Ozone has been used to purify water since the early 1900's, initially to treat municipal wastewater. Eventually, it was introduced as a water treatment system used in aquariums, swimming pools drinking water, industrial process water and fish farms producing fish for human consumption.
Ozone is a powerful oxidizing agent that effectively targets organic matter, viruses, bacteria and parasites. It also targets off-flavour compounds, such as geosmin, and may introduce a new way to avoid the expensive and time-consuming purging of fish grown in recirculating aquaculture systems (RAD). Ozone rapidly decomposes and turns to pure oxygen, giving rise to additional benefits in both the water environment and biofilter.
Research evidence has shown ozone provides promising advantages for water treatment in RAS facilities
