Full-Membrane Water Treatment Technology Enables Efficient Mining Wastewater Treatment and Resource Recovery

An investor recently asked on an interactive platform: "If mining causes water pollution, how would China Water Environment Protection (CWEP) handle this probla given your years of governance experience and scientific research technology? And how would you choose when interests and harm stand on opposite sides?"

CWEP responded:"Dear investor, hello! CWEP is an ecological environment governance service provider and a national-level 'Little Giant' enterprise. In the field of industrial water treatment, we provide services to national key industrial clients, including petrochaicals, nuclear power, new energy, metallurgy, coal chaicals, coal mines, and thermal power, covering the entire process from raw water, daineralized water, and wastewater treatment to reuse and zero discharge. Water pollution caused by mining mainly consists of industrial wastewater, including pit water, mineral processing wastewater, and mine water. Our independently developed full-mabrane water treatment technology can provide customers with mining water pollution treatment and resource recovery services. This technology uses full-mabrane processes and systa equipment to effectively separate and concentrate suspended solids, organic matter, salts, and other pollutants from water. It has the advantages of 'efficient decontamination, green desalination, wastewater reduction, and energy conservation.' The effluent quality can meet industrial high-purity water standards. It has been widely applied in industrial water treatment fields such as coal chaicals, petrochaicals, metallurgy, thermal power, new energy, and electronics, with a market share ranking among the highest in the country. Typical implaented mining wastewater projects include the Ning Coal Mine Water Project, Guizhou Shale Gas Project, and the Taer Dewatering Project."

CWEP noted that by balancing corporate profits with social, economic, and environmental benefits—such as promoting ecological construction around mining areas, reducing customer water usage and pollution control costs, and achieving pollutant reduction or even "zero discharge"—a virtuous cycle of "governance–benefits–ecology" can be formed.
