Phototransformation of Acesulfame K in surface waters: Comparison of two techniques for the measurement of the second-order rate constants of indirect photodegradation, and modelling of photoreaction kinetics

Phototransformation of Acesulfame K in surface waters: Comparison of two techniques for the measurement of the second-order rate constants of indirect photodegradation, and modelling of photoreaction kinetics

By use of photochemical modelling we show that acesulfame K (ACE) can undergo photodegradation in surface waters, mainly by reaction with OH and possibly 3CDOM* (the triplet states of chromophoric dissolved organic matter).

Comparative effect of growth media on the monitoring of E. coli inactivation and regrowth after solar and photo-Fenton treatment

Comparative effect of growth media on the monitoring of E. coli inactivation and regrowth after solar and photo-Fenton treatment

This study intends to assess the cultivability of photo-treated Escherichia coli K-12 on media with different selectivity (PCA, LBA, T-7, T-7 + TTC, VRBA and MAC) and to establish optimal conditions for bacterial recuperation.

Legionella jordanis inactivation in water by solar driven processes: EMA-qPCR versus culture-based analyses for new mechanistic insights

Legionella jordanis inactivation in water by solar driven processes: EMA-qPCR versus culture-based analyses for new mechanistic insights

In this contribution, the validation of EMA-qPCR method for the quantification of viable Legionella spp. in water after solar treatments was carried out. EMA-qPCR was used to evaluate the different effects of several solar water disinfection processes over this bacterium, and furthermore their mode of action.

Validation of a solar-thermal water disinfection model for Escherichia coli inactivation in pilot scale solar reactors and real conditions.

Validation of a solar-thermal water disinfection model for Escherichia coli inactivation in pilot scale solar reactors and real conditions.

In the present work, the synergistic SODIS-thermal model, describing the E. coli inactivation by solar exposure (SODIS) considering the synergistic effect of solar UV photons and solar heating of water under controlled conditions of irradiance and temperature, is validated under real field conditions.

Solar disinfection of drinking water and diarrhoea in Maasai children: a controlled field trial

Solar disinfection of drinking water and diarrhoea in Maasai children: a controlled field trial

Dr. Lyndon Buck was conducting a scoping exercise to determine if local pottery/ceramic groups and plastics manufacturers might be able to produce the Solar Ceramic prototypes in Malawi. Solar radiation reduces the bacterial contentof water, and may therefore offer a method for disinfection of drinking water that requires few resources and no expertise.

Solar disinfection of drinking water protects against cholera in children under 6 years of age

Solar disinfection of drinking water protects against cholera in children under 6 years of age

Solar disinfection of drinking water protects against cholera in children under 6 years of age. R M Conroy,M E Meegan, T Joyce, K McGuigan, J Barnes. Background and Aims—We have previously reported a reduction in risk of diarrhoeal disease in children who used solar disinfected drinking water.

Randomized Intervention Study of Solar Disinfection of Drinking Water in the Prevention of Dysentery in Kenyan Children Aged under 5 Years

Randomized Intervention Study of Solar Disinfection of Drinking Water in the Prevention of Dysentery in Kenyan Children Aged under 5 Years

We report the results of a randomized controlled intervention study (September 2007 to March 2009) investigating the effect of solar disinfection (SODIS) of drinking water on the incidence of dysentery, nondysentery diarrhea, and anthropometric measurements of height and weight among children of age 6 months to 5 years living in peri-urban and rural communities in Nakuru, Kenya.

High Compliance Randomized Controlled Field Trial of Solar Disinfection of Drinking Water and Its Impact on Childhood Diarrhea in Rural Cambodia

High Compliance Randomized Controlled Field Trial of Solar Disinfection of Drinking Water and Its Impact on Childhood Diarrhea in Rural Cambodia

Recent solar disinfection (SODIS) studies in Bolivia and South Africa have reported compliance rates below 35% resulting in no overall statistically significant benefit associated with disease rates.

Solar water disinfection (SODIS): A review from benchtop to rooftop

Solar water disinfection (SODIS): A review from benchtop to rooftop

Solar water disinfection (SODIS) has been known for more than 30 years. The technique consists of placing water into transparent plastic or glass containers (normally 2 L PET beverage bottles) which are then exposed to the sun.

Field comparison of solar water disinfection (SODIS) efficacy between glass and polyethylene terephalate (PET) plastic bottles under sub-Saharan weather conditions

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.
