Solar Water Disinfection
Solar Water Disinfection is a system which utilizes solar energy to remove biological agents like bacteria, protozoa, viruses and worms from water and makes it disinfection. There are three types of method to disinfect water by solar energy. They are as below:
- Method-1: Utilizing the effects of electric current produced by solar photovoltaic module.
- Method-2: Solar thermal water disinfection.
- Method-3: Disinfecting water by utilizing solar ultraviolet.
In the first method, solar photovoltaic modules are used to produce electric current which provides electrolytic processes in order to disinfect water.
In the third method, sunlight and plastic PET bottles are used to disinfect water. It is a free and effective method for decentralized water treatment. This method is known as Solar Ultraviolet (UV) Water Disinfection and familiar as SODIS. Typically, it is used in household level.
