On June 15, 2023, the Deputy District Chief of Chancheng District, Foshan City, Guangdong Province, the Deputy Director of the District Housing, Urban-Rural Development and Water Resources Bureau, and the Deputy General Manager of Foshan Water and Environmental Protection Co., Ltd. conducted a research visit to Kunming SYS Environmental Technology Co., Ltd. SYS Group Chairman Ge Jing, General Manager Li Chongxin, and Deputy General Managers Zhao Lei and Li Lingling received the delegation. Accompanied by the leadership of SYS, they visited the Kunming City First Water Quality Purification Plant's ultra-limit phosphorus removal project, the storage regulation pond efficiency enhancement project, and the Puzi sewage treatment plant project. The water rich in dissolved oxygen discharged into the river after treatment through "rapid separation technology + spore transfer technology" has a noticeable restorative effect on the river's aquatic ecology. The Deputy District Chief highly recognized and affirmed this technology, opening a new chapter for future cooperation.

At their first stop, Li Ming and his delegation arrived at Kunming's First Water Quality Purification Plant, where the chairman of SYS personally explained the plant's core technology. A live demonstration of the water quality treatment using "rapid separation technology + spore transfer technology" garnered high praise from the leaders.

Subsequently, Deputy District Chief Li and his team visited the Puzi Wastewater Treatment Plant project, where Marketing Manager Zhang Xue introduced the construction background, design philosophy, and benefits since the plant's inception.

Finally, Deputy District Chief Li and his delegation visited Kunming SYS for an exchange on the experience of managing Dianchi Lake.
