Improved understanding and use of generated oxidizing species in liquid waste disinfection

2016 - 2017 • Duke University


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.

Stockholm World Water Week 2018!

World Water Week is organised by the Stockholm International Water Institute (SIWI) and takes place in Stockholm, Sweden. It has been the annual focal point for the globe’s water issues since 1991. Individuals from around the globe also present their findings at the scientific workshops.

Resources and publications

Our library has more than 2300 publications, factsheets, presentations, drawings etc. from many different organisations. It continues to grow thanks to the contributions from our partners.

Add item to library »

The three links below take you to special groups of items in the library for more convenient access:


The project database contains nearly 400 sanitation projects of many different organizations dealing with research, implementation, advocacy, capacity development etc. Advanced filtering functions and a global map are also available. Information on how and why this database was created is here.

People working for SuSanA partners can add their own projects through their partner profile page. You might need your SuSanA login upgraded for this purpose. Please contact us if you would like to add a project.
