    en.wikipedia.org/wiki/Ultraviolet_germicidal...

    Dosages for a 90% kill rate of most bacteria and viruses range between 2,000 and 8,000 μJ/cm 2. Larger parasites such as Cryptosporidium require a lower dose for inactivation. As a result, US EPA has accepted UV disinfection as a method for drinking water plants to obtain Cryptosporidium , Giardia or virus inactivation credits.

  4. Sulfur-reducing bacteria - Wikipedia

    en.wikipedia.org/wiki/Sulfur-reducing_bacteria

    Sulfur reducing bacteria are used to remove Arsenite from the arsenic-contaminated waters, like acid mine drainage (AMD), metallurgy industry effluents, soils, surface and ground waters. The sulfidogenic process driven by sulfur reducing bacteria (Desulfurella) take place under acid condition and produce sulfide with which arsenite precipitates ...
