Yellow powder appearance is only the beginning of identifying a PAC grade for a water-treatment enquiry. This industrial polyaluminium chloride is named for water-purification treatment, while the actual grade measurements still need to accompany the sample being evaluated.
Ask what the PAC analysis measures
Request the basis behind the 99.5% purity designation. It should not be read as an Al2O3 content result or substituted for a measured alumina analysis.
Obtain current Al2O3 and basicity reports with their methods. The stated formula is Al2Cl(OH)5, but a formula expression does not provide the measured grade distribution or replace the actual basicity test.
Choose a treatment assessment for the water
Identify the water stream and the target that the proposed evaluation must meet. Have the relevant technical team assess the actual powder under representative conditions and compare the results against that target.
- Define the incoming-water characteristics and acceptance measurements.
- Confirm the sample identity and current grade analysis.
- Review the controlled trial with the material documentation.
Keep industrial treatment approval specific
The industrial designation does not establish potable-water qualification. Ask for the applicable grade and approval documents if that particular use is required.
A generic purity figure also does not determine a universal dose or guarantee a removal percentage. Review the sample's composition, impurity and handling information with the actual-water results, and request separate documentation for any reagent or agricultural grade requirement.
