Abstract: The present study is to evaluate the proper cylindrical screen filters manufactured locally in Egypt. The cylindrical screen filter materials are available locally. The evaluations included different sources of water (surface and ground water).
The operating characteristics of cylindrical screen filters predicated by knowledge of their mesh per linear inch, some hydraulic properties and effect of water quality on the operation duration.
The study reveals that some cylindrical screen filters can be used after sand filters when the source of water is surface water and located directly after pump station when the source of water is ground water.
Screen filters are best selected for water source with low solid's concentration as insurance for (clean water) or as secondary filter downstream of a pre-filter. Filtration efficiency tests can be easily and effectively done under laboratory and field condition (surface and ground) in all filters in two different qualities water. This is especially valuable because it can help identify faults in any micro irrigation system. The construction, measuring theory, operation, tests results and applications of two different sites will be described here.
