Several types of filters are used for water treatment. Early slow sand filters typically have filter rates of gpm/ft2 of surface area and require large filter areas. The top several inches of the sand has to be removed regularlyusually by handdue to the mass of growing material 'schmutzdecke' that collects in the filter. Sand removed is usually washed and returned to the filter .

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 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 .
The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological filtration and .

Sand filters are used to remove suspended solids from water. H2K industrial sand filters are designed to remove larger suspended solids (50100 microns), using a single size of filtration media. The coarseness of the filtration process can be determined by adjusting the size of the filter sand. The effective size of each granule of sand typically varies from – Industrial sand ...
In slow sand filters, used mainly in municipal water treatment, the sand bed may be to 2 m deep. Due to the slow flow rate, a thin slimy layer of biomass forms on top of the sand. This layer contributes to the purification of the water, acting as a biofilter (see ), but when it becomes too thick it is mechanically removed to restore flow rate. View chapter Purchase book.

Slow sand filtration is a type of centralised or semicentralised water purification system. A welldesigned and properly maintained slow sand filter (SSF) effectively removes turbidity and pathogenic organisms through various biological, physical and chemical processes in a single treatment step.
A biosand filter (BSF) is an adaptation of the traditional slow sand filter, which has been used for community drinking water treatment for 200 years. The biosand filter is smaller (about 1 m tall, m wide on each side) and adapted so that it does not flow continuously, making it suitable for use in people's homes. The filter container can be made of concrete or plastic. It is filled with ...
In water treatment, the conventional sand medium has an effective size of mm, a uniformity coefficient less than, and a bed depth of 2430 in. For dualmedia filters, the top anthracite layer has an effective size of mm, a uniformity coefficient of less than, thickness of a few inches to two thirds of the total filter thickness of 2430 in., and is underlain .
