Poly Aluminium Chloride in Water Treatment: A Clear Solution ...
Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9.

Get PriceWhy is poly Aluminium chloride used in water treatment?
The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
What is poly Aluminium chloride used for?
Ultimately, this results in clear water ready for safe discharge or further treatment. Drinking Water Treatment: Poly Aluminium Chloride is commonly used to treat raw water from rivers, lakes, or wells. It effectively removes turbidity, microorganisms, and dissolved organic matter, ensuring that the water is safe to drink.
Is polyaluminium chloride a safe coagulant?
Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.
How effective is aluminium chloride in water treatment?
Composed of multiple aluminium and chloride ions, it has proven highly effective in clumping unwanted materials and sediments in water. The unique properties of aluminium chloride allow it to function efficiently across a broad range of pH levels, making it a versatile choice for various water treatment scenarios.
What is poly Aluminium chloride (PAC)?
Poly Aluminium Chloride (PAC) has emerged as a valuable and versatile tool in water treatment processes, it plays a crucial role in making water safe for consumption, industrial use, and environmental preservation. Why we use Poly Aluminium Chloride (PAC) for water treatment?
What is polyaluminium chloride?
Polyaluminium chloride is the one of the first chemicals that are added in the water during the coagulation process. The compound is highly charged, where it reacts and neutralizes the negative charge on dirt and other dissolved particles. This will allow the compound to bind together to form larger particles.
