The industrialization linked to population growth has generated a high demand for water and food, act gradually increased waste generation. This study aimed to evaluate three models of drippers (G1, G2 and G3), operating with residual water from the cashew nut processing, aiming to determine the average values of uniformity coefficient of Christiansen (CUC). The experiment was conducted in a Experimental Water Reuse Bench (UERA) located in the Universidade Federal Rural do Semi-Arido (UFERSA), operating at a working pressure of 70 kPa and under a running time that ranged from 0 to 20 hours . At the end of the experiment it was concluded that the dripper G1 is more susceptible to clogging than drip G2 and G3, an action that can be explained by the dripper G1 has a maze with greater length, facilitating the formation of biofilm.
