What is PACL in water treatment?
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.
Is aluminum chloride a metal?
Aluminum chloride is a chemical compound that is used primarily in making aluminum metal, but it has other uses, as well. The compound reacts strongly in the presence of water, so it’s important to take care when handling it. Aluminum chloride is a white compound of aluminum and chloride.

What is PAC material?
PAC ( Poly Aluminum Chloride) is one of the effective fluctuant for the water treatment in waste water, drinking water, paper manufacture, mining, etc. With competitive price and high efficiency, PAC is widely used in different countries. For the Chloride (Cl-), it is mainly from the Hydrochloric Acid.
What is PACl coagulant?
Polyaluminium chloride (PACl) is a ‘coagulant’ chemical added to water to help remove small particles of dirt and contaminants that can make people sick, and block the water system’s filters.
What is polyelectrolyte used for in water treatment?
Polyelectrolytes have many applications, mostly related to modifying flow and stability properties of aqueous solutions and gels. For instance, they can be used to destabilize a colloidal suspension and to initiate flocculation (precipitation).
