Polyaluminum Chloride is not a single product, but an entire spectrum of versatile inorganic polymers. Polyaluminum Chloride is not a single product, but an entire spectrum of versatile inorganic polymers. 
Polyaluminum Chloride (PAC) can offer a number of advantages over traditional coagulants such as alum or iron salts. Because Polyaluminum Chloride's are pre-neutralized and have a higher charge density than traditional coagulants, they coagulate via a more efficient mechanism, called charge neutralization. This allows Polyaluminum Chloride's to be effective at lower doses than alum or iron salts, when one compares the actual metal being added by the coagulant to the system. Resulting benefits can include:
1. Less pH depression and alkalinity depletion, reducing lime or caustic requirements
2. Reduced chemical sludge volumes.
3. Sludge density is increased.
4. Improved results in higher pH systems.
5. Better performance in cold water.
And because PAC does function so differently, there are many applications where it will provide finished water quality that the traditional coagulants can't achieve.
