Aquaculture Disinfection Systems

Aquaculture disinfection systems like RASLine UV are helping today’s fish farms tackle growing challenges. From higher fish stock densities and stricter environmental rules to rising resistance to traditional treatments. By replacing chemicals with powerful UV, these systems protect fish condition, support environmental goals, and help producers maintain profitability.

Chemical-Free Aquaculture Disinfection Systems

Evolving fish farming methods expose the limits of chemical disease treatments in meeting environmental standards.
RASLine UV helps aquaculture producers achieve disinfection without compromising health or compliance.

Eliminate pathogens without chemicals or antibiotics
Protect hatcheries and grow-out facilities
Maximise stock density safely
Comply with discharge and sustainability regulations

From inland tanks to offshore sites, UV safeguards stock health and water purity.

Purpose-built for aquaculture and backed by expert local support, RASLine UV protects your fish, brand, and profitability.

UV disinfection is increasingly critical in modern aquaculture, where chemical residues, pathogen resistance, and eco-regulations demand safer, smarter solutions.

With RASLine, aquaculture operators gain a reliable, scalable alternative that aligns with both biology and compliance.

Benefits of Aquaculture Disinfection Systems

Aquaculture disinfection systems safeguard fish health, support clean production processes, and protect the environment.

They are vital to maintaining health and efficiency in high-density operations.

By controlling microbial loads, they prevent disease, which can escalate quickly in confined environments and reduce the need for reactive chemical interventions.

This protects not only the livestock, but also water quality, downstream ecosystems, and operational compliance.

UV Disinfection Systems for Salmon Farming

Fish Farming UV solutions protects your fish, your processes and the environment

UV disinfection systems for fish farming protect livestock, operations, and aquatic environments.

With growth in stock density and stricter regulations, salmon farms urgently need chemical-free disinfection to control disease and meet environmental goals.

In salmon aquaculture, waterborne pathogens pose a significant risk to fry and smolt development.

UV disinfection systems provide a consistent, non-chemical method to neutralise viruses, bacteria, and parasites before they can spread.

By integrating UV at key treatment stages, producers reduce cumulative mortality, support welfare targets, and ensure stable yields.

Frequently Asked Questions – UV Disinfection for Aquaculture

Find answers to your key questions below

How do Aquaculture Disinfection Systems improve fish-farm health?

UV light from Aquaculture disinfection systems provides a reliable, chemical-free barrier against water-borne pathogens. This approach reduces disease, improves survival and lessens antibiotic use, trimming costs and ecological harm.

How do Aquaculture Disinfection Systems use UV to purify water?

Water passes through a stainless-steel chamber fitted with low-pressure lamps that emit germicidal 254 nm UV-C energy.

These photons disrupt microbial DNA and RNA, stopping reproduction yet preserving water chemistry, flavour and odour.

Which pathogens do Aquaculture Disinfection Systems neutralise?

UV doses of 25–40 mJ cm⁻² disable key RAS pathogens, including Aeromonas, Pseudomonas and Vibrio.

They also neutralise IPN viruses, Saprolegnia fungi and protozoan parasites such as Ichthyophthirius.

Will UV treatment affect fish or water quality?

No. UV is a purely physical process that adds nothing to the water and creates no disinfection by-products. Parameters such as pH, salinity and dissolved oxygen remain unchanged, so fish experience zero chemical stress.

Can Aquaculture Disinfection Systems work alongside ozone or other treatments?

Yes, many farms place UV after ozone: it delivers the final pathogen kill and eliminates leftover ozone, boosting safety for staff and stock.

What flow rates can Aquaculture Disinfection Systems from Nuvonic handle?

Modern reactors span 35 m³ h⁻¹ in hatcheries to 3 500 m³ h⁻¹ on large RAS or intake lines.

Automatic dose control trims energy use across the range.

How do I size an Aquaculture Disinfection System for my facility?

Engineers match lamp power, lamp count and chamber design to peak flow, UV-transmittance and target dose.

Typical doses are 25 mJ cm⁻² in clear RAS water and up to 40 mJ cm⁻² when UVT drops below 85 %.
