(PAC)
Polyaluminium chloride (PAC) is a highly effective inorganic coagulant widely used in water and wastewater treatment. It is produced in various purity grades, ranging from industrial-grade (10–30% Al₂O₃) to high-purity grades (≥31% Al₂O₃) suitable for potable water applications. PAC is valued for its high flocculation efficiency, low sludge production, and rapid coagulation, making it a preferred choice over traditional coagulants such as alum or ferric chloride.
PAC is typically supplied in liquid and solid forms. Liquid PAC is yellow to light brown, viscous, and clear, while solid PAC is usually powder or granular, easily soluble in water. The physical properties ensure consistent performance from production to application. Analytical parameters including Al₂O₃ content, basicity, pH, and density are strictly monitored to maintain quality and efficiency.
PAC production follows ISO, ASTM, and local water treatment standards, ensuring reliable chemical composition, purity, and performance. Each batch undergoes quality control tests for aluminium content, basicity, chloride concentration, and absence of heavy metals. Certificates of Analysis (COA) are provided to guarantee compliance with industrial and potable water requirements.
PAC has a broad spectrum of applications, primarily in water and wastewater treatment, but also in other industries:
Drinking Water Treatment:
Efficient removal of turbidity, colloids, and organic matter.
Wastewater Treatment:
Used for municipal, industrial, and textile effluents, reducing sludge volume and improving water clarity.
Paper & Pulp Industry:
Applied as a sizing and retention aid.
Textile Industry:
Used for dyeing, wastewater treatment, and color removal.
Chemical Industry:
Functions as a flocculant in various chemical processes.
Swimming Pools & Recreational Water:
Maintains hygienic water conditions by removing suspended solids and microorganisms.

PAC is available in 250–1000 kg IBC containers, drums, and bulk liquid tanks for liquid forms, and in 20–50 kg bags for solid forms. Packaging is designed to protect the product from moisture, contamination, and degradation during storage and transport. Proper packaging ensures safe handling and preserves product performance.
PAC is non-toxic and generally safe under proper handling conditions but is strongly acidic in concentrated forms, which may cause skin or eye irritation. Use of personal protective equipment (PPE) including gloves, goggles, and protective clothing is recommended. Spills should be contained and neutralized. PAC is environmentally friendly when used according to guidelines, and its application in water treatment produces minimal sludge compared to traditional coagulants.
PAC should be stored in cool, dry, and well-ventilated areas, away from direct sunlight and incompatible chemicals. Liquid PAC must be kept in corrosion-resistant tanks, while solid PAC should be stored in sealed, moisture-proof containers. Proper storage ensures chemical stability, maintains flocculation efficiency, and guarantees long shelf life.
Polyaluminium chloride (PAC) is an essential coagulant for water purification, wastewater treatment, and various industrial processes. With multiple grades, standardized production, and strict quality control, it provides reliable, efficient, and environmentally responsible solutions for industries worldwide. Correct handling, storage, and safety protocols maximize its performance and sustainability, making PAC a preferred choice for municipalities and industrial clients alike.
