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 polyaluminum chloride coagulant?

1. Introduction Polyaluminum chloride (PAC) coagulant has been developed and used in water and wastewater treatment since the 1980s throughout the world (Jiang, 2001). PAC is made by partial hydrolysis of acid aluminum chloride solution using a specific reactor.

What is poly Aluminium chloride (PAC)?

PAC is a range of versatile inorganic polymers, and it is characterized by strength & basicity. Poly aluminium chloride has more advantages than traditional coagulants, like alum or iron salts. It is pre-neutralized & has a charged density higher than traditional. In industry and municipal use for water treatment & purification process.

What is PACs coagulant?

PACS is a specialized coagulant used widely for wastewater treatment. The medium high basicity makes PACS a superior coagulant compared to other inorganic coagulants. It is a efficient coagulant for clarification of water (i.e. turbidity/suspended solids removal), with low generation of waste sludge.

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.

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.
