By 2006, China's annual production capacity and output of polyacrylamide had reached 500,000 tons per year and 32 tons per year respectively. The apparent consumption of polyacrylamide in the country was approximately 317,700 tons that year. Among this, oil extraction accounted for about 78.5% of total consumption, followed by water treatment at around 11%, while textiles and other sectors consumed roughly 2.7%.
Polyacrylamide is widely used as a flocculant in water treatment, helping to remove suspended particles from tap water, and as a dewatering agent in sewage treatment. It also plays a key role in industrial water treatment. Many cities across China use it during periods of water shortage or poor water quality. In wastewater treatment, polyacrylamide has become the primary flocculant. In 2006, about 35,000 tons were consumed in water treatment applications.
In the paper industry, polyacrylamide serves as a retention agent. As one of the world’s largest paper producers and consumers, China used approximately 25,000 tons of polyacrylamide in the paper industry in 2006. It is projected that demand in this sector will rise to about 40,000 tons by 2010. Currently, anionic polyacrylamide dominates the market, with cationic types accounting for only around 10%, and most of them are of low quality. This has become a major constraint on the development of China's water treatment and paper industries. Consequently, many paper mills import large quantities of polyacrylamide from Taiwan, Japan, and other regions. From 2002 to 2006, the average annual growth rate of polyacrylamide imports was about 15%, reaching 26,200 tons in 2006.
Looking ahead, the application of polyacrylamide in water treatment is expected to grow as water shortages expand and national demand for clean drinking water increases. Globally, polyacrylamide accounts for 37% of total consumption, but in China, it's only around 11%, indicating significant room for growth. With the acceleration of water pollution control projects, the demand for polyacrylamide is likely to continue rising, reaching an estimated 48,000 tons by 2010.
In the paper industry, increased investment by Japanese companies like Arakawa Chemical, Seiko PMC, and Harima Chemical in China may reduce import volumes. By 2010, polyacrylamide imports are expected to drop to about 20,000 tons. Meanwhile, the petroleum industry is focusing on developing ultra-high molecular weight polyacrylamide. Field tests at Daqing Oil Field have shown that injecting one ton of this material can recover 150 to 200 tons of crude oil. With the push for tertiary oil recovery, offshore exploration, and environmental protection policies, the demand for ultra-high molecular weight polyacrylamide in urban sewage and industrial wastewater treatment is becoming increasingly urgent. As a result, the Chinese government has prioritized the development of ultra-high molecular weight polyacrylamide as a key high-tech industrial project.
