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 with additional use of solar heating. Contaminated 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. However, the distilled water is not drinkable since the water may still contain bacteria, viruses and in some cases protozoans. To address this problem, the distilled water is then 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 bacteria in the contaminated water. Solar water disinfection is an effective way to purify drinking water as it is recommended by World Health Organization[2]. It uses only solar energy and can be built using only recycling materials, thus, the system has no additional environmental impacts.
