Abstract

Research indicates that the use of Emitters in more suitable for use with wastewater than other irrigation methods. In order to study the Emitter’s discharge variation by using refined wastewater in drip irrigation systems, two drip irrigation systems (a water well system as control treatment and the other with a Miandoab refinery refined wastewater as main treatment) was installed and implemented. Due to the difference and sensitivity of various emitters against physical clogs affected by water-soluble, four emitters consists of 4-liter Euro-droplet emitter with 1-meter outlet distances, two 4-liter Iran drip emitter with 1-meter outlet distances and the 16mm type tube was used at 20 to 30 cm output distances. The systems were tested in a 4-meter pressure mode and it was determined that the Euro-drip emitter has the best performance and with technical and appropriate management, the system has the ability to run with the refined wastewater. The results showed that the Euro-drip emitter indicates the lowest percentage of discharge decreases. The highest emitter absolute dispersion uniformity percentage during operation with a 4-meter pressure is related to the Euro-drip with 95.6% and the lowest value for the Iran-drip with 88.15%. Also, Iran-drip emitter the most discharge decrease by 29.4%.
