Title: Effect of Emitter Types, Operating Pressures and Treated Wastewater on the Hydraulic Performance of Drip Irrigation System Under Controlled Condition
Author: Hassan, Mohammed Elmostafa Hussain
Abstract: The experiment was carried out in the Faculty of Agriculture, University of Khartoum, during the period from May to September 2015. The objective of this study was to evaluate the hydraulic performance of drip irrigation system under controlled condition. The experimental work was held in laboratory, whereas a model for drip irrigation system used. The treatments consisted of three types of emitters (turbo, Octa and barrel) with three operating pressures (P1 (0.5), P2 (0.75) and P3 (1) bar). Treated wastewater with salinity 2.2 ds/m used as a source of water. The uniformity parameters (coefficient uniformity (CU%), emission uniformity (EU%), coefficient of variation (CV%)) and clogging percentage (Pclog) were studied. The operating pressure kept constant during the experiment for each treatment, SAS (statistical package) used to analyze the data the variations among means were checked by the least significant difference (LSD). The results showed that the Turbo pressure compensating emitter recoded significant differences (P ≤ 0.05) in increasing values of CU% and EU% compared with Octa and Barrel emitters, respectively. On the other hand, Octa and Turbo showed higher resistance to clogging phenomenon than Barrel, which recorded a high percentage of clogging. The uniformity parameters showed clear response to the operating pressures. Whereas, P3 gave the highest values of CU% and EU%, while P1 recorded the lowest values and vice versa results were recorded for CV% and clogging percentage. The conclusion of this study is that emitter types and operating pressures have profound effect on the hydraulic performance of drip irrigation system, Hence, they should be considered when dealing with drip irrigation system.
