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 .

What is poly aluminum chloride?

Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants.

What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants. PAC is available in both liquid and powder forms and is known for its ability to perform effectively over a wide pH range.

What coagulants are used in drilling fluids?

Drilling fluids used in the oil industry produce a lot of effluents that require proper treatment before their disposal. Efficient coagulants/flocculants can reduce the bulk of disposed of pollutants into the hydrosphere. Polyacrylamide-based artificial polymers are efficient flocculants for industrial effluents.

How does poly Aluminium chloride work?

It works by destabilising and aggregating particles, making it easier to remove them through sedimentation or filtration. Poly Aluminium Chloride is preferred in many water treatment applications due to its quick reaction time, reduced sludge production, and the ability to operate efficiently in cold temperatures.

Can polymeric PAC be used for water treatment?

Several researchers have investigated the synthesis, of PAC and its performance for water treatment. The results shows that various polymeric species of PAC yield (Al b species) are obtained and different performance efficiencies for water treatment are reported in the literature [21, 24].
