Ozone Water Treatment for Aquaculture
Ozone has seen wide use in aquaculture because it has a rapid reaction rate, produces few harmful reaction by-products in freshwater and oxygen is produced as a reaction end-product. Ozone is an extremely reactive oxidant and a very effective bactericide and viricide. Ozone can also be used to achieve water quality improvements by micro flocculating fine particulate matter (making particles that are easier to settle or filter) and oxidizing non-biodegradable organic molecules (creating smaller and more biodegradable molecules), nitrite, and refractory organic molecules (reducing watercolor). If nitrate levels in the water are high, nitrites will also accumulate in the blood and tissues of fish, where it interferes with oxygen transport.

Despite these apparent positive effects, ozone use in recirculation systems has been linked to reducing the level of bioavailable iodine in saltwater systems, resulting in iodine deficiency symptoms such as goiter and decreased growth in Senegalese sole (Solea senegalensis) larvae.

Unlike such agents as chlorine or any of its derivatives, oxidation with ozone leaves no hard to handle or toxic residues requiring subsequent complex treatment. In practice, ozone immediately starts to attack the oxidizable components it comes into contact with. This property makes it a very powerful disinfectant. Because the process only leaves “oxygenated” products and oxygen, it is particularly well suited for applications such as hatchery water where the presence of undesirable elements after treatment could have grave consequences.
