Application overview
Protect the water that supports the stock.
Intensive aquaculture water accumulates dissolved organics, fine solids and microorganisms that can affect clarity, system stability and aquatic health.
An engineered ozone system treats a controlled side stream after suitable filtration and before water returns to the culture system. O₃ oxidises susceptible compounds and organisms, then is managed through contact, off gas handling and monitoring before treated water reaches the stock.
More About Ozone Generator for AquacultureThe treatment challenge
Four water quality pressures. One controlled approach.
Feed, waste and metabolic byproducts increase ozone demand and reduce clarity.
Small suspended particles can remain after basic mechanical separation.
Stock density, feeding rate and temperature can shift treatment demand quickly.
How O₃ works in aquaculture
From recirculation to controlled return.
Ozone treatment is engineered as a monitored side stream stage within the water loop and is not dosed directly into a culture tank.
- 01Draw a side stream
A controlled portion of recirculating water enters the treatment train.
- 02Remove larger solids
Mechanical filtration reduces solids and helps stabilise ozone demand.
- 03Generate and transfer O₃
Ozone is produced on site and dissolved through the selected injector and contact system.
- 04React and verify
Contact time, ORP and ozone monitoring support controlled oxidation and disinfection.
- 05Destroy residual and return
Residual ozone and off gas are managed before treated water returns to aquatic life.

Performance objectives
Useful outcomes. Clearly explained.
Oxidation can support the removal of colour forming and colloidal material.
Use controlled ozone contact against susceptible waterborne organisms.
Oxidise dissolved organics that contribute to colour and treatment demand.
Strengthen a suitably designed recirculating aquaculture treatment loop.
Generate the oxidant on demand instead of storing ozone or residual chemicals.
Monitoring and controlled treatment help operators respond to changing loads.
