What is polyaluminium chloride (PAC)?

Polyaluminium chloride (PAC) is a widely used water treatment chemical. It has a wide range of PH adaptation and it is not easy to produce color or other side effects. After the use of poly aluminum chloride, the content of iron, manganese and other heavy metals in water is low, which has a little corrosive effect on the equipment.

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

Does PAC coagulate?

PAC acts primarily as a coagulant, helping in the aggregation of suspended particles into larger clumps that can be easily settled or filtered from water. Is poly aluminium chloride hazardous?

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.

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.

What is polyaluminium chloride used for?

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
