This invention is a filtration technology for water purification, based on an electrochemically active carbon nanotube filter, intended initially for wastewater treatment and water purification.

This approach combines the advantages of filtration and electrochemical oxidation into a single device, providing significant advantages over conventional approaches. Near-term applications include industrial wastewater treatment and water treatment in hospitals and labs, but the technology could be applied to higher-volume, municipal wastewater, drinking water treatment, or water safety in developing nations.
