Deionized water energy storage

Does Capacitive deionization save energy?

Anderson M.A., Cudero A.L., Palma J. Capacitive deionization as an electrochemical means of saving energy and delivering clean water. Comparison to present desalination practices: Will it compete?

How does water deionization work?

In this method, water is passed through the electrodes with pressure and due to the reduction of ion transfer time from saline solution to the electrodes, the rate of deionization is higher than the previous method, but the size of the pores and the effective surface of the electrodes must be increased.

What is capacitive deionization (CDI)?

Capacitive deionization (CDI) is an emerging technology for water desalination, and is based on the phenomenon of ion electrosorption. Especially for low molar concentration streams, like brackish water, CDI is a promising alternative to established technologies such as reverse osmosis.

Can Capacitive deionization compete with other water desalination methods?

The capacitive deionization method, which has been much discussed and researched in the last two decades, can compete with other water desalination methods that have a high consumption for desalination with the least energy consumption.

Which materials are used in capacitive deionization?

Although new materials have been developed to introduce electrodes in the capacitive deionization process, one of the most common and suitable is activated carbon, which is also economical to manufacture [ 41, 63, 64 ]. A new type of desalination called Membrane Capacitive Deionization was developed and introduced in the last decade [ 65, 66 ].
