| Abstract | ||||
| In this study a lateral line of Poly Ethylene (PE) with 45m long was used for testing three emitter types which were: long path, short path and pressure compensating emitters. The inner diameter of lateral was 16mm. Every lateral line contained 90 emitters of the same type with nominal flow rate (4 L/h) at 100 kPa of operating pressure. The spacing between laterals was 0.75m, and was 0.5m between emitters. The emitters were tested with three levels of irrigation water quality: Nile water, treated drainage water and drainage water under two filtration processes (sand filter only and sand plus a screen filters). The conducted experiments were carried out in the laboratory of Agricultural and Bio-Systems Engineering Department, Faculty of Agriculture, Menoufia University, in Shbin El kom, Egypt. The latitude and longitude of the experimental location were 30°33‵31‶ N and 31°00‵36‶ E, respectively. By the aid of operating time until the completely clogging occurred. The effect of all these Parameters 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 degree 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. | ||||
