Features

・PAC have high adsorption affinity. So, PAC have very strong aggregation performance.
・PAC could respond to sudden changes in water quality with its wide tolerance range for proper pH and injection rate. (Usually, have an optimum pH of 6 to 8)
・PAC (especially # 100W / 100H) works extremely well to remove suspension , especially in the case of high turbidity.
・PAC could reduce the amount of basic agent much more effectively compare to Aluminum Sulfate, as it consumes less basicity.
・PAC (especially # 100W / 100H) proved that the aggregation effect does not decrease significantly even with low-temperature and low basicly water in the winter. Compare to Aluminum Sulfate.
・There will not be any coloring problems with drinking water and wastewater.

Main applications
