World-class New Materials for Sewage Treatment
Adjust font size:

China has recently developed world-class high-molecular-weight polyacrylamide products which can be used for sewage treatment, paper making and oil exploitation.

The products were developed by the Changchun Research Institute of Applied Chemistry under the Chinese Academy of Sciences in Changchun, capital of northeast China's Jilin Province.

According to experts from the institute, the new materials, up to international criteria, are in conformity with the development trend of green chemistry.

The new products require simple production techniques and cause no second-time pollution.

Application tests showed that the new product dissolved in 10 minutes without floating agglomeration, which could greatly enhance the efficiency of sewage treatment and dehydration.

In recent years, local governments have attached great importance to the treatment of industrial waste water and domestic sewage. It is believed that the new materials will benefit sustainable economic growth in China.
