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.

Competitive advantages:

  • Higher performance of activated carbon fibers (high adsorption capacity, fast adsorption kinetics) compared to granular activated carbon
  • In-situ regeneration of activated carbon fibers, in the same reactor where filtration is performed;
  • None chemical reagents and process performed at atmospheric pressure and ambient temperature;
  • None attrition / oxidation of the activated carbon fibers thanks to cathodic polarization protection;
  • Complete degradation and mineralization of organic pollutants; avoid biological activity development inside the filter;
  • Compact, robust, high automation and easy operation process (current intensity is the main operating condition).

Applications:

  • Drinking water
  • Food industry
  • Water purification
  • Wastewater
  • Blood filtration
