The presence of anthropogenic components in surface water, sometimes already toxic at very low concentrations, challenges the applicability of conventional technologies to produce safe drinking water. The chemical charge of some components, such as boron, arsenic and some organic micropollutants, is affected by the solution pH, and effective removal is challenging with conventional technologies. An innovative, chemical-free, electrochemical technology will be developed to polish, after conventional treatment, water, and to remove these harmful components. A physical-chemical transport model will be developed, which will aid the design of this innovative process.
