University of Bath uses SODIS for rural areas

A multi-disciplinary research project at the University of Bath hopes to develop an efficient, portable and low cost continuous treatment system for contaminated drinking water for poor rural communities in developing countries.

The researchers are using 3D printing to generate rapid prototypes and test them using a unique indoor solar light, which will enable a better understanding of the optimal design of this household water treatment (HWT) system to most efficiently produce safe drinking water.

Currently, one of the simplest ways to treat microbial contained water is by using what is known as a “SODIS Bottle” (SOlar DISinfection), a simple plastic bottle which deactivates microbes through a combination of heat and UV light from the sun.

This project will concentrate on Africa as a key beneficiary of the technology. In particular, Malawi will be used as a case study to test the prototype devices in the field and understand how this technology can be best understood and adopted by the local communities.
