Faecal sludge (FS) accumulates in onsite sanitation technologies, which play a prevailing role in low- and middle-income countries. However, FS management is generally lacking. FS is usually directly discharged in the environment despite its high organic l ...
Disinfection by low-pressure monochromatic ultraviolet (UVC) radiation (253.7 nm) became an important technique to sanitize drinking water and also wastewater in tertiary treatments. In order to prevent the transmission of waterborne viral diseases, the an ...
Synthetic glucocorticoids (GCs) are widely used anti-inflammatory drugs. They mimic cortisol, the natural stress hormone in humans and in fish. Cortisol binds and activates the glucocorticoid receptor (GR), which regulates genes governing development, immu ...
Iron photo-assisted inactivation of wild enteric bacteria (total coliforms/E. coil and Salmonella spp.) was carried out in water from the Sahelian wells having different pH (W1:4.9 and W2: 6.3) and a natural iron content of 0.07 mg/L We evaluate the effici ...
Since 1990, almost 1.9 billion people have gained access to an improved sanitation facility, while 2.6 billion people still live without access to improved sanitation. In urban areas of low- and middle-income countries, the majority of household rely on on ...
The inactivation of total coliforms/E. coli (10(4) CFU/mL) and Salmonella spp. (10(5) CFU/mL) in well water naturally containing dissolved (Fe2+/3+) and solid iron forms (e.g. iron oxides) was carried out by photo Fenton treatment (Fe-2+,Fe-3+/H2O2/hv). In ...
The photo-disinfection of water from two different wells (W1, pH: 4.6–5.1 ± 0.02) and (W2 pH: 5.6–5.7 ± 0.02) was carried out during the rainy season at Ouagadougou–Burkina Faso, West Africa. The weather variation during the rainy season significantly affe ...
The continuous surveillance of drinking water is extremely important to provide early warning of contamination and to ensure continuous supplies of healthy drinking water. Isolation and detection of a particular type of pathogen present at low concentratio ...
Context Worldwide: FS production much larger than treated volumes In Vietnam: • Urban households required to own septic tanks • Combined onsite and centralized sanitation • FS emptying frequency up to 10 years or more Negligible FS volumes treated before d ...
There is an urgent need to develop comprehensive and sustainable sanitation systems in developing countries, including faecal sludge (FS) treatment technologies that help reduce environmental and human health risks. Anaerobic digestion (AD) is widely used ...
