Sand filter WikipediaSlow Sand Filtration The Safe Water System CDC

Sand filters are used as a step in the water treatment process of water purification There are three main types rapid gravity sand filters upward flow sand filters and slow sand filtersAll three methods are used extensively in the water industry throughout the world The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high Users can maintain flow rate by cleaning the filter through agitating the top level of sand or by pre treating turbid water before filtration Lab Effectiveness Field Effectiveness and Health Impact Slow sand filter lab effectiveness studies with a mature biolayer have shown protozoan 90 99 bacterial and variable viral reduction
