What are the types of organic polymer flocculants?

Organic polymer flocculants are divided into two categories: natural polymer and synthetic polymer. From the chemical structure, it can be divided into the following three types: (1) Polyamine type-low molecular weight cationic electrolyte; (2) Quaternary ammonium type-wide range of molecular weight and high cationicity;

Which flocculant is used in domestic water treatment?

The most widely used flocculant in domestic water treatment is a series of synthetic polyacrylamide products, mainly divided into anionic, cationic, nonionic and zwitterionic.

Why should we use Pam instead of inorganic flocculant?

In treatment, using organic flocculant PAM instead of inorganic flocculant, the water purification capacity can be increased by more than 20% even if the sedimentation tank is not reformed. So at present, many large and medium-sized cities in the water supply shortage or poor water quality, are using PAM as a supplement.

How is organic polymer flocculant made?

It is made by grafting (or copolymerizing) natural raw materials and polyacrylamide. Organic polymer flocculants are divided into two categories: natural polymer and synthetic polymer. From the chemical structure, it can be divided into the following three types: (1) Polyamine type-low molecular weight cationic electrolyte;

What are non ionic organic polymer flocculants?

Non-ionic organic polymer flocculants are mainly polyacrylamide. It is obtained by polymerization of acrylamide. Polymers such as polyacrylic acid, sodium polyacrylate, calcium polyacrylate, and alkali hydrolyzate of polyacrylamide. Copolymers of styrene sulfonate, lignosulfonate, acrylic acid and methacrylic acid.

What are the advantages and disadvantages of inorganic flocculants?

The advantages of inorganic flocculants are relatively economical and simple to use; but they are large in dosage, low in flocculation effect, and have the disadvantages of high cost and strong corrosiveness. Organic polymer flocculant is a new type of wastewater treatment agent developed in the late 1960s.
