During the process of filtration, raw water can percolate through the porous sand medium, stopping and trapping organic material, bacteria, viruses and cysts such as Giardia and Cryptosporidium. The regeneration procedure for slow sand filters is called scraping and is used to mechanically remove the dried out particles on the filter.
Slow sand filters are recognized by the World Health Organization, [15] Oxfam, [16] and the United States Environmental Protection Agency [17] as being a superior technology for the treatment of surface water sources in small water systems. According to the World Health Organization, "Under suitable circumstances, slow sand filtration may be ...
