SampleAvailableStorageStore in Cool, Dry and Well-Ventilated Place
Choosing a PAC sample for sewage treatment starts with identifying the exact material grade. This polyaluminium chloride is a cationic yellow or light yellow powder identified as a flocculant/coagulant. Its reported material pH is 3.5–5.0, with the preparation method still needed for comparison.
Confirm the alumina grade before setting concentration criteria
Request the exact grade declaration and current alumina analysis for the sample supplied. Confirm the reporting basis and the acceptance limit needed by the project. Do not assume that a broad content description identifies the concentration of the particular powder being evaluated.
Separate basicity from the material pH result
Obtain a correctly defined measured basicity report as its own parameter. Ask how the pH sample was prepared and tested. A reported material pH does not establish the operating range for incoming sewage or determine the treatment conditions by itself.
Make the sewage trial specific to the water stream
Describe the actual influent and the results required for acceptance. Have the appropriate technical team compare the sample through a controlled treatment assessment. Chemical identity and grade labels do not establish a universal dose or guarantee a removal result.
What is required for a potable-water enquiry?
Request the applicable grade and approval documents for the exact material before considering that use. Review them separately from the sewage-treatment trial. Keep current alumina, basicity and pH reports associated with the powder actually tested, then assess the project results and supplied storage instructions before final acceptance.
