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?

Why 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.

Why is PAC used in water treatment?

PAC helps reduce the overall cost of water treatment by 15-30%. Compared to inorganic coagulants or flocculants, PAC is suited to broad water temperature including at low temperature. Water treated using PAC has fewer salts content and can be used for ion-exchange treatment. PAC contains lower corrosivity level and is easy to handle and operate.

What is the difference between polyaluminium chloride and Pac?

Polyaluminium chloride on the other hand, possesses lower doses of aluminium. It leaves a significantly fewer aluminium traces in the water, as well as sludge by-products. PAC is characterized by the degree of basification (%), which is the concentration of hydroxyl groups relative to aluminium ions.

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.
