Henan BGT Environmental Protection Technology Co., Ltd. serves as a core R&D and manufacturing base for BGT Group. Operating from a 33,967 m² facility with a registered capital of RMB 75 million, it is the center for developing and producing BGT's proprietary water treatment technologies. The facility boasts 76 pilot assembly systems enabling rapid R&D iteration and project deployment, over 40 advanced production units, and houses one of China's largest membrane regeneration workshops. Key product offerings encompass membrane technologies such as electrodialysis membranes, high-strength membranes, and MBR membrane stacks; separation systems including reverse osmosis, ultrafiltration, and nanofiltration; and various filtration solutions like multimedia filters, activated carbon filters, and security filters. The company also provides chemical treatment units, featuring acid/alkali storage tanks, cation/anion exchangers, and mixed beds, along with specialized process equipment such as organic carbon removers, advanced catalytic oxidation towers, and continuous activated carbon adsorption columns.

Wuhai BGT Environmental Protection Co., Ltd. functions as the demonstration hub for BGT's Industrial-Municipal Synergy Model. In 2018, the company commissioned China's first integrated industrial-municipal wastewater resource recovery project, successfully implementing co-treatment and recycling of both municipal and industrial wastewater. This facility annually reuses 7.6 million tons of industrial water for park enterprises, achieving near-complete wastewater utilization and near-zero liquid discharge (NZLD). Since implementation, the project has significantly enhanced the urban water environment, improved local living and working conditions, and plays a vital role in mitigating water pollution while protecting watershed ecology. Simultaneously operating as BGT's production base for environmental materials and equipment, the 700-acre facility represents a RMB 2.9 billion total investment being developed in phases. Phase I focuses on manufacturing water purification activated carbon—a novel adsorbent material with adsorption, desulfurization, and purification capabilities—alongside environmental protection equipment. This advanced material finds wide application in toxic gas purification, waste gas treatment, industrial and municipal wastewater remediation, and solvent recovery.

Established in 2023 with RMB 50 million in registered capital, Tibet Jingrun New Material Co., Ltd. serves as a key BGT subsidiary driving expansion in salt lake lithium extraction and resource development. That same year, the company initiated construction of the Tibet Salt Lake Comprehensive R&D Base in Shigatse (Rikaze). Leveraging BGT's expertise in membrane separation technology and proven experience from industrial high-salinity wastewater ZLD salt crystallization projects, it develops customized membrane-adsorption integrated solutions tailored to specific salt lake compositions. This approach achieves lithium recovery rates exceeding 85%—surpassing industry benchmarks—alongside comprehensive extraction of potassium, rubidium, cesium, and boron, enabling true full-spectrum salt lake resource utilization.

Founded in 1994, Beijing Jingrun Environmental Protection Technology Co., Ltd. holds directorship roles at the National Engineering Laboratory for High-Concentration Refractory Organic Wastewater Treatment and serves as Executive Director & Vice President Unit of the China Membrane Industry Association (CMIA), actively participating in its Electrodialysis, Petrochemical, and Membrane System O&M Committees. The company operates specialized facilities including a professional laboratory, pilot production workshop, and equipment manufacturing plant. Through sustained R&D investment, it has developed over 20 patented technologies spanning electrochemical flocculation, softening, sterilization, electrocatalytic oxidation, and electrodialysis membrane concentration. These solutions deliver compact processes with minimal secondary pollution, achieve water recovery rates exceeding 90%, and feature low operating costs, moderate capital investment, and operational simplicity. With global project experience across petroleum refining, petrochemicals, coal chemicals, coking, power generation, steel, solar, cement, and potable water sectors, the company serves prestigious clients including PetroChina, Sinopec, China Coal Group, China Salt Group, and Sinochem Group. Core services encompass oilfield solutions such as fracturing flowback fluid and reinjection water treatment; industrial water management covering high-salinity water treatment/reuse and ZLD systems; advanced water reclamation; and operational support through industrial wastewater treatment O&M services.
