UV / Ozone Disinfection
UV and ozone systems for pathogen control and biosecurity in commercial RAS loops.
What Problem It Solves
Pathogen introduction and proliferation can devastate intensive aquaculture operations without effective disinfection barriers.
Position in a RAS Flow
Applied on loop branches, intake water, or batch treatment lines depending on biosecurity zoning strategy.
How It Works
UV irradiation inactivates microorganisms by damaging DNA/RNA. Ozone oxidizes organic matter and pathogens, with residual control via ORP monitoring and deozonation before fish contact.
Key Design Considerations
- •Match UV dose to target organisms and flow rate
- •Ozone requires careful residual control and off-gassing
- •Separate loops for nursery vs. grow-out when needed
Common Mistakes
- •UV lamps not maintained leading to dose failure
- •Ozone overdose causing gill damage
- •Disinfection without addressing source biosecurity

Shrimp RAS Project Story
High disease pressure and inconsistent results in open pond production led the client to seek a biosecure indoor RAS with clearer batch control and export-oriented traceability.
A clear-water RAS with segregated nursery and grow-out loops, enhanced mechanical filtration, biofiltration sized for shrimp loading, UV/ozone disinfection barriers, and centralized monitoring for critical parameters.
Hatchery & Nursery Project Story
Inconsistent larval survival and unstable water quality during nursery phases affected production planning. Existing equipment was fragmented with limited automation.
TurnkeyRAS upgraded the treatment loop with refined mechanical filtration, expanded biofiltration capacity, precision oxygenation with supersaturation safeguards, and ozonation with ORP-controlled dosing.
