Capacitive Deionization



The principle of capacitive deionization is very similar to that of supercapacitors. It also uses porous activated carbon as the electrode material, and physically absorbs the ions in the liquid.

Submersible for adsorption to achieve desalination effect. At present, it is mostly used in the recovery of cooling water in various industrial fields, and compared with the traditional reverse osmosis technology, the use of capacitors to Ionization is an emerging technology because of its low energy consumption and high recovery of available water resources.


In recent years, the supply of water resources is obviously insufficient, which is attributed to the drought or uneven rainfall caused by climate change. According to the assessment of the United Nations, by 2025, two-thirds of the world's population may face water shortage problems. Water efficiency is an issue that all countries must face. Energy uses activated carbon in the electrode material of capacitive deionization to increase ion adsorption to improve performance. In the future, it can be applied to seawater desalination, hard water softening, or recovery of precious metals, so that water can be recycled continuously. At the same time recover high-priced substances, which echoes the sixth item in the sustainable index: clean water and sanitation, providing a clean water resource solution for the world.
