Abstract

Six different types of emitters were selected for clogging susceptibility, (GR in line, Fan on line, Turbo key on line, Micro jet on line, Button on line, and Katif on line). The setup of the system consists of centrifugal pump (0.5 HP), reservoir (0.80 x0.60 x0.60m) contains water with suspended particles, tray (1m x 2m) with a height of 20 cm provided with sink pipe to collect water that comes out from emitters back to the reservoir, and piping network from the pump to the lateral lines at the upper edge of the tray. The system provided with bypass valve and pressure gauge mechanism not only to adjust the operating pressure at 1 bar but also to agitate the suspended solid in water (sand particles) during the test. Tap water source was used after adding sand particles (diameter <0.1mm) with concentration of 2 gram/liter. Emitter discharges were measured in cyclic duration (each 15 minutes). According to ASAE (1997), the coefficient of variation (Cv) of all tested emitter was good, except Em6 which was of average classification. Based on the coefficient of variation criteria the systems performance emitter discharge decrease with increasing operation time. The more sensitive emitters for clogging are Em1 and Em5 (GR in Line emitter and Button on Line emitter) respectively. While the most stand without clogging was Em6 (Katif on Line emitter). The recommended emitters are Katif on Line, and Micro jet on Line emitter. It is not recommended to use GR in Line emitter and Button on Line emitters under such conditions of suspended particles.
