ResumoThe drip irrigation systems are the most suitable for irrigation with wastewater due to high application efficiency and low risk of contamination of agricultural produce. This study aimed to assess clogging in different emitters, using treated sewage effluent (TSE) with two types of filters (screen and hard). An operating unit of drip irrigation, with 12 lateral lines (LL) and operated at 100 kPa, was installed with three different models of drippers , called (D1, D2 and D3) . As irrigation water used in the TSE pure conditions and diluted to 50%. Evaluations were performed at baseline and every 80 hours of operation of the system, totaling 5 reviews (0, 80, 160, 240 and 320h). Coefficient of variation of discharge (CVD) on flow rate (Fr) and degree of clogging (DC): To evaluate the performance of the emitters , the following parameters were used . The results support the conclusion that no significant effect of time of use of the dripper was detected in reducing the flow of the drippers, the CV rose only for the D3 model showing greater magnitude of this coefficient used when the TSE was diluted and there was no difference when using the DC screen and disk filter to EET diluted or pure.
