ECE department 6th semester student Aditya Singh Rajput(1629821) found a Clean water problem and made project Solar Energy based water Purifier in the session 2018-2019. This project select in Finale of Hackathon 2018 on June 18-22, 2018 at IIT Roorkee.
To solve clean water problem, the contaminated water would be contained in clean, transparent Polyethylene terephthalate (PET) bottles and are exposed to the sunlight for a certain amount time (depending on the intensity of the sunlight) allowing the solar radiation to deactivate any waterborne pathogens in the contaminated water. Solar water disinfection is an effective way to disinfect drinking water as it is recommended by World Health Organization. The solar water purification system uses only solar energy and can be built using recycling materials, thus, the system is environmentally sustainable.
