Description
Polyaluminium Chloride (PAC) Powder Oman Muscat– 25 kg Bag | UV Water Systems
Turbidity in raw water — caused by suspended clay particles, silt, organic matter, and colloids — is not adequately removed by sand filtration alone without coagulation pre-treatment. Colloidal particles in the 0.001–1 micron range carry negative electrostatic charges that keep them permanently suspended in water, repelling each other and resisting gravitational settling. Polyaluminium Chloride (PAC) is a highly effective inorganic coagulant that neutralises this charge, causing fine particles to aggregate into larger flocs that settle or are captured by downstream sand filters. UV Water Systems supplies PAC coagulant in 25 kg bags for water treatment operations across Muscat and the wider Sultanate of Oman.
How PAC Coagulation Works
When PAC dissolves in water, it releases pre-polymerised aluminium hydroxide species ([Al₁₃(OH)₃₂]⁷⁺) that carry strong positive charges. These species adsorb onto the surface of negatively charged colloidal particles, neutralising the charge that keeps colloids in suspension. Charge-neutralised particles collide and stick together, forming visible floc aggregates. A downstream flocculation tank or settling zone allows larger floc to settle before the clarified water enters the sand filter. PAC operates efficiently across a wide pH range (6.0–9.0), making it suitable for Oman’s variable groundwater and surface water sources without pH pre-adjustment.
Key Features and Benefits of PAC Powder Oman Muscat.
- Superior turbidity removal: PAC achieves 90–99% turbidity reduction in a single pass when correctly dosed, protecting downstream sand filters from rapid clogging and extending backwash intervals.
- Wide pH operating range: Effective from pH 6.0 to 9.0, unlike alum (aluminium sulphate) which requires narrower pH control for optimum performance. Suitable for Oman’s variable raw water pH.
- Lower sludge volume: PAC produces less sludge than conventional alum at equivalent dose rates, reducing backwash water consumption and sludge disposal requirements for sand filter operations.
- Fast floc formation: Pre-polymerised aluminium species in PAC react faster than conventional alum, reducing the required contact time and allowing more compact treatment systems.
- Powder form for easy dissolution: Dissolves readily in water at ambient temperature for preparation of 1–5% stock solutions used in metering pump dosing systems.

Applications Across Oman
PAC coagulant is used ahead of multi-media pressure filters and sand filters in Oman’s surface water treatment, agricultural irrigation water pre-treatment, and industrial process water pre-treatment systems. UV Water Systems designs complete coagulation-filtration systems for commercial and industrial clients across Muscat, including PAC dosing pumps, contact tanks, and filter vessels.
Frequently Asked Questions
How do I determine the correct PAC dose for my water? The correct dose depends on feed water turbidity, pH, alkalinity, and temperature. A jar test — adding increasing doses of PAC to water samples and observing floc formation — determines the optimum dose. UV Water Systems can carry out jar testing on your feed water in Muscat.
Can I use PAC in my swimming pool? PAC is not approved for swimming pool use in Oman. It is a pre-treatment chemical for sand filtration systems. For pool water treatment, UV Water Systems recommends pool-grade aluminium sulphate or flocculation cartridges used through the pool filter.
