Detoxification And Disinfection By O₃/H₂O₂For Greenhouse Effluents Reuse Using Static Mixers

The use of an ozone - hydrogen peroxide advanced oxidation reactor system is discussed for the detoxification as well as for disinfection of greenhouse influents and effluents. Using static mixers as a reactor allows for short contact times and thus results in a very compact setup. The in situ efficiency of the treatment with an ozone dose of 10 g.m−3, a H2O2/O3 mass ratio of 0.15 g.g−1 and a contact time of about 1 s, is presented. Its application allows the use of water resources with poor chemical and microbiological qualities and/or the recycling of the effluent with a satisfactory equilibrium control for a closed loop management of the greenhouse.
