Description
Summary:This article aims to evaluate the uniformity of distribution in systems of application by drip tape of crude and treated wastewater from coffee fruit pulping. A platform of tests was set up, consisting of three units of drip wastewater application, each one with four lateral lines. The evaluations for uniformity of water application were done every 36h of operation. Crude wastewater caused faster emitter clogging but treated wastewater also presented high potential of dripper clogging. Dripper clogging affected the uniformity of wastewater application drastically. In the case of crude wastewater, the values for CUC and CUD were reduced to zero after 36 hours of system operation and, in the case of filtered wastewater, reductions of 76 and 100% were obtained after 144 hours of system operation.
