There are tangible savings to using ozone compared to heat or chemical use for disinfecting reuse greenhouse water. As an example, if 10,000 m3 of water is reused annually, up to USD 20-25,000 (EUR 18-23,000) can be saved on energy or fuel used to heat water up to 95 deg C. For facilities using traditional biocides, up to USD 5-10,000, excluding handling and administration costs, can be realized.
