The Shanghai Bailonggang Wastewater Treatment Plant is the largest sewage treatment plant in Asia and one of the largest in the world.

For the expansion of the facility, which also includes the introduction of more advanced water treatment processes, it was decided to rely on the experience and proven effectiveness of the solutions developed by ABB.


ABB provided medium- and low-voltage digital solutions
for processes such as advanced phosphorus removal, along with chlorination and UV light disinfection of the discharged water guaranteeing water quality and reducing pollutants, and developed a management system aimed to prevent downtime during the upgrading phases of the facility, which serves more than 7 million Shanghainese and manages one-third of the municipal wastewater produced in the Chinese megacity.
