Coagulation efficiency is a project result to be measured against a defined water stream. This industrial-designated polyaluminium chloride, or PAC, is a cationic yellow or light yellow powder. It is identified as a flocculant/coagulant for water and wastewater-treatment evaluation.
Define efficiency before comparing PAC candidates
Specify the actual water characteristics and the treatment outcomes required by the project. Agree the measurements and acceptance targets that the comparison must use. A high-efficiency description does not establish a removal percentage or guarantee the performance of an untested sample.
Confirm alumina and basicity for the supplied powder
Reported effective concentration is 28–30%, with Al2O3 content designations of 28% / 30%. Request the exact grade declaration and current alumina report. Obtain a correctly defined measured basicity result as a separate parameter before judging the material against the project's requirements.
Keep pH and dose questions tied to the trial
Reported material pH is 3.5–5.0, which needs its preparation and measurement method to be compared meaningfully. It does not establish the influent operating range. Have the appropriate technical team assess treatment conditions using the actual stream rather than assuming a universal dose.
- What documents should accompany the comparison?
- Sample-linked composition, basicity and pH reports with applicable grade documentation.
- What determines the selection?
- The controlled treatment assessment and agreed results for the intended water use.
Review potable-water qualification separately if that use is proposed. Confirm the supplied storage instructions and retain the technical reports with the exact powder tested.
