Welcome to Industrial Materials Kenya, the leading supplier of industrial chemicals across Kenya. If you are searching for Poly Aluminium Chloride (PAC)—a powerful coagulant used for water treatment, wastewater management, and industrial applications—you’ve come to the right place.
At Industrial Materials Kenya, we provide high-quality PAC, technical support, competitive pricing, and reliable supply nationwide
What Is Poly Aluminium Chloride (PAC)?
Poly Aluminium Chloride, commonly abbreviated as PAC, is a highly effective inorganic polymer coagulant used primarily in water treatment. Chemically, it is represented as Aln(OH)mCl(3n-m) and appears as a yellowish or whitish powder, flakes, or liquid solution.
PAC works by causing suspended particles, organic matter, and other impurities in water or wastewater to coagulate into larger flocs, which then settle or can be filtered easily. Compared to traditional coagulants like alum (aluminium sulphate), PAC is more efficient, requires lower doses, and produces less sludge.
Types of Poly Aluminium Chloride in Kenya
PAC comes in different forms depending on concentration, purity, and application:
A. Powdered PAC
Available in 28–30% basicity
White or yellowish fine powder
Dissolves easily in water
Ideal for municipal and industrial water treatment
B. Liquid PAC
Pre-dissolved form for easy dosing
Concentration varies from 10–30%
Reduces dust hazards and simplifies handling
Suitable for continuous dosing systems in water plants
C. Flake PAC
Hard flake form
Often used for bulk storage and slow dissolution
Stable and convenient for long-term storage

Applications of Poly Aluminium Chloride in Kenya
PAC has a wide range of applications in water treatment, industrial processes, and environmental management.
1. Municipal Water Treatment
PAC is extensively used by Kenyan water companies and municipalities to:
Remove turbidity and suspended solids
Reduce color and odor
Coagulate organic matter and bacteria
Improve water clarity and quality for drinking
Water treatment plants in Nairobi, Mombasa, Kisumu, Eldoret, Nakuru, and Thika use PAC to treat raw water from rivers, dams, and boreholes.
2. Wastewater Treatment
Industrial plants, municipal sewage plants, and factories use PAC to:
Remove solids and sludge efficiently
Reduce chemical oxygen demand (COD) and biological oxygen demand (BOD)
Treat effluents from industries like food processing, breweries, textiles, and chemicals
PAC reduces sludge volume and improves filtration efficiency compared to traditional alum.
3. Industrial Water Treatment
PAC is used in industries that require clean process water:
Boiler water treatment
Cooling water systems
Water for manufacturing processes
Pre-treatment for reverse osmosis (RO) systems
It protects machinery and improves energy efficiency.
4. Swimming Pools and Recreational Facilities
Clarifies pool water
Reduces bacterial load
Enhances chemical effectiveness in pools
5. Paper and Pulp Industry
PAC acts as a sizing agent
Improves paper strength
Reduces water consumption during processing
6. Food and Beverage Industry
PAC is sometimes used in the treatment of water for food and beverage processing plants, ensuring safety and compliance.
7. Agriculture
PAC can be used for irrigation water treatment
Reduces sediment and improves water quality for farms
Benefits of Using Poly Aluminium Chloride
High Efficiency – Requires lower doses than traditional alum
Fast Coagulation – Reduces treatment time
Less Sludge Production – Cost-effective disposal
Versatile – Works in a wide range of pH and temperature
Better Water Quality – Produces clearer, safer water
Economical – Lower consumption reduces costs
Environmentally Friendly – Reduces chemical residues and improves sludge dewatering
Application Guidelines
Water Treatment: Typical dosage ranges from 5–50 mg/L depending on turbidity
Wastewater Treatment: Dosage may vary between 10–100 mg/L
Application Method: Pre-dissolve PAC in water for uniform distribution, then add to raw water with proper mixing
Note: Always conduct jar tests or pilot trials to determine optimal dosage for specific water conditions.
Handling and Safety Measures
PAC is safe when handled properly, but it is acidic and requires precautions:
Wear gloves, goggles, and protective clothing
Avoid inhalation of powder or contact with skin and eyes
Store in a cool, dry, ventilated area away from moisture
Keep away from strong bases and incompatible chemicals
Wash hands thoroughly after handling
Packaging Options in Kenya
25kg bags (most common for powder PAC)
50kg bags (industrial use)
Drums or IBC tanks for liquid PAC
Custom bulk supply available for large water treatment plants
Industrial Materials Kenya ensures all PAC packaging protects against moisture, contamination, and spillage.
