Ozonated water is widely employed with fish farming where it safely removes disease causing micro-organisms or fungus without using harsh chemicals that may form harmful byproducts
REMOVAL OF FINE & COLLOIDAL SOLIDS - fine and colloidal solids consist of micron sized particles that avoid most methods of separation to remain in suspension. Ozone can remove these solids by causing clumping of the solids ( microflocculation ) which allows removal by foam fractionation, filtration, and sedimentation
REMOVAL OF DISSOLVED ORGANIC COMPOUNDS - dissolved organic compounds are non-biodegradable and accumulate according to feed input, water exchange rate, and the rate of solids removal. They also give the water a characteristic tea coloured stain. Ozone removes dissolved organic compounds by oxidising them in to products that are more readily removed
REMOVAL OF NITRITE - nitrite can accumulate as production intensifies and organic loadings increase creating a toxic environment for the fish. Ozone has the ability to oxidise nitrite to nitrate
DISINFECTION - high stocking densities, associated fish stress, and increased nutrient loads found in Recirculating Aquaculture Systems ( RAS ) creates an ideal environment for fish pathogens. Ozone can effectively destroy a range of bacterial, viral, fungal, and protozoan fish pathogens.
