Polyaluminum Chloride (PAC) is an advanced coagulant used in water treatment for clarifying drinking water and industrial wastewater. Known for its high efficiency, PAC improves water quality by removing suspended solids and organic contaminants. It is widely used in municipal water treatment, paper mills, and more.
Description
Drinking Water Grade Polyaluminum Chloride (PAC) 30% is listed as a solid PAC product for water-treatment applications. Use of a specific grade in a drinking-water process must be confirmed against the current batch COA, SDS, applicable product approvals, and local requirements.
PAC is an aluminium-based coagulant. In a suitable treatment train, it may be evaluated to support clarification by bringing suspended particles together before a downstream separation step such as sedimentation, flotation, or filtration. This page supports product review and procurement; it does not replace treatment design, regulatory approval, or site testing.
Raw-water clarification and municipal water-treatment processes where the exact grade is approved for the intended use.
Water-treatment systems where the site has confirmed compatibility with the stream, equipment, and downstream process.
Project evaluations that include representative testing, applicable regulatory review, and documented acceptance criteria.
The table below is retained as the current listed product information. Confirm the exact batch values and acceptance criteria using current issued documentation before purchase or use.
Indicator name | Solid index | |
National standard | Company standard | |
Mass fraction of alumina (as AI2O3) /% ≥ | 29 | 29.5 |
Basicity /% | 45-90 | 40-65 |
Mass fraction of insoluble matter /% ≤ | 0.1 | 0.08 |
PH(10g aqueous solution) | 3.5-5.0 | 3.5-5.0 |
Mass fraction of iron (Fe) /%≤ | 0.2 | 0.1 |
Mass fraction of arsenic (As) /% ≤ | 0.0001 | 0.0001 |
Mass fraction of lead (Pb) /% ≤ | 0.0005 | 0.0005 |
Mass fraction of cadmium (Cd) /% ≤ | 0.0001 | 0.0001 |
Mass fraction of mercury (Hg) /% ≤ | 0.00001 | 0.00001 |
Mass fraction of chromium (Cr) /% ≤ | 0.0005 | 0.0005 |
| Note: The mass fractions of insoluble matter, iron, arsenic, lead, cadmium and chromium of the products listed in the table are all calculated based on an AI2O3 content of 10.0%. When the AI2O3 content is greater than 10.0%, the actual content should be converted into a product ratio of 10.0% AI2O3 to calculate the corresponding mass fraction. This product should also comply with relevant national laws, regulations and mandatory standards. | ||
Define the water source, treatment objective, raw-water conditions, and downstream separation process.
Request the current technical data sheet, COA, SDS, and any required drinking-water or product-contact documentation for the exact grade.
Use representative jar tests, bench tests, or pilot trials to establish suitability and operating conditions.
Confirm the approved addition point, solution preparation method, and dosage through site testing and supplier guidance rather than a generic fixed concentration.
Follow the current technical guidance and SDS supplied for the exact product grade. Store sealed material in a clean, dry location and use appropriate controls for handling powders. Confirm site procedures for solution make-up, spill response, and disposal before operation.
