High efficiency and low consumption membrane desalination technology and key materials

We have basic conditions such as factory buildings, research and development platforms, and pilot platforms, with sufficient personnel and funds. In addition to the energy layout and pollution control of reverse osmosis seawater desalination systems, the comprehensive performance of key membrane materials in the reduction and utilization process of concentrated seawater membrane method needs to be improved. Through intelligent exchange and collaborative development, we aim to systematically optimize the energy distribution, process mass transfer, and pollution control of system level equipment. At the same time, we aim to develop new high-performance membrane materials with excellent flux, pollution resistance, and wettability for concentrated seawater concentration.

Freshwater resources are fundamental natural resources and strategic economic resources, which are related to national security and regional sustainable development. Taking Xiong'an New Area and Bohai New Area as examples, the current freshwater supply and demand gap amounts to 230 million cubic meters per year, and the water resource carrying capacity has reached the natural upper limit, resulting in a very prominent supply-demand contradiction. The shortage of freshwater resources has become one of the key bottlenecks restricting the high-quality development of regional economy and society. Seawater desalination can effectively alleviate the shortage of freshwater resources and is a strategic emerging industry in the country. Reverse osmosis is the mainstream technology for seawater desalination, and currently accounts for 65% of the global seawater desalination market production capacity. However, the total production capacity of reverse osmosis seawater desalination in China is still relatively low, only 1.2% of the global reverse osmosis seawater desalination capacity during the same period, and there are key common problems such as high water production energy consumption and large discharge of concentrated seawater. In addition, China's independent core technology in this field is not strong in leadership, lacks forward-looking and disruptive technologies, and the performance stability and maturity of key materials are insufficient. The above issues have constrained the further development of China's membrane desalination industry.
