Objectives of the project: to demonstrate the technological possibility of reusing drainage in the Euro-Mediterranean regions by designing, constructing and starting up a pilot system for complete recirculation. The pilot system will be tested on tomato plants, one of the most economically important and widespread crops in southern Europe. The pilot system proposed here will be able to collect drainage from the normal irrigation of the tomato plantation, disinfect it and adjust the nutrient concentration, pH and electrical conductivity for the purpose of drainage.
