Abstract
The capture and re-use of greenhouse irrigation/fertigation water is an efficient use of ever more limited water resources. Although, when capturing and re-applying fertigation solutions there is a greater risk for both pathogen proliferation and chemical contaminant accumulation, both of which can lead to reduced productivity and, in more severe cases, crop loss. In order to avoid these obstacles, it is important that grower’s employ some form of water treatment. Electrochemical disinfection can be used to treat irrigation water by producing and recycling chemical components, in situ, that limit pathogen proliferation while degrading chemical contaminants. Two electrode types (Dimensionally Stable Anodes & Boron-Doped Diamond) using regenerative in situ processes are tested and will be evaluated on their suitability for crop production. Upon analyzing the electrochemical systems’ ability for disinfection and organic pollutant degradation, they appear to be compatible with crop production following preliminary trials.
