What is poly Aluminium chloride (PAC)?

Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect. 1. Poly aluminium Chloride 30% – PAC S

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].

What is the optimal pH range for Pac coagulation?

The optimal pH range for PAC coagulation performance was 7.5 to 8.0. The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.

What is polyaluminium chloride 30% used for?

Polyaluminium Chloride 30% – PAC R 7) Used for waste water treatment. Poly aluminium chloride (PAC) is a kind of inorganic macromolecule flocculant. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule.

What is the treatment capacity of polyaluminium chloride?

Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing.

How PACL coagulation zones are compared with alum?

The coagulation zones at various PACl dosages and solution pH values were developed and compared with those of alum. It is found that the optimal mechanism under acidic condition is charge neutralization, while alkaline condition will facilitate the coagulation of PACl.
