Screen filters are simple and economical filtration devices of various shapes and sizes that are frequently used for the removal of physical contaminants. They can be made of metal, plastic, or synthetic cloth enclosed in a special housing. Screen filters are recommended for the removal of very fine sand or larger sized inorganic debris from irrigation water. It is normally not effective to use screen filters for the removal of heavy loads of algae or other organic material typical in surface water supply, since screens clog rapidly, requiring too frequent cleaning to be practical. Selection of a filter depends on the type and amount of contaminants in the irrigation water, the type of emitters, the size of the irrigation system, and the desired management practices. Screen filters should be a primary choice when water is pumped from a well where the only filtration requirement is to remove mineral particulate matter. They are sufficient in the absence of organic contamination and in addition they are usually inexpensive and easy to maintain.
