  • Water treatment case study

    Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog ...

  • 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 ...
