| Abstract | This article is a synthesis of laboratory and field research on solar water disinfection (SODIS) which has been carried out by SANDEC (Switzerland) and CINARA (Colombia), and local partners in Costa Rica, Jordan and Thailand. SODIS was applied as a batch and as a continuous flow process (SODIS Reactor). The process is most effective with a water temperature of at least 50 degrees Celsius. Transparent plastic bags allow a 3-log reduction (99.9 per cent) of faecal coliforms and Vibrio cholerae through heating and radiation at an UV-A dose of 54 Wh per square metre over a period of 140 min. The SODIS reactor produces around 100 litres of drinking water per square metre of solar collector per day. |
