Development and testing of screen filter for micro irrigation systems [electronic resource].

Includes references.

The principal aim of this research is to study the affecting factors on the design of a screen filter for micro irrigation system, and evaluate the designed filter in irrigation system, for easy operation and maintenance of irrigation system application and introduce a higher efficiency screen filter into the local market using economical local materials, and also to control emitter clogging during washing the filter screen. In addition, the designed screen filter is compared with other screen filters available in the local market. The main results in this study can be summarized in the following: * Average discharges ranged from 12 to 33 m3/h, for imported filter, and 15 to 47 m3/h for developed filter. Pressure drop ranged from 0.1 to 0.6 bar. (10 - 60 kPa) * The average filtration efficiency was 43 % and 45 % for imported and designed filters respectively. * Economical verification of the feasibility of using the developed and imported filters is discussed.
