Aquaculture UV Water Treatment System

UV Guard supplies reliable, chemical-free aquaculture UV water treatment systems to protect fish, shellfish and crustaceans across every stage of farming. Our aquaculture UV water treatment systems improve biosecurity, support compliance with aquaculture standards, and help maintain healthy aquatic environments in both freshwater and marine operations.

Reliable UV Water Treatment Solutions for Aquaculture

Poor water quality is one of the most common causes of health issues in aquaculture. Whether the problem starts at water intake, recirculation, or discharge, it can lead to disease outbreaks and stock losses. UV Guard’s aquaculture UV water treatment solutions offer a chemical-free way to minimise these risks, improve survival rates, and maintain consistent water conditions.

UV disinfection works by inactivating microorganisms, such as bacteria, fungi, viruses and protozoa, without the use of chlorine or ozone. There are no known aquaculture pathogens that are resistant to UV, making it an effective tool across all environments. From Recirculating Aquaculture Systems (RAS) to hatcheries and well boats, a UV system provides an added layer of protection without harming fish or altering water chemistry.

Every aquaculture site is different. To match the UV system to the specific water conditions and flow rates, we carry out UV Transmittance (UVT) testing in our lab. This testing informs the UV dose required for reliable disinfection and helps us select the most suitable system from our range:

  • Armour Series: Designed for durability in harsh marine and industrial environments.
  • S Series: Modular systems suited for mid-to-large scale installations.

These aquaculture UV steriliser units are built to deliver safe, consistent disinfection for operations working with freshwater, brackish or seawater.

Aquaculture Applications

  • Improve fish, crustacean and shellfish quality and yields using aquaculture UV water treatment to minimise exposure to waterborne pathogens.
  • Ensure Recirculating Aquaculture Systems (RAS) remain free from contamination using purpose-built aquaculture UV water treatment systems that support higher stocking densities.
  • Safeguard hatcheries, larvae and fry with non-chemical disinfection at this critical stage of development.
  • Protect fish stocks in marine well boats by disinfecting water used during transport between farming sites.
  • Allow aquariums and zoos to provide safe, clear aquatic environments for marine life and the visitors who come to see them.

  • Stopping the spread of viruses in aquaculture research facility

    The aquaculture facility had multiple research stations all independently researching different fish species at the same time, and each one of these stations required its own UV system to treat the water entering that specific area. Additionally, all seawater entering the research facility needed to be treated. All UV systems needed to be selected to achieve minimum UV doses to achieve sufficient inactivation of viruses such as white spot.

  • Underwater World – UV disinfection for sea water aquarium

    Underwater World in central Mooloolaba, located in the heart of Queensland’s famous Sunshine Coast is renowned for being the area’s top family attraction. The aquarium is home to a range of marine life including fish, sea animals and corals. The marine life must be protected from a range of diseases including bacteria, fungi, viruses and protozoa.

Frequently Asked Questions (FAQ)

By inactivating pathogens in the recirculating water, a aquaculture UV steriliser reduces the risk of disease and stress on fish. This creates a healthier environment that can lead to improved fish health, higher survival rates and faster growth.

No. UV systems are generally low-maintenance. The main requirement is a periodic cleaning of the quartz sleeve and an annual lamp replacement to ensure effective performance.

No. UV disinfection is a chemical-free process that does not change the water’s pH, taste, odour, or chemistry. This means the overall water quality in your RAS remains stable and is not altered by the treatment.

Shrimp are highly susceptible to viruses and bacteria. A UV water treatment helps safeguard shrimp by ensuring their water supply is free of these microorganisms at every stage of the farming process, from hatchery to harvest.

Yes. Aquaculture UV water treatment systems are effective for both disinfecting incoming water to prevent outside pathogens from entering the system and treating outgoing discharge water to prevent the spread of pathogens to the surrounding environment.

UV disinfection is a physical, chemical-free process that does not produce any harmful by-products. Chemical methods, while effective, can leave residuals that may be toxic to fish and require careful dosing and handling.

Yes. While the initial investment may be higher than chemical dosing, a UV water treatment is cost-effective over its lifespan. It requires minimal energy and reduces ongoing costs associated with purchasing and handling chemicals.
