| The experiments were conducted in the laboratory of Agricultural and Bio-Systems Engineering Department, Faculty of Agriculture, Menoufia University, in Shibin El kom, EGYPT. The latitude and longitude of the experimental location were 30°33‵31‶ N and 31°00‵36‶ E respectively. A lateral line of Poly Ethylene (PE) with 45 m long and 16 mm diameter was used for testing the hydraulic performance of three emitter type which were (long path, short path and pressure compensating emitters). Every lateral line contained 90 emitters of the same type with nominal flow rate (4 l/h) and 100 kPa operating pressure, according to the spacing between laterals which was 0.75m, and the spacing between emitters which was 0.5 m. two filtration process were tested which were (sand filter and sand filter with screen one). The management drip irrigation system was focused mainly to reduce emitters clogging and evaluate the hydraulic performance of the drip irrigation system based on water quality, emitter types, lateral line length, and filtration process. By the aid of operating time until the completely clogging percent. The effect of all these Para tore were derived. Long path emitter recorded the highest values of the studied parameters, where the maximum emitter clogging percent were (47.44% at 880h, 47.3% at 780h and 48.6% at 680h) for the three levels of water quality. the increasing emitter clogging percent were (5.1, 6.1 and 7.1%) for the Nile water, treated drainage water and drainage water respectively. The other two tested emitter gave (8.5, 9.4 and 11.1%) and (7.2, 7.4 and 8.2%) for short path emitter and pressure compensating emitter respectively. These values were achieved at the first filtration process and it’s increased at the operating time in the rate of (102, 77 and 74%) for long path emitter, (74, %) for short path emitter and (42%). | ||||
