At present, agriculture is the human activity which requires more volume of water. Given the importance and scarcity of this resource, the efficient use of water has become a priority. On one hand, if possible, it is necessary to use irrigation systems such as microirrigation that use water more efficiently. On the other hand, treated wastewater reuse by agriculture helps to have the necessary water at the same time that it allows to release water of higher quality for other uses. In this sense, microirrigation is the safest system to apply reclaimed effluents. However, its main problem is emitter clogging, which can negatively affect crop yields and system maintenance. In order to avoid emitter clogging, the use of filters is compulsory. Those filters that work better with effluents are sand filters, although, due to their pressure requirements, concentrate most of the energy demand of drip irrigation systems. This thesis determines the effect of three types of sand filters with different drainage designs (arm collector, inserted domes and porous media), two media height (0.2 and 0.3 m) and two filtration velocities (30 and 60 m/h) in the quality of filtered water, the pressure loss in the filters, the energy consumption of the system and emitter clogging
