An alumina-content enquiry should identify both the PAC designation and the actual sample supplied. This polyaluminium chloride is a cationic yellow or light yellow powder with Al2O3 content designations of 28% / 30%. Municipal and industrial water systems are the stated evaluation contexts.
Confirm which alumina designation applies to the sample
Request the current grade declaration and analysis before comparing materials. Reported effective concentration is 28–30%, but the exact sample still needs its own composition basis. Keep the confirmed grade and test report associated throughout the evaluation.
Obtain basicity as its own measured parameter
Ask for a correctly defined basicity result and the method used to obtain it. Alumina content should not be substituted for that measurement. Review both parameters against the requirements of the intended water-treatment project.
Compare material pH and system results separately
Reported material pH is 3.5–5.0, so request the preparation and measurement conditions. That value does not identify an incoming-water operating window. Describe the actual municipal or industrial stream and arrange a controlled assessment against agreed treatment targets.
- Identify the water use and applicable grade requirements.
- Review sample-linked alumina, basicity and pH reports.
- Judge the actual treatment assessment before accepting performance.
Wastewater and potable-water enquiries can require different evidence. Obtain applicable approval documents before considering potable use, and do not infer a universal dose from a grade label. Review the supplied storage instructions with the technical documents for the powder tested.
