Final Report: Treatment and safe disposal of excreta in emergencies

The overall objective of this project was the proof of concept of a portable treatment system for human excreta for deployment in emergency situations based on sequencing batch reactor technology. Given its potential operation in a low resource context, this system needed to be easy to deploy and operate.

Thus, its innovative element was in the use of venturi aeration. The specific aim of this study was to test the performance of several aeration devices using venturi injectors and compare them to a “conventional” aeration system using compressed air feed in order to assess the viability of venturi aeration for the treatment system to be developed.

The final project report provides information on the methodology, activities, outputs, impact and dissemination of learning.
