Intracellular mechanisms of solar water disinfection
Solar water disinfection (SODIS) is a zero-cost intervention measure to disinfect drinking water in areas of poor access to improved water sources, used by more than 6 million people in the world. The bactericidal action of solar radiation in water has been widely proven, nevertheless the causes for this remain still unclear. Scientific literature points out that generation of reactive oxygen s...
متن کاملDrinking Water Disinfection by Solar Radiation
A primary concern of developing countries throughout the world is that of obtaining safe drinking water. Waterborne diseases are still common in developing countries since drinking water sources are contaminated and the conventional rural water treatment plants are often inefficient to produce safe drinking water. This situation in developing countries is a major problem in terms of preventing ...

متن کاملDisinfection of contaminated water by using solar irradiation.
Contaminated water causes an estimated 6 to 60 billion cases of gastrointestinal illness annually. The majority of these cases occur in rural areas of developing nations where the water supply remains polluted and adequate sanitation is unavailable. A portable, low-cost, and low-maintenance solar unit to disinfect unpotable water has been designed and tested. The solar disinfection unit was tes...
متن کاملA Novel Type of Thermal Solar Water Disinfection Unit
A novel type of solar thermal water disinfection unit is presented in this work. The system is safe and easy to use and can be built with basic tools and widely available materials. In the unit, water is disinfected by temperature increase up to the boiling point and output is controlled by the change in density. For employing the change in density to control the water output, a dimensioning pr...
