    What Is Involved ?Who Use This Means and Since When ?Use of Sand Filters For Effluent TreatmentSlow Sand Filters Used to Make Water DrinkableWhere to Obtain Further Information ?The sand filter is an environmentally-friendly wastewater treatment method, which is relatively simple and inexpensive. Its principle involves percolating water through a sand bed. Schematically speaking, grains of sand form a layer which is penetrated by the water and which will stop larger particles in the intervals between grains acting like a simple sieve. Smaller particles will also be retained by the wall effect on the grain surfac在wikiwater.fr上查看更多信息

  • An Introduction To Slow Sand Filtration

    Slow sand filters use sand with effective sizes of 0.15 - 0.35 mm (see section 3) to remove a large percentage of coliforms, cryptospridum and Giardia cysts. They operate most effectively at a flow rate of 0.1 – 0.3 m/h (or m3/h/m2), which equates to 100 – 300 l/h per m2 of filter area. These filters use physical processes such as sedimentation, adsorption and straining to remove fine ...
