A preliminary Ames fluctuation assay assessment of the genotoxicity of drinking water that has been solar disinfected in polyethylene terephthalate (PET) bottles
Though microbially safe, concerns have been raised about the genotoxic/mutagenic quality of solar-disinfected drinking water, which might be compromised as a result of photodegradation of polyethylene terephthalate (PET) bottles used as SODIS reactors. This study assessed genotoxic risk associated with the possible release of genotoxic compounds into water from PET bottles during SODIS, using the ...

The effect of immobilized catalyst structure on the degradation of chemical and biological contaminants in simulated solar photocatalytic water purification
The performance of different configurations of titanium dioxide-coated foam supports as photocatalysts in an enhanced solar disinfection system for drinking water treatment was evaluated, using the reduction of methylene blue, 1-4-dioxane, and Escherichia coli as performance indicators. Reactors with immobilized catalysts were able to match or surpass the performance of a suspension ...

Application of solar disinfection for treatment of contaminated public water supply in a developing country: field observations
A sustainable and low-cost point-of-use household drinking water solar disinfection (SODIS) technology was successfully applied to treat microbiologically contaminated water. Field experiments were conducted to determine the efficiency of SODIS and evaluate the potential benefits and limitations of SODIS under local climatic conditions in Karachi, Pakistan. In order to enhance the efficiency of ...

A novel technology to improve drinking water quality using natural treatment methods in rural Tanzania
It is estimated that one billion people worldwide do not have access to treated drinking water. This paper reports on an investigation into the potential of indigenous or natural water treatment methods as alternatives to conventional chemical water treatment methods. The seeds of five natural plant species—Vigna unguiculata, Phaseolus mungo, Glycine max, Pisum sativam, and Arachis hypogea—were ...

Mining water from gypsum
Water resources in the world are scarce and unevenly distributed. In deserts, the only source of drinking water is groundwater, often saline and of poor quality. In many places, the groundwater levels have dropped dangerously due to overexploitation. Gypsum deposits, that are very common in deserts, are a potential source of drinking water, a fact that is realised by very few people. Gypsum ...

Disinfection of roof harvested rainwater for potable purpose using pilot-scale solar photocatalytic fixed bed tubular reactor
The potable use of harvested rainwater is limited, mainly due to contamination with various pathogenic microorganisms. Disinfection of microorganisms by solar photocatalysis is emerging as a promising technique for drinking water treatment. The present study deals with the preparation of Ag-doped TiO2 by the sol gel method, and its immobilization over the inner surface of the Pyrex glass ...

This Machine Can Make Gallons of Fresh Drinking Water Right Out of Thin Air
(CNN)Machines designed by a California-based team can produce, in some cases, up to 300 gallons of fresh drinking water a day by pulling it straight from the air. And the team just won a $1.5 million prize for it. David Hertz, one of leaders of the Skysource/Skywater Alliance, says he’s excited about what the Skywater machines could do for people living in parts of the world ...

Health gains from solar water disinfection (SODIS): evaluation of a water quality intervention in Yaoundé, Cameroon
In developing countries, the burden of diarrhoea is still enormous. One way to reduce transmission of pathogens is by water quality interventions. Solar water disinfection (SODIS) is a low-cost and simple method to improve drinking water quality on household level. This paper evaluates the implementation of SODIS in slum areas of Yaoundé, Cameroon. Promoters trained 2,911 households in the use of ...

Effectiveness of solar disinfection (SODIS) in rural coastal Bangladesh
Scarcity of drinking water in the coastal area of Bangladesh compels the inhabitants to be highly dependent on alternative water supply options like rainwater harvesting system (RWHS), pond sand filter (PSF), and rain-feed ponds. Susceptibility of these alternative water supply options to microbial contamination demands a low-cost water treatment technology. This study evaluates the ...

Algal blooms in drinking water reservoirs
Drinking water reservoirs worldwide often suffer from frequent outbreaks of algal blooms. Their water quality degrades and becomes undrinkable. Algal blooms can grow so massive that they are even visible from outer space. Rising temperatures, extreme weather, stagnant water, and excess of nutrients accelerate algae growth. On hot summers, algae can grow very fast forming dense surface ...
