MADFORWATER. WP3 Adaptation of technologies for efficient water management and treated wastewater reuse in agriculture. Task3.2 Engineering innovative irrigation technologies adapted to the target Mediterranean African Countries and to treated wastewater reuse. Subtask3.2.2 Calibrated nozzles for localized irrigation with treated wastewater

Abstract

The data set consists of: (i) experimental data from laboratory, using fresh water (FW) or synthetic wastewater (WW), and field observations with real treated wastewater (TWW); (ii) detailed description of the fluid mechanics simulation process, performed for an irrigation emitter designed during MADFORWATER project. This emitter is able to withstand long terms exposure to low quality effluents without any drop in its discharge. Simulation aims at evaluating various emitters design to obtain an optimal pressure-discharge curve from a localized irrigation micro-sprinkler, while the data collected from experimental field results aim at evaluating the innovative micro-sprinkler in terms of droplet production. Similar data have been collected on standard irrigation sprinklers, the objective of the research is to control the droplet size spectrum. The characteristics of existing sprinklers are not identified (droplet size is not measured) or not adapted to TWW. Potential users of this data set may include all TWW reusers that want to get rid of clogging problems or at least minimize such problems.
