Available data from 2013 suggest that 17% of the global population does not have access to electricity, 95% of those live in sub-Saharan Africa and developing Asia, with sub-Saharan Africa leading with 80%. This lack of electrical power accessibility reduces the number of water sanitation facilities; so the population faces a constant life-threatening risk when it comes to drinkable water because water sources are often highly polluted with germs and bacteria. The main purpose of this study is the design and implementation of a water treatment system based on the ozone disinfection mechanism and powered by solar renewable energy. The particularity of this system is its low cost versus high efficiency, and the heart of the system is a half-bridge inverter built around 16F628A microcontroller connecting the PV panel to the ozone generator. An experimental study was conducted using polluted water to test the effectiveness of the filtering system.
