Polyaluminium Chloride (PAC): Poly-aluminium Chloride, short for PAC, is a new type high performance inorganic macromolecule flocculating agent.It is mainly used in purify of drinking water and treatment of industry waste water, such as the radioactive material, leady (Pb++) chromate (Cr+++) high toxicity heavy metal and fluoride (F) waste water. Furthermore, it also widely used in precision casting, papermaking, tanning and some other fields.

Polyaluminum Chloride (PAC) compounds were developed to provide better performance than alum could offer. While they accomplished this goal, they also provide additional cost benefits when compared to alum.
PAC has a minimal impact on pH and therefore minimized the need to feed adjustment chemicals. And it is able to do a better job while using 30-60% less aluminum on average. This translates roughly to a similar percent reduction in the amount of sludge produced.
Polyaluminum Chloride (PAC) has been very impressive. In many areas where PAC has been marketed for a reasonable time period it has replaced over 75% of the total alum demand.
PAC was developed, inorganic polymers, which aided the coagulation process, were also introduced to the water treatment industry. These polymers were generally not effective as primary coagulants but when used in conjunction with aluminum, helped to improve overall performance.
