Water disinfection by solar radiation in a green house effect device
The water-borne diseases are major concerns in developing countries since they are the main cause of sickness and death among the population in rural communities. The traditional methods such as chlorination and the use of fuelwood to boil water has important environmental consequences and in some cases are rejected by population. The solar water heaters are considered as an effective, low cost ...

Does sunlight change the material and content of polyethylene terephthalate (PET) bottles?
ABSTRACTA simple water treatment process called SODIS (solar water disinfection) consists of filling polluted water in PET bottles that are exposed to sunlight for 5–6 hours. However, sunlight does not only destroy disease-causing microorganisms found in the water but also transforms the plastic material into photoproducts. Laboratory and field tests revealed that these photoproducts are ...

Visible and solar light photocatalytic disinfection of bacteria by N-doped TiO2
A water treatment system was developed based on a photocatalytic process, employing immobilized N-doped TiO2, which worked under solar radiation. Batch reactor studies were conducted using an immobilized and suspended form of N-doped TiO2. Activities of Degussa P-25 and N-doped TiO2 were compared. Optimization of catalyst concentration was also carried out. Reaction rates under different ...

Solar Water Pump Solution for Gram Seva Kendra Village - Khadsali - Case Study
Introduction Solar water pumps can supply water to locations which are beyond the reach of power lines. Commonly, such places rely on human or animal power or on diesel engines for their water supply or where the frequent power cuts are observed and the power when available is not pure and enough (Indian Conditions in Rural). Solar water pumps can replace the current pump systems and result in ...

Influence of solar water disinfection on immunity against cholera – a review
Cholera remains a problem in developing countries. This is attributed to the unavailability of proper water treatment, sanitary infrastructure and poor hygiene. As a consequence, countries facing cholera outbreaks rely on interventions such as the use of oral rehydration therapy and antibiotics to save lives. In addition to vaccination, the provision of chlorine tablets and hygiene ...

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 ...

Field comparison of solar water disinfection (SODIS) efficacy between glass and polyethylene terephalate (PET) plastic bottles under sub-Saharan weather conditions
Concerns about photodegradation products leaching from plastic bottle material into water during solar water disinfection (SODIS) are a major psychological barrier to increased uptake of SODIS. In this study, a comparison of SODIS efficacy using glass and plastic polyethylene terephalate (PET) bottles was carried out under strong real sunlight and overcast weather conditions at Makerere ...

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 photocatalytic enhancement of acrylic and PET solar water disinfection (SODIS) bottles
The solar water disinfection method (SODIS) was modified by the addition of a photocatalytic layer of titania on the interior surface of polyethylene terephthalate (PET) and acrylic bottles. Titania was solvent deposited on the interior of commercially available PET bottles, as well as bottles that were constructed from acrylic. Uncoated and titania-coated acrylic bottles removed ...

The effect of pyrite on
Escherichia coli in water: proof-of-concept for the elimination of waterborne bacteria by reactive mineralsWe present proof-of-concept results for the elimination of waterborne bacteria by reactive minerals. We exposed Escherichia coli MG1655 suspended in water to the reactive mineral pyrite (FeS2) at room temperature and ambient light. This slurry eliminates 99.9% of bacteria in fewer than 4 hours. We also exposed Escherichia coli to pyrite leachate (supernatant liquid from slurry after 24 ...

Impact of a natural coagulant pretreatment for colour removal on solar water disinfection (SODIS)
Solar water disinfection (SODIS) is the process of treating microbiologically contaminated water in clear plastic bottles through exposure to sunlight. One of the major limiting factors of this treatment is source water quality. This work investigates the impact of source water colour on SODIS efficiency and evaluates a natural coagulant for colour removal. The ability of Moringa oleifera seed ...
