SODIS : Solar Disinfection
Films Media Group (Film distributor), Network Ireland Television
Kevin McGuigan in RCSI in Dublin has been working for 20 years on a deceptively simple solution which can convert dirty water into clean water with no chemicals or additives of any kind. Aoibhinn travels to Uganda to meet Kevin and to find out about the latest Solar Disinfection (SODIS) project which is being funded by RCSI and the Higher Education Authority through Irish Aid. The project involves filling transparent PET-bottles or glass bottles with contaminated water and then exposing them to the sun for 6 hours. During this time, the UV-radiation of the sun kills disease-causing pathogens and while the process doesn't actually make the water clear, crucially, it kills the bacteria in the water and makes it safe to drink. The beauty of this solution is that it requires no technology, very little infrastructure and operates solely on the heat of the sun! Aoibhinn visits Kevin's PhD student Jacent Asiimwe to find out about the science behind the process, and the team also met with lots of schoolchildren who will directly benefit from the technology
