China develops new products to treat sewage (People's Daily) Updated: 2005-10-04 10:02
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.
