In case of low turbidity water filtration with low rate can eliminate turbidity without chemicals assist in sedimentation so that total flok (Floc) and does not require the use of settling tank for removal of turbidity and the aforementioned flok. Water production system is a mechanical or electrical device that has a minimal or none at all. It is possible to filter the water, without electricity, so it is suitable to use in rural areas has slowly filtered tank approx. 0.13-0.42 m 3/m. 2-hours. In the current the slow sand filter tank filter is used because it is very limited. Tank top with more speed. However, in a village far away from civilization, and there are no facilities for various land prices low makes the tank slowly. Somma is a different than with the slow control of the tank can be done easily without the people who have special knowledge and without electricity.
Advantages
• As they require little or no mechanical power, chemicals or replaceable parts, and they require minimal operator training and only periodic maintenance, they are often an appropriate technology for poor and isolated areas.
• Slow sand filters, due to their simple design, may be created DIY. DIY-slow sand filters have been used in Afghanistan and other countries to aid the poor.
• Slow sand filters are recognized by the World Health Organization , Oxfam, United Nations and the United States Environmental Protection Agency as being superior technology for the treatment of surface water sources. According to the World Health Organization, "Under suitable circumstances, slow sand filtration may be not only the cheapest and simplest but also the most efficient method of water treatment."
