Is It Safe to Treat Drinking Water with Polyacrylamide?
70% of the earth's area is water and 30% is land. Water is ubiquitous in people's daily life. Industry and agriculture need more water resources. However, with the development of industry and human progress, our water resources are also seriously polluted. Although the proportion of water accounts for 70%, how much water can be drinkable, even drinkable water needs to be treated.
Polyacrylamide has many advantages in water treatment. Can it also be used in drinking water treatment? Is it safe to use polyacrylamide in drinking water treatment?
Polyacrylamide is basically non-toxic. Acrylamide, the raw material for producing polyacrylamide, and some toxic metals entrapped in it have certain damage to nerves. Acrylamide is a neurotoxic agent, which can damage nerves. After poisoning, it shows signs of weakness and dyskinesia. All countries have strict requirements for the use of Polyacrylamide in drinking water treatment. According to WHO standards, the residual AM (acrylamide) content in PAM should be controlled below 0.05%, and the content in treated water should be less than 0.25ug/L, so as to meet the treatment standard of drinking water.
