Ozone: an efficient water treatment for Aquaculture
Have you considered how ozone can improve aquaculture water quality?
Applying ozone to aquaculture water treatment is a fantastic option to keep a healthy environment in the aquarium leaving no residual. With an ozone generator, it is possible to have an aquaculture water quality monitoring system, while treating the water.
So, how can ozone be so efficient in your aquarium’s water treatment? Read more below!
In re-circulation aquaculture systems (RAS), particles such as fish feces, unconsumed feed, bacteria and algae can cause several problems, as they end up harboring pathogens that will physically irritate the fish and, after decomposition, release ammonia and consume oxygen from the water.
The use of ozone in the re-circulating water system in aquaculture allows the user to benefit from a greater flexibility in site selection, reduced water usage, substantially improved water quality and reduced level of waterborne diseases.
Concentration and time
The effectiveness of disinfection increases with the concentration and duration of exposure to an antibacterial. Therefore, increasing the duration and / or concentration of ozone reduces the burden of the pathogen, but has negative effects on animals, so the concentration and duration of exposure to ozone has to be studied case by case, varying from species to species.
Directly proportional to the rate of a chemical reaction and will accelerate oxidation and thus the effects of ozone over a given time period and concentration.
Water quality and salinity.
The highly reactive nature of ozone means that it decomposes to free radicals and other ozone derived chemical species, leaving ‘residual’ dissolved ozone.
Additional contaminants that react with ozone, such as particulates, total organic carbon load, bicarbonates and carbonates, contribute to the ‘ozone demand’ of a system, effectively competing for ozone and reducing the amount available for pathogen inactivation, which will improve animal physiology and growth.
Species and life stage
Within taxonomic groups, different species can show contrasting tolerances to ozone. Optimal ozone treatment may also vary inside particular life stages.
Species with a larger egg diameter experience a better hatching rate, after ozone exposure. However, any correlation between size and tolerance may simply be a coincidence or related to species.
Environmental differences impact on phenotype (tolerance to ozone or oxidants) within species, however, genetic (family or brood) differences may also be an inﬂuencing factor.
