Polyacrylamide, also known as PAM, is a polymer compound synthesized by polymerization reaction with acrylamide as the main monomer.It is widely used in water treatment, petroleum extraction, paper manufacturing and other fields.

The role of polyacrylamide in water treatment

In water treatment, polyacrylamide mainly acts as a flocculant and precipitant.In the common water purification process, the sewage first goes through physical treatment processes such as screens and sedimentation tanks, and then the suspended solids are condensed into large particles by adding polyacrylamide, which is conducive to precipitation and filtration, and finally clear and transparent water is obtained.

Calculate the amount of polyacrylamide required for 1 ton of water

Since the amount of polyacrylamide generally depends on the sediment content of the water, the amount of polyacrylamide required for 1 ton of water is different.Taking the treatment of agricultural sewage contaminated from land as an example, it is usually necessary to add a polyacrylamide concentration of 0.3-1g/L.Therefore, the amount of polyacrylamide required for 1 ton of water is between 300-1000 grams.

Factors of change in the amount of polyacrylamide

The amount of polyacrylamide is affected by a variety of factors.The following are a few common factors：

1.Water quality

The water quality of the water has a greater impact on the amount of polyacrylamide.If the water quality is good and there are fewer pollutants in the water, the amount of polyacrylamide will be smaller; on the contrary, if the water quality is poor and there are more pollutants in the water, the amount of polyacrylamide will increase.

2.Purpose of processing

Different treatment purposes determine the different amounts of polyacrylamide.If it is to remove suspended solids from the water, a large amount of polyacrylamide needs to be added in the early stage of water treatment; if it is to purify microorganisms and other bacteria in the water, the amount of polyacrylamide is relatively small.

3.Treatment method

Different treatment methods also have an impact on the amount of polyacrylamide.If it is a physical treatment method, more polyacrylamide needs to be used as a flocculant and precipitant; if it is a biological treatment method, the amount of polyacrylamide is relatively small.

Environmental issues of polyacrylamide

Although polyacrylamide is an environmentally friendly polymer compound, there are still certain environmental protection problems in its production and use.If it is used improperly or mishandled improperly, it may be placed in a sewage treatment system, such as filters, storage tanks, etc.This will produce secondary pollution and pollutant enrichment problems.Therefore, when polyacrylamide is applied to the water treatment process, environmental protection issues need to be fully paid attention to, and correct treatment methods and environmental protection measures should be adopted.

In water treatment, polyacrylamide is an important water purifier.How much polyacrylamide is needed for 1 ton of water depends on many factors such as water quality, treatment purpose, and treatment method.In order to avoid environmental problems, correct treatment methods and environmental protection measures need to be taken.
