The Pfaudler Polyaluminum Chloride (PAC) solution

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. This high efficiency provides for increased plant capacity and lower operating costs.  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.

In 1884, Pfaudler invented the technology of corrosion resistant, glass-lined steel (Glasteel®) and is the leader still today in this technology.  Our Glasteel® Reactor Technology is required for PAC production due to the highly corrosive HCl used in the process.  Pfaudler also has Abrasion Resistant Glass (ARG) which is the perfect choice due to the abrasive nature of the alumina used in the process.  

Pfaudler’s Engineered Solutions Group, established in the 1950’s, has a team of chemical process engineers dedicated to the design complete PAC production systems.  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.  Benefits of our PAC Process Solution include:

• Reduced dosage rates compared to other water treatment chemicals
• Large flocs produced at faster rates increase settling rate and improve downstream filtration
• Good particle removal
• Reduced residual aluminum
• Good phosphorus removal
• Excellent cold water performance
• Reduced sludge volumes
• Minimal pH effect
• Optimized PAC production process for low operating expenses
• System designed with high quality components for reliable operation and long service life.
