USA.- Scientists from the University of Illinois and Agricultural Research Organization, Israel are collaborating to reduce the use of water in aquaponics and hydroponics. To prevent plant pathogens from spreading in these soilless environments, water disinfection is required.
The researchers found that disinfection with ozone created lower toxic effects than with chlorine. They also found that lower concentration of disinfectants over a longer exposure time created lower toxicity in the recycled water. The results were presented to aquaponics and hydroponics producers in Illinois.
