Tongji University has established close ties with many universities such as the Free University of Berlin, the First University of Lyon in France, and Nanyang Technological University in Singapore, and jointly engaged in research on cutting-edge topics of water treatment pharmaceuticals. The new coagulant, decoloring agent, and biodegradable water quality stabilizer developed have been promoted and applied in Shanghai, Henan, Hebei, Shandong, Jiangsu, Anhui, Liaoning, Sichuan, Zhejiang and other places.

A variety of water treatment products have been successfully developed and industrialized, such as polyepoxysuccinic acid (production line with an annual output of 5000 tons), modified polyepoxysuccinic acid, polyaspartic acid (production line with an annual output of 1000 tons), polysilicoaluminum sulfate (production line with an annual output of 50000 tons for papermaking and drinking water treatment), polymerized ferric sulfate (annual output of 4000 tons of solids), polymerized aluminum chloride (iron), algae removal coagulant, waste water decoloring agent, special scale inhibitor for reverse osmosis, etc.
