Solar Water Disinfection System with Solar heating
Similar to Solar Water Disinfection System [1] (SODIS) Solar Water Disinfection System with solar heating is a water purification system for household based on solar irradiation and solar heating. If necessary, contaminated water(turbid water) is first distilled by using a solar heated low-temperature distillation system to remove any non-volatile solid impurities such as salts, sediment and heavy metals. Then the distilled contaminated water is contained in clean and transparent PET bottles or glass bottles and are exposed to the sun light for a certain amount time (depending on the intensity of the sun light) allowing the irradiations to deactivate any pathogenic enteric bacteria. Solar water disinfection is an effective way to purify drinking water as it is recommended by World Health Organization. It uses only solar energy and can be built using only recycling materials, thus, the system has no additional environmental impacts.
