Improved understanding and use of generated oxidizing species in liquid waste disinfection To assess the feasibility of electrochemically inactivating Helminth eggs using a packed bed electrochemical reactor

Electrochemical disinfection is a very interesting approach for decentralized wastewater treatment and provides key benefits such as: in-situ generation of disinfectants, no need to supply and store chemicals, simple and relatively low maintenance processes compared to conventional cleaning procedures. Duke University proposes to advance the understanding of electrochemical processes applied to wastewater disinfection and reuse.

Mission

1. To assess the feasibility of efficiently and electrochemically disinfecting blackwater using an electrochemical packed bed reactor. 2. To investigate deactivation of Nematode Eggs in wastewater for mitigation of parasitic diseases.
