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.
