Polyaluminum Chloride

Polyaluminim Chloride

Clearwater supplies a wide range of polyaluminum chlorides (PACl) in liquid form (KEMIRA PAX). The highly charged Al in the products is optimized for best performance for the different basicity of PACl.  The low to medium basicity products are excellent at reducing particles while maintaining good phosphorus removal properties. These are products in the range of 25 to 45% basicity (OH/Al ratio of 0.75 to 1.35) and are effective coagulants for treatment of both drinking water and wastewater. Clearwater supplies these in both Bulk Loads and IBC’s

Clearwater’s PAX is a high basicity polyaluminum chlorides (up to 70% or OH/Al ratio 2.10) have further been optimized for particle removal properties by controlling the formation of Al species in the products. Additional benefits are reduced sludge production, minimized pH adjustment, improved filter operation and an excellent performance in cold-water applications.
