Premium Polyaluminium Chloride (PAC)
Premium Polyaluminium Chloride (PAC): Advanced Water Treatment Solution
Polyaluminium Chloride (PAC) is a highly efficient, versatile inorganic polymer coagulant widely used in municipal water purification, industrial wastewater treatment, and the paper-making industry. Represented by the general formula $[Al_2(OH)_nCl_{6-n}]_m$, our PAC offers superior flocculation performance, rapid settling times, and operates effectively across a broad pH range compared to traditional coagulants like aluminum sulfate. At Hober Tejarat Pasargad, we supply high-purity PAC tailored to meet stringent environmental and health standards.
Our PAC Product Grades
We provide different grades of PAC based on the $Al_2O_3$ content (ranging from $28\%$ to $32\%$) and application requirements:
1. Drinking Water Grade (High Purity)
Characterized by a light yellow or white powder form, this grade contains $30\% – 32\%$ $Al_2O_3$. It is manufactured under strict quality controls to ensure ultra-low heavy metal content, making it perfectly safe and highly efficient for municipal potable water treatment and sizing in the paper industry.
2. Industrial Wastewater Grade
Typically pale yellow to brown in color with an $Al_2O_3$ content of $28\% – 30\%$. This highly cost-effective grade is engineered for treating complex industrial effluents, including textile dyeing wastewater, printing, tannery, and mining water runoff. It excels in COD/BOD reduction and color removal.
Technical Advantages & Packaging
- High Coagulation Efficiency: Forms large, dense flocs rapidly, resulting in faster sedimentation and lower dosage requirements compared to traditional alum.
- Broad pH Adaptability: Maintains excellent performance across a wide pH range ($5.0 – 9.0$), reducing the need for alkaline additives.
- Standardized Packaging: Supplied in $25 \text{kg}$ PP/PE woven bags with double inner plastic liners to prevent moisture absorption, or $1000 \text{kg}$ Jumbo bags for bulk handling.
- Quality Certified: All shipments come with a comprehensive Certificate of Analysis (CoA) and Material Safety Data Sheet (MSDS).

Frequently Asked Questions
What is the difference between white PAC and yellow PAC?
White PAC has the highest purity (up to $32\%$ $Al_2O_3$) and is entirely iron-free, used for drinking water and premium paper sizing. Yellow PAC contains trace amounts of iron and is utilized for general drinking water and industrial wastewater treatment.
How should Polyaluminium Chloride be stored?
PAC is hygroscopic and should be stored in a cool, dry, and well-ventilated warehouse. It must be kept away from direct sunlight, moisture, and incompatible materials like strong alkalis. Its typical shelf life is $12$ to $24$ months when stored correctly.
Do you provide MSDS and application guidance?
Yes, we provide full technical documentation, including MSDS and CoA, prior to shipment. We also offer standard guidelines on dosing and dilution ratios based on your specific water parameters.
