Applying ozone for the cleaning of our eco-ponds is an innovative way to replace the use of harmful chlorine. Used for disinfection, ozone is able to maintain a certain level of cleanness of the ponds and after the purification process ozone decomposes to oxygen without damaging the ecosystem of the ponds. ITRI-Ozone Float is able to move spontaneously without manual operation due to solar power generator and ozone propulsion. Hence, it can be characterized as a water-saving, environmentally friendly as well as easy-to-use solution.
