Coagulation. Some of the common poly aluminum chloride uses are the removal of anionic colloidal impurities and settling of suspended materials during clarification of drinking water, sewage and industrial effluents.
- Using PAC as flocculant, the speed of flocs forming and settling is quick. Flocs formed is easy to filter
- Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better.
- It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9
