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.

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 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.

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.

Is Pac better than aluminum sulfate & aluminum chloride for removing turbidity & nom?

Moreover, the performance of synthesized PAC was also very much higher as compared with aluminum sulfate and aluminum chloride for removing turbidity and NOM from synthetic water samples. The coagulant dose and the lime required of synthesized PAC were reduced more than two folds relative to aluminum sulfate and aluminum chloride doses.

What are the synthesis parameters of aluminum chloride hexahydrate?

The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
