Product Overview
Industrial Grade Poly Aluminium Chloride (PAC) is a widely used inorganic polymer coagulant for municipal sewage treatment, industrial wastewater clarification, and general water treatment. As a cost-effective alternative to conventional aluminium salts in many applications, it helps neutralize particle charges and promotes the formation of larger flocs.
During coagulation, PAC destabilizes suspended particles and colloids. As a result, these particles can aggregate and settle more effectively, making subsequent clarification and solid-liquid separation easier. However, actual performance depends on raw water quality, product grade, dosage, pH, and operating conditions.
KolinSC offers industrial PAC grades with different aluminium oxide (Al₂O₃) contents to meet varying treatment requirements. For example, 24–28% grades may suit general wastewater applications, while selected 29–30% grades may be considered where higher Al₂O₃ content is required. Nevertheless, a higher Al₂O₃ content does not automatically guarantee lower consumption or better treatment results.
For applications requiring stricter impurity control, buyers should evaluate the relevant product specifications and regulatory requirements before selecting a suitable grade.

The figures above represent the stated product specification range. Actual batch values should be verified against the applicable COA. Third-party testing can be discussed when required.
Available Grades — Choose by Al2O3 Content
24%—26% Al2O3 — Economy Grade
Most cost-effective option. Suitable for general municipal sewage, low-turbidity industrial wastewater and projects where budget is the primary concern.
28% Al2O3 — Standard Grade
Balanced performance and price. The most widely used grade for municipal wastewater plants and general industrial effluent treatment.
29% Al2O3 — High Performance Grade
Higher alumina content means lower dosage per cubic metre. Recommended for projects with tighter discharge limits or higher raw water turbidity.
30% Al2O3 — Premium Industrial Grade
Highest alumina content in the industrial range. Minimum dosage, maximum flocculation efficiency. Suitable for demanding industrial wastewater and large-scale projects.
These categories are preliminary purchasing references rather than guarantees of performance. In practice, the best choice depends on the water composition, required effluent quality, chemical consumption, and sludge characteristics.

Core Advantages of KolinSC Industrial PAC
Coagulation Performance for Wastewater Treatment
PAC helps destabilize suspended particles and promotes floc formation. Consequently, it can support clarification and solid-liquid separation in suitable municipal and industrial wastewater treatment processes.
However, floc size, settling speed, and final water quality vary with the water being treated. Therefore, application testing is recommended before establishing routine operating conditions.
Multiple Grades for Different Budgets
Water treatment facilities do not all have the same chemical requirements. For this reason, KolinSC offers different PAC grades to help buyers compare specifications and purchasing costs.
Although higher Al₂O₃ content may affect the amount of product required, it should not be used as the sole basis for comparing cost. Instead, evaluate the actual dosage, treatment results, pH adjustment requirements, and sludge handling costs together.
Water Solubility and Dosing Convenience
PAC powder can be dissolved in water to prepare a dosing solution. When properly prepared, this solution can be introduced through suitable chemical dosing equipment.
For best results, add the powder gradually to water under continuous mixing. In addition, allow sufficient mixing and preparation time to minimize undissolved particles and uneven concentrations. The appropriate preparation concentration and mixing conditions should be established according to the product instructions and equipment requirements.
Application Across Different pH Conditions
PAC is used in a variety of water treatment conditions. Nevertheless, the effective pH range depends on the product grade, alkalinity, water composition, and treatment objective.
Therefore, the stated application range should be treated as an initial reference rather than a universal operating limit. A controlled jar test can help identify suitable pH conditions and dosage levels for a specific wastewater stream.
Bulk Supply and Export Coordination
For treatment plants and industrial projects, reliable supply planning is essential. KolinSC supports bulk-order enquiries and coordinates product specifications, packaging, documentation, and shipment arrangements.
In addition, buyers can confirm available grades, order quantities, and estimated lead times before placing an order. This helps align purchasing decisions with project schedules and inventory requirements.
Cost Evaluation for Large-Scale Applications
For high-volume wastewater treatment, the lowest price per tonne does not always result in the lowest treatment cost. A more useful comparison considers the chemical consumption required to achieve the same treatment objective.
Accordingly, buyers should compare the cost per cubic metre of treated water, actual dosage, and relevant downstream treatment costs. This approach provides a more practical basis for evaluating PAC grades and suppliers.
