is suited to a wide range of industrial applications, The main uses of Poly Aluminium Chloride fall under water treatment. It is used as a coagulant in drinking water treatment, A flocculant in the purification of water and in the treating of potable and waste water. as a coagulant and precipitant in waste water treatment, effluent treatment. clarification and as a filtration aid in swimming pool water treatment It is also used largely within the paper and pulp industry.

What is poly aluminium chloride used for?
Poly aluminium chloride (also spelled polyaluminum chloride, and widely known simply as PAC) is a high-efficiency coagulant used to remove suspended solids, phosphates and colour from water. Compared with traditional aluminium sulphate, PAC works across a wider pH range, produces less sludge and performs well in cold water.
- Drinking water and potable water treatment
- Swimming pool clarification — keeps commercial pool water polished and reduces filter load
- Industrial effluent and wastewater treatment
- Paper manufacturing and sizing
Specification and pack sizes
Supplied as an 18% aqueous solution. Available in 25L polys and 205L drums for higher-volume users. Bulk and repeat-order pricing available on request.
Handling and safety
PAC solution is mildly corrosive. Wear gloves and eye protection when handling, store in the original closed container away from alkalis, and rinse splashes with plenty of water. A full safety data sheet (SDS) is available on request.
Frequently asked questions
Is PAC better than aluminium sulphate (alum)?
For most applications, yes. PAC coagulates faster, works over a broader pH range and leaves less residual aluminium, which usually means better results with a lower dose.
What dose rate should I use?
Typical dose rates run from 10–100 ppm depending on turbidity and application. Jar testing is the reliable way to establish the right dose for your water.
Can I use PAC in a swimming pool?
Yes — PAC is widely used as a pool flocculant to restore clarity. Dose ahead of the filter in line with your pool volume and turnover rate.
