Polyaluminum chloride (PAC) is a pre-hydrolyzed coagulant supplied as yellow to brown liquid or powder. Its higher basicity compared to aluminum sulfate enables effective performance across pH 5–9, eliminating the narrow pH adjustment that alum demands.
Water treatment drives demand. Municipal plants and industrial facilities use it to clarify turbidity, remove organics, and destabilize colloidal particles. Lower dosage requirements than alum reduce chemical costs and sludge disposal volumes; faster floc settling shortens basin retention times.
Paper mills apply it as retention aid, fixing fine fibers and fillers to improve sheet formation and reduce raw material losses. Textile wastewater treatment adopts it for color removal from dyehouse effluent.
Liquid product stores in acid-resistant tanks or polyethylene totes; powder requires moisture-sealed packaging to prevent caking and heat-generating hydrolysis. Undiluted shelf life runs 12–18 months; prepared solutions degrade within days and require fresh preparation.
Key Performance Features
Exceptional Purity & Safety
Strictly controlled for heavy metals and insoluble matter, ensuring the highest level of safety for human consumption and sensitive food processes.
Ultra-Low Residual Aluminum
The spray-drying process ensures a more stable and balanced molecular structure, minimizing residual aluminum levels in treated water.
Instant Solubility & Clarity
The fine, uniform particles dissolve instantly in water without leaving any residue, creating a perfectly clear brine and improving dosing accuracy.
Reduced Chemical Footprint
Higher activity levels mean lower dosage requirements compared to standard grades, resulting in less chemical storage and lower sludge production.

FAQ
Q: Why is spray-dried PAC better for drinking water?
A: Spray drying provides smaller particles and lower iron content, which prevents water from turning slightly yellow and ensures better safety.
Q: Is this product compatible with existing dosing pumps?
A: Yes, its high solubility ensures it won't clog fine dosing nozzles or valves in automated systems.
Q: What is the shelf life for high-purity PAC?
A: When stored in a cool, dry place, the shelf life is 2 years from the date of manufacture.
Q: Do you offer OEM packaging?
A: Yes, we provide full OEM services, including logo printing, customized packaging design, and weight adjustment.
Q: What is your minimum order quantity (MOQ)?
A: MOQ depends on the packaging type and destination. We support flexible bulk orders for distributors and project buyers.
