What is polyaluminum chloride (PAC)?

Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency and it has the widest pH and temperature application ranges compared to other water treatment chemicals.

What is the Pfaudler PAC solution?

The Pfaudler PAC Solution not only includes the Glasteel® Reactor for your PAC production, but also includes the PAC process technology and the design and supply of the entire process system. Our PAC Process Technology was developed back in the 1980’s and has been optimized over the years with our multiple plant designs and installations.

Why is PAC used in papermaking?

PAC is used in the papermaking industry to increase drainage rates in neutral and alkaline processes, as a retention aid, to increase sizing efficiency and to reduce cationic demand. In 1884, Pfaudler invented the technology of corrosion resistant, glass-lined steel (Glasteel®) and is the leader still today in this technology.

Does PAC affect pH?

PAC has very little effect on pH resulting in minimized need for pH adjustment chemicals, thus further reducing operating costs. PAC is used in the papermaking industry to increase drainage rates in neutral and alkaline processes, as a retention aid, to increase sizing efficiency and to reduce cationic demand.
