Recently, Beijie Te signed a strategic cooperation agreement with Jiangsu Suqing Water Treatment Engineering Group Co., Ltd., a leading enterprise in the domestic ion exchange resin industry. Beijie Te Chairman Quan Qiuhong, General Manager Zhang Jianfei, Vice Chairman and General Manager Qian Ping of Suqing Group, Sales Director and Minister of Engineering Technology Liu Jinbiao, Research Institute Director Cheng Xiaohui, and others attended the signing ceremony.

Strategic Cooperation Signing Ceremony between Beijet and Suqing Group

Beijie Te has been deeply involved in the field of wastewater resource utilization for 20 years, with internationally leading core technologies and rich project database accumulation in the zero discharge and salt separation of complex high salt wastewater in the industrial field. It has completed multiple industry benchmark projects, served more than 500 customers at home and abroad, and has more than 164 patents. It has become a leading enterprise in the industrial wastewater resource utilization.

In 2021, after entering the field of salt lake lithium extraction, Beijet proposed customized technical solutions for different salt lakes based on its significant technological advantages and rich engineering application experience. On the basis of the original experiment, the lithium recovery rate was increased by 10 percentage points, and the salt lake resources such as potassium, rubidium, cesium, and boron contained in the salt lake were comprehensively utilized, achieving maximum economic benefits and firing the first shot for the company's entry into salt lake lithium extraction. At the same time, the company has established a digital operation and maintenance center, dedicated to achieving less manpower and unmanned operation of lithium extraction from salt lakes, in response to the shortage of manpower in high-altitude areas.

This strategic cooperation is an important step taken by the company in the adsorption process after laying out the application of lithium extraction membrane technology and intelligent operation and maintenance in salt lakes. It improves the company's lithium extraction business layout in salt lakes and is in line with the company's business development and long-term strategic planning.

Suqing Group was founded in 1970 and is the largest ion exchange adsorption resin production enterprise in China with a history of 53 years. Suqing Group has a research and development team of more than 520 employees, multiple PhDs, and more than 20 senior technical talents. It has two resin production bases and produces 60000 cubic meters of ion exchange resin, adsorption resin, and 9000 cubic meters of lithium adsorbent annually. The annual processing equipment capacity is more than 20000 tons, and it has been listed as the sales champion of the ion exchange resin industry by the China Membrane Industry Association for 23 consecutive years.

In 2015, its R&D team achieved a major breakthrough in the key technology of non-homogeneous crystallization process for lithium adsorbents. In 2020, the technical team made significant improvements to the preparation process of lithium adsorbents, using new nanomaterials, composite pore forming agents, and special granulation processes. The appearance is regular (spherical, unique in the industry), the specific surface area is large, the selectivity is high, and the performance is significantly improved. It has good universality for various salt lake water quality (also applicable to oil and gas field brine), and its adsorption capacity is 50-60% higher than similar domestic products, reaching the international leading level. At the same time, the new generation of products is easy to wash (wash at room temperature), with high resolution (>95%), low dissolution rate (<1%/year), and good durability. The product performance has achieved quality. The leap forward.

This cooperation mainly focuses on the optimization and application of ion exchange resins in the field of lithium extraction from salt lakes, as well as the technological research and development of adsorption materials for cesium and rubidium extraction from salt lakes. It aims to achieve breakthroughs in cost reduction, efficiency improvement, and energy conservation in the comprehensive utilization of salt lake resources. Beijie Te and Suqing Group have joined forces, and the membrane+resin adsorption process provides strong support for lithium extraction from salt lakes!
