Capacitive deionization (CDI) is an emerging technology for the facile removal of charged ionic species
from aqueous solutions, and is currently being widely explored for water desalination applications. The
technology is based on ion electrosorption at the surface of a pair of electrically charged electrodes,
commonly composed of highly porous carbon materials.

NANOPOL project aims at the development of novel electrochemical processes for water desalination
and wastewater treatment applications using nanocomposite electrodes consisted of nanocarbon
materials and conductive polymers (membrane-assisted capacitive deionization, mCDI).

In this way the system’s performance can be improved (up to 50%) as compared to the common CDI.

DELTA-MPIS developed a computational tool which conducts an economic viability study comparing
capacitive deionization with other technologies and estimates the energy required and the cost of
drinking water production per cubic meter.

DELTA-MPIS designed the electrochemical cell and contributed towards optimization of the elementary
electrochemical cell and up-scaling the whole process by computational means, predicting fluid velocity,
pressure losses, specific salt adsorption capacity.
