Solar Water Disinfection in Household Settings: Hype or Hope?
نویسنده
چکیده
Millennium Development Goal (MDG) 7, and its target 3, aims to halve the proportions of people globally without sustainable access to safe drinking water and basic sanitation by 2015 [1]. Others have argued that access to safe drinking water is a fundamental human right [2]. Several interventions to improve access to clean water and sanitation, including one reported in this week’s PLoS Medicine [3], have been evaluated and found to have varying degrees of success. As such, the key question remains unanswered: do water and sanitation interventions offer hype or hope?

Drinking water quality and solar disinfection: effectiveness in peri-urban households in Nepal.
The study examined pH, turbidity and fecal contamination of drinking water from household water storage containers, wells and taps, and the Godawari River, and tested the effectiveness of solar disinfection (SODIS) in reducing levels of fecal contamination from household containers. The research was conducted in 40 households in a village 6 km outside the capital city of Kathmandu, Nepal. Three...

In low income settlements where the quality of drinking water is highly contaminated due to poor hygienic practices at community and household levels, there is need for appropriate, simple, affordable and environmentally sustainable household water treatment technology. Solar water disinfection (SODIS) that utilizes both the thermal and ultra-violet effect of solar radiation to disinfect water ...
متن کاملSolar disinfection: an approach for low-cost household water treatment technology in Southwestern Ethiopia
Disinfection of contaminated water using solar radiation (SODIS) is known to inactivate bacteria. Its inactivation efficiency depends on local conditions where the disinfection is made. This study was aiming to test the efficiency of solar disinfection using different water parameters as low-cost household water treatment technology. Inactivation of microbes was tested using fecal coliform as t...
