Filters For Water Purification

Sand Filters

Slow sand filters pass water slowly through a bed of sand. Pathogens and turbidity are removed by natural die-off, biological action, and filtering. Typically the filter will consist of 24 inches of sand,then a gravel layer in which the drain pipe is embedded. The gravel doesn't touch the walls of the filter so that water can't run quickly down the wall of the filter and into the gravel building the walls with a rough surface also helps. A typical loading rate for the filter is 0.2 meters/hour day (the same as .2 m3/m2 of surface area). The filter can be cleaned several times before the sand has to be replaced.In Pressure sand filter, water is first filtered by Pressure Sand Filter unit for removal of suspended matters and turbidity.

There are several advantages of slow sand filtration over other methods of water disinfestation:

  • It is a low energy consuming process
  • It has great adaptability in components and applications maintenance is minimal
  • Systems can be built and installed by laymen
  • Costs of building and running significantly lower than other disinfestation method
