Product Overview
Yellow Poly Aluminium Chloride (Yellow PAC) is a cost-effective inorganic polymer coagulant produced through established manufacturing processes. It helps neutralize particle charges and promotes adsorption and bridging. As a result, suspended solids, colloidal particles and some organic matter can form larger flocs, which facilitate solid-liquid separation.
Compared with conventional aluminium salts, Yellow PAC can offer efficient coagulation and good settling performance under suitable treatment conditions. In addition, its adaptability makes it a practical option for municipal sewage and general industrial wastewater treatment. However, the actual performance depends on raw-water characteristics, dosage, pH and other operating conditions.
For high-purity applications, buyers should evaluate the relevant impurity limits and regulatory requirements before selecting a grade. Therefore, we recommend reviewing our White Poly Aluminium Chloride (White PAC) for drinking-water treatment and other applications that require stricter purity control.

For detailed alumina content, basicity, water-insoluble matter and other quality indicators, please refer to the official technical documents. These records help buyers evaluate product quality and project suitability. If additional verification is necessary, our team can discuss the relevant batch COA and testing requirements.
Our quality team compares batch inspection records with the applicable product specifications. Furthermore, buyers can arrange third-party testing when their projects require independent verification.
Core Advantages of KolinSC Yellow PAC
Excellent Coagulation & Flocculation Performance
Strong charge neutralising capability effectively removes turbidity, suspended solids and colloidal contaminants. It forms compact flocs for efficient sedimentation and reduces overall chemical dosage.
Cost-Optimised for Large-Scale Projects
Competitive unit cost makes yellow PAC ideal for high-volume municipal sewage plants and mass industrial wastewater treatment, helping you lower total operational expenditure.
Broad Water-Quality Adaptability
Works stably across pH 6.0-9.0. Performs well for variable inlet water quality and tolerates normal water-temperature fluctuations.
Fast Sedimentation & Convenient Filtration
Firm floc structure accelerates settling process, lightens load on downstream filter equipment and shortens overall water-treatment cycle.
Reliable & Stable Bulk Supply
Strict raw-material inspection and finished-product sampling control minimise batch-to-batch deviation. We maintain stable stock for repeated bulk export orders.
Yellow PAC VS White PAC (Quick Selection Guide)
Cost-Effective Industrial Grade
Yellow PAC offers an economical option for municipal sewage, mining, papermaking and general industrial wastewater treatment. Its iron content and other impurity levels depend on the specific grade and manufacturing process. Therefore, buyers should compare the actual specification with their treatment requirements.
White PAC — High-Purity Grade
White PAC offers a suitable option for applications that require tighter control of iron content, colour and other impurities. For example, some drinking-water and food-related water treatment projects require stricter material specifications. However, buyers must verify the product’s test results and applicable local regulations before selecting a grade.
In short, choose PAC according to water quality, treatment targets, impurity limits and total operating cost rather than colour alone.
Main Application Fields
Municipal Wastewater Treatment
Yellow PAC can help remove suspended solids and reduce turbidity in municipal wastewater treatment. In addition, treatment plants can evaluate its performance through jar tests before determining the operating dosage.
Mining Industry Wastewater
Mining and mineral-processing operations generate wastewater containing suspended mineral particles. Yellow PAC can promote particle aggregation and support solid-liquid separation. Meanwhile, operators should verify its performance under actual process conditions, particularly for coal-washing and other mineral-processing applications.
Papermaking Industry
Papermaking wastewater may contain fibre fines, suspended solids and organic matter. Therefore, operators can evaluate Yellow PAC as a coagulant to improve solids removal and support downstream treatment.
General Industrial Wastewater Treatment
Textile, printing and dyeing, chemical and manufacturing facilities may use Yellow PAC to treat wastewater containing colloids and suspended matter. Furthermore, operators can assess its contribution to phosphorus removal when the wastewater composition and treatment process make coagulation suitable.
Available Product Grades
28% Al₂O₃ Yellow PAC
This grade provides a cost-effective option for general municipal sewage and large-volume industrial wastewater projects. Buyers should evaluate the required dosage and treatment results through preliminary testing.
29%–30% Al₂O₃ Yellow PAC
These grades contain higher alumina levels than the 28% grade. However, higher alumina content does not automatically guarantee a lower operating dosage in every application. Actual performance depends on raw-water conditions, basicity, dosage and treatment objectives.
For projects with strict drinking-water requirements, we recommend evaluating our White PAC alongside the applicable regulations and product documentation.
