Design of a Filtration System for a Small Scale Water ...

Polytechnic, Nigeria 2 ... Filter sand has a grain size of 0.4-1.0mm which is large in comparison with many of the smaller particles carried by water and the rapid gravity sand filter can only operate as intended when coagulants have been used. Interception of the suspended matter by the sand is a fairly complex process, but most of the suspended matter is removed by adhesion to the surface of ...

Slow Sand Filtration in Developing Countries CDEnviro

However, as the sand continues to filter sediment, over time the flow rate of the water often slows down so much that it becomes inefficient. The long-term impact of this is that it limits the capacity of the SSF to reach its full beneficial potential during its lifecycle. Thereby, hindering the sustainable effectiveness of SSF as a reliable water purification system.

Factors Affecting Filtration Rates

tive size of the filter sand is halved, the filter runs will be shortened to one-quarter of their former length. Those troubled with short filter runs who want to increase the sand size might increase the effective size 40 per cent, thus doubling the filter runs. Such a change may simultaneously produce an unsatisfactory filtered-water quality. Another important factor governing the size of ...

Sand Filter - an overview ScienceDirect Topics

Sand filters use either graded sand (fine to coarse or heterogeneous) or coarse monograde sand (uniform size or homogeneous). No single media specification (size and depth) can be applied universally for all waters; the choice depends on the water quality and upstream processes, filtered water quality objectives, cleaning method, filtration rate and length of filter runs.
