A 30% PAC enquiry should identify the actual polyaluminium chloride grade being offered for the wastewater project. This cationic coagulant/flocculant is described as yellow to light-yellow powder, with 28% and 30% Al2O3 entries that need to be matched to the proposed material.
Resolve the actual 30% Al2O3 offer
Request current product analysis, its assay basis and the relevant impurity limits rather than treating a broader 28–30% entry as a committed 30% result. Confirm measured basicity separately, since an Al2O3 content shown under a basicity label does not establish that property.
- Product pH
- Confirm the solution concentration and method behind the reported 3.5–5.0 range.
- Water conditions
- Describe the actual influent characteristics and treatment arrangement for the industrial trial.
- Acceptance basis
- Agree the analytical endpoints and process criteria needed to judge the proposed grade.
Set a water-specific coagulant comparison
Use representative jar tests and the actual process requirements to assess clarification and downstream acceptance. Confirm whether a proposed dose is expressed as product or another basis before applying it; a chemical designation does not provide a universal operating dose or influent pH window.
Check the grade documents against the intended application
Reconcile the chemical identifiers with current technical, analysis and safety documents for the offered powder. Confirm its cool, dry and well-ventilated storage direction, and obtain separate applicable evidence for any drinking-water role rather than transferring an industrial-use designation.
For this 30% Al2O3 enquiry, approval should follow the confirmed actual composition, measured basicity and relevant water-treatment results. Keep the material specification and the plant-specific treatment assessment clearly connected.
