The development of efficient water filtration systems is an important challenge for environmental engineering. Activated carbon is widely used for adsorption of organic pollutants. However, it is only a separation process and current regeneration processes all present some important drawbacks. A new electrochemical process for in situ regeneration of activated carbon fibers has been developed. Activated carbon fibers allow for fast adsorption of organic pollutants and are subsequently used as cathode during the regeneration process. The objective is to recover the adsorption capacity of the initial material and to degrade organic pollutants.
