How is poly Aluminium chloride used in wastewater treatment?

This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed. In the context of wastewater treatment, poly aluminium chloride is used to treat both industrial and municipal wastewater, effectively reducing the load of organic matter and pollutants.

What is poly Aluminium chloride (PAC)?

In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.

Why is flocculation important in industrial wastewater treatment?

Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.

Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

What is poly Aluminium chloride used for?

In the context of wastewater treatment, poly aluminium chloride is used to treat both industrial and municipal wastewater, effectively reducing the load of organic matter and pollutants. The application of aluminium chloride is not just limited to basic water purification.

Why are polymeric flocculants used in industrial effluent treatment?

Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).
