Page 34 - THE GLOBAL LEADER IN MEMBRANE SEPARATION INDUSTRY

PART 02 Proficient in membrane technology and
customized processes as needed

The adsorption coupled membrane process is one of the most promising technologies for
Adsorbent lithium extraction from salt lake brine, with advantages such as high efficiency, energy conservation,

environmental protection, and simple operation. However, the core material adsorbent often has
problems such as low adsorption capacity, poor selectivity, and high loss rate, which limits the
application of this technology. Through long-term technological breakthroughs, Jiuwu High-Tech
has greatly improved the performance of adsorbents. It has taken the lead in developing
titanium-based and aluminum-based lithium adsorbents, with high mass transfer efficiency and
fully independent intellectual property rights. We have also built 6000 tons per year adsorbent
production lines of the project, achieving a three-step strategy of investment, production, and sales
for the same year. In the future, our production lines will be expanded in a timely manner based on
the market demand for lithium extraction from salt lakes, further to enhance the capacity of
adsorbents.
