What is polyaluminum chloride coagulant?

The use of polyaluminum chloride (PAC) can create an environment in which both aluminum and chloride exist simultaneously. The coagulant is a principle in which metal ions attach to the surface of suspended particles and then precipitate rapidly by increasing the particle size [25–33].

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

What is the difference between Alum and polyaluminium coagulants?

For water treatment applications, instead of Alum, now there are several alternative aluminium-based coagulants. Polyaluminium coagulants (PACl) consume considerably less alkalinity than Alum. Compared to Alum, PACl works effectively over a broader pH range (5.0 to 8.0).

What is poly aluminum chloride (PAC)?

Poly Aluminium Chloride, commonly abbreviated as PAC, is an inorganic polymer that belongs to the family of aluminum salts. It is a compound primarily used as a coagulant and flocculant in water treatment processes.

What is the difference between Alum and PACL coagulation?

The restabilization zone of PACl coagulation disappears at a higher final pH value than that of alum coagulation. Moreover, the charge neutralization and sweep coagulation zones of PACl are broader in the ranges of coagulant dosage (as Al) and pH value than those of alum.

What is poly Aluminium chloride India?

As a prominent member of the aluminum salts family, Poly Aluminium Chloride India, or PAC, is extensively employed in water treatment, paper production, textiles, and many other sectors.
