Batch solar disinfection (SODIS) inactivation kinetics are reported for suspensions in water of Campylobacter jejuni, Yersinia enterocolitica, enteropathogenic Escherichia coli, Staphylococcus epidermidis, and endospores of Bacillus subtilis, exposed to strong natural sunlight in Spain and Bolivia. The exposure time required for complete inactivation (at least 4-log-unit reduction and below the...

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 Medicin...

• Enhanced bacteria inactivation at low water temperature by UVA- and solar-based AOPs. Mechanism of suggested. Preliminary cost estimation AOPs was performed. Carbon footprint in Spain Finland compared. In this work the effect (6 ± 1 °C 22 °C) on (10 4 –10 6 CFU mL ?1 ; Pseudomonas spp. , Aeromonas spp . Enterobacter spp.) simulated aquaculture streams (SAS) using UVA based advanced oxidation ...

In this study, the photocatalytic ozonation process using either UV lamps with a wavelength close to a solar wavelength (UVsolar) or natural solar light was established to study the effects of the major operating parameters on the removal of a toxic disinfection by-product (DBP), dichloroacetonitrile (DCAN), from drinking water. Based on the test results of a bench system, the UVsolar/TiO2/O3 p...

Poor access to drinking water, sanitation, and hygiene has always been a major concern main challenge facing humanity even in the current century. A third of global population lacks microbiologically safe especially rural poor areas that lack proper treatment facilities. Solar water disinfection (SODIS) is widely proven by World Health Organization as an accepted method for inactivating waterbo...
