Solar disinfection (sodis) was developed in the 1980s to inexpensively disinfect water used for oral rehydration solutions in 1991, the swiss federal institute for environmental science and technology began to investigate and implement sodis as a household water treatment option to prevent diarrhea. Solar disinfection (sodis) solar disinfection (sodis) is a water treatment technique consisting of exposing water to sunlight, specifically uva radiation unlike conventional uv water treatment, where uvc radiation directly damages the dna of pathogen, sodis utilizes uva wavelengths in order to form reactive-oxygen species (ros) in water. Cloudiness affects the strength of solar radiation and thus also the effectiveness of the method rule of thumb: if less than half of the sky is clouded over, 6 hours will be enough to completely disinfect the water.

Solar disinfection (sodis) uses solar energy in the form of ultraviolet radiation and infrared heat to disinfect contaminated drinking water poor water quality poses a major threat to human health in developing countries and water-borne illnesses are often a leading cause of childhood mortality. Disinfection of contaminated water using solar radiation (sodis) is known to inactivate bacteria its inactivation efficiency depends on local conditions where the disinfection is made this study was aiming to test the efficiency of solar disinfection using different water parameters as low-cost.
Solar disinfection (sodis) january 2008 household water treatment and safe storage (hwts) interventions are proven to improve water quality and reduce diarrheal disease incidence in developing countries. Solar water disinfection (' sodis ') is a type of portable water purification that uses solar energy to make biologically-contaminated (eg bacteria, viruses, protozoa and worms) water safe to drink. One-tenth of the world's population lacks clean water now, researchers report they have developed a cheap solar still, which uses sunlight to purify dirty water up to four times faster than a. Solar water disinfection ('sodis') is a type of portable water purification that uses solar energy to make biologically-contaminated (eg bacteria, viruses, protozoa and worms) water safe to drink water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.
Solar water disinfection (sodis for short) is a water treatment method that uses the sun's energy for disinfection the most common technique is to expose plastic bottles full of contaminated water to the sun for a minimum of one day. Solar radiation in an emergency situation, water can be disinfected with sunlight water in a clear plastic bottle, preferably lying on a reflective surface (such as aluminum foil), will be safe to drink after a minimum of 6 hours in bright sunlight. Sodis is a solar water disinfection process which works by exposing untreated water to the sun in plastic bottles field experiments were carried out in cochabamba, bolivia, to obtain standard. Solar water disinfection (sodis) has been known for more than 30 years 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.
Solar water decontamination system is a water purification system at household level based on solar radiation treatment and water distillation with additional use of solar heating it is a combination of two water purification processes, the solar water disinfection system (sodis) and the solar distillation process.
