Available Technology
Filtration system for small-medium scale wastewater and water treatment.
Technology:
Electrochemical carbon nanotube filter for adsorption, desorption, and oxidation of aqueous pollutants
Innovations and Advantages
Hybrid approach to filtration systems, providing significant advantages over conventional filtration or electro-chemical approaches to water treatment. Advantages include:
1 - Resistant to fouling or clogging, unlike a conventional filter.
2 - Electrochemistry inactivates bacteria/germs
3 - Highly energy efficient and produces hydrogen as a biproduct, resulting in lower operating costs.
4 - High throughput, making it appropriate for high-throughput or batch applications that can be converted to flow processes.
Near-term applications include industrial wastewater treatment and water treatment in hospitals and labs. May eventually be applied to higher-volume, municipal wastewater, drinking water treatment or Third World water safety.
