A potable-water enquiry begins with evidence for the exact grade being supplied. This polyaluminium chloride, or PAC, is a cationic yellow or light yellow powder identified as a flocculant/coagulant. Its stated alumina content designations are 28% / 30%, with reported effective concentration of 28–30%.
Identify the PAC grade and its intended water use
Request current analysis and confirm which alumina designation applies to the sample. For potable-water work, obtain the applicable grade and approval documents before considering use. A water-treatment name or industrial-grade description does not establish drinking-water qualification.
Ask for measured basicity and the pH method
Obtain a correctly defined basicity report for the actual material. Stated pH is 3.5–5.0, so request the solution preparation and measurement conditions behind that figure. A material pH result is not an operating window for the incoming water.
Evaluate the specific water stream and acceptance targets
Describe the water source, relevant characteristics and the treatment results that the project must achieve. Have the appropriate technical team assess the actual sample through a controlled treatment trial. The grade name and composition designations do not establish a universal dose or removal result.
Connect the documents with the sample tested
Keep the current alumina, basicity and pH reports associated with the exact powder evaluated. Review the trial results and applicable use documents together before acceptance. Confirm the supplied storage instructions, and resolve the grade identity before comparing this material with another PAC sample.
