1p5: Novel insights and technologies for monitoring and improving water quality in a recirculating greenhouse system

Abstract

The European Water Framework Directive and following national environmental legislation forces the greenhouse industry to close the water cycle at the company level, by increased reuse of drain water. As complete recirculation is obliged from 2027 onward, growers are challenged to manage the availability, quality and safety of the recirculated water Recurrent use of water may cause a build-up of a variety of organic compounds and this may affect plant growth, performance and food safety directly or indirectly via microbial activity.
