A municipal water-treatment plant enquiry must identify the actual water stream and the grade evidence required for that role. This polyaluminium chloride, or PAC, is a yellow to light-yellow cationic coagulant/flocculant powder, with a 30% Al2O3 grade request still to confirm against the offered material.
Define the municipal stream and required grade evidence
Specify the treatment arrangement, influent characteristics and analytical acceptance targets relevant to the plant. If the intended role concerns drinking water, obtain the separate applicable grade and approval documents rather than inferring qualification from a municipal-use or ISO label.
Resolve composition and basicity before comparing grades
Reconcile the 30% enquiry with the 28% and 30% Al2O3 entries and request a clear actual content commitment with current analysis. Measured basicity and impurity limits need their own evidence; an Al2O3 content shown under basicity is not a measured basicity result.
- Product pH
- Confirm the solution concentration and method for the reported 3.5–5.0 range.
- Plant trial
- Agree representative jar tests, actual dose basis and the relevant process acceptance criteria.
- Document verification
- Obtain current technical and safety documents and any applicable ISO certification with its actual scope.
Keep product descriptors separate from treatment outcomes
The product pH does not define an influent operating window, and a cationic designation does not establish removal performance or an operating dose. Confirm the cool, dry and well-ventilated storage direction and assess the actual offered grade through water-specific results.
For this municipal PAC enquiry, let confirmed composition, basicity and applicable grade evidence define the material. The plant's representative tests and agreed endpoints should determine acceptance for its actual treatment role.
