Feasibility of semi-continuous solar disinfection system for developing countries at a household level
A study to assess the feasibility of a novel solar water disinfection system developed by the author, Semi-Continuous Solar Disinfection (SC-SODIS), was conducted. Three aspects of SC-SODIS feasibility were considered: technical, social and economic feasibility. This study focused on developing …

High density polyethylene (HDPE) containers as an alternative to polyethylene terephthalate (PET) bottles for solar disinfection of drinking water in northern region, Ghana
… polyethylene terephthalate (PET) bottles for the solar disinfection of drinking water in the Northern Region of Ghana, in a process know as SOLAIR. This study is in line with the intention of Pure Home Water, a registered non-profit organization in Ghana, to offer a variety of low-cost household …

Speeding up solar disinfection : effects of hydrogen peroxide, temperature, and copper plus ascorbate on the photoinactivation of E. coli in Charles River water
Sunlight efficiently disinfects drinking water in plastic bottles over two days, but simple additives may show promise for reducing this time to several hours. This study found that adding up to 500 [micro]M hydrogen peroxide accelerates the room-temperature inactivation of E. coli K12 by sunlight …

Bacteriophage PRD1 as a potential surrogate for adenovirus in drinking water disinfection with free chlorine, low pressure ultraviolet light, and sunlight
… Adenovirus is known to be highly resistant to disinfection technologies such as ultraviolet (UV) light, combined chlorine, and solar disinfection. A potential surrogate for adenovirus is the bacteriophage PRD1 because of its similar size, morphology, and genome replication mechanism. The …
