Geely Group
Guangxi某 Group Co., Ltd. (referred to as “某 Group”) is a super-large state-owned enterprise directly under the jurisdiction of Baise City, Guangxi Province. Over the past 60 years, the group has undergone arduous pioneering efforts and continuous reform and innovation, evolving into Guangxi’s largest coal production base—primarily producing lignite—and one of the country’s most important manganese carbonate bases. It is also a national pilot unit for green mines and a nationally recognized model coal mine for small and medium-sized enterprises. The group’s coal industry covers coal-producing regions in Guangxi as well as neighboring provinces such as Guizhou and Yunnan, and extends into the ASEAN region. For five consecutive years, the company has been listed among China’s Top 100 Coal Enterprises. Currently, the group owns 28 wholly-owned and controlling enterprises, with total assets amounting to 13.1 billion yuan and employing over 5,000 people. Its annual coal and manganese ore production capacity reaches 5 million tons. The group’s core industries include integrated coal-power-aluminum operations, integrated ecological manganese industries, manganese mining, coal logistics, coal machinery manufacturing, building materials and real estate development, and specialized engineering technical services for coal mines. This project was implemented at a power plant belonging to a subsidiary of某 Group in Baise. The reverse osmosis system membrane element replacement project was completed in July 2021. A total of 228 Haitong reverse osmosis membrane elements were used in this project, primarily designed to treat high-demand boiler feedwater. The customer expressed great satisfaction with the results achieved.
