What is poly-Aluminium chloride (PAC)?

Poly-Aluminium Chloride (PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.

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.

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 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.

What is Pac water treatment chemical?

PAC water treatment chemical has a wider range of applications and is suitable for more types of water quality. 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.

Is Pac better than alum for water treatment?

Nevertheless, in the view of physical–chemical treatment, this study shows that PAC is more efficient in improving physical parameters of partially stabilized leachate and less effective in removing COD compared to alum; perhaps for this reason, PAC is increasingly recommended for water treatment where COD is not a significant concern.
