BioSand Water Filters are an adaptation
of slow-sand filtration, designed for use at the household
level. The filter removes water-borne bacteria, viruses, protozoa,
and other organisms that cause diseases such as cholera, typhoid
fever, and amoebic dysentery. The filter also strains out
the particles and organic matter that cause cloudiness, unpleasant
taste, colour, and odour. |
