Water purification system by capacitive processes and the use of nanomaterials (WW CDI)
PROINGESA is leading an innovative research project to obtain a water purification system through capacitive processes and the use of nanomaterials (WW CDI).
Water is an increasingly scarce resource, and efforts to research and improve treatment systems are growing. One of the critical points in existing treatment technologies is energy consumption. Capacitive deionisation is presented as a very interesting alternative as it is a purification system with low energy consumption, competing directly with other existing technologies, such as reverse osmosis.
The basis of the process is based on supercapacitor technology. The ions to be removed are retained by electroadsorption, and the system is charged as a capacitor. Once the electrodes are saturated, the regeneration stage takes place. In this stage, the stored energy is released and can be recovered by means of an external electrical circuit.
The main objective of the project is the development of materials and components for high-performance supercapacitors based on the use of nanomaterials, to be integrated into deionisation modules. This technology is intended to reduce the amount of energy required by traditional water purification systems.
