![]() ![]() This review attempts to revise all relevant knowledge about solar disinfection from microbiological issues, laboratory research, solar testing, up to and including real application studies, limitations, factors influencing adoption of the technique and health impact.Įnergy Technology Data Exchange (ETDEWEB) More than 5 million people disinfect their drinking water with the solar disinfection ( SODIS) technique. Since SODIS is simple to use and inexpensive, the method has spread throughout the developing world and is in daily use in more than 50 countries in Asia, Latin America, and Africa. Since 1980 much research has been carried out to investigate the mechanisms of solar radiation induced cell death in water and possible enhancement technologies to make it faster and safer. It has been repeatedly shown to be effective for eliminating microbial pathogens and reduce diarrhoeal morbidity including cholera. Its germicidal effect is based on the combined effect of thermal heating of solar light and UV radiation. Exposure times vary from 6 to 48 h depending on the intensity of sunlight and sensitivity of the pathogens. The technique consists of placing water into transparent plastic or glass containers (normally 2 L PET beverage bottles) which are then exposed to the sun. Abstract: Solar water disinfection ( SODIS) has been known for more than 30 years. â–º Description of the economic and behaviour change aspects of this technology. â–º An examination of both laboratory and field studies. Highlights: â–º A thorough review of current state of play of solar water disinfection. Students fill their bottles at home and expose them to the sun while they are at school.
