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.

How to use polyaluminium chloride PAC coagulant in sewage treatment process?

Most industries need to use polyaluminium chloride PAC chemical in the sewage treatment process. The precipitation rate of PAC chemical is much faster and the precipitation effect is better. The use method of PAC coagulant is to dissolve it in a certain proportion and then add it to water.

How many types of polyaluminium chloride are there?

There are four types of polyaluminium chloride for sale with different content of AL2O3 and basicity. Among them, PAC 30% 01&02 is used for drinking water treatment, while PAC 30% 03&PAC 28% 04 is used for industrial wastewater treatment. The four types can be easily distinguished by color, from white, light-yellow to deep-yellow.

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.

How does polyaluminium chloride affect wastewater treatment equipment?

After the use of Polyaluminium Chloride (PAS), the content of iron, manganese and other heavy metals in water is lowered, which has a little corrosive effect on wastewater treatment equipment.

What is polyaluminium chloride?

Polyaluminium chloride, also written as poly aluminium chloride, is an inorganic polymer coagulant used for water treatment. Take the first letter of words as abbreviation, it is refered to as PAC chemicals, can be considered as one of the best coagulants.
