Efficiency in the disinfection of water for human consumption in rural communities using solar radiation

Nevertheless, the use of solar concentrators and bottles partially painted black increases the TC and EC inactivation efficiency, reducing the solar exposure time required for a total disinfection to just 2 h. With the use of solar concentrators and partially blackened bottles, the water temperature reached 65 °C, while only 50 °C were achieved when using the same concentrators and completely transparent bottles.
