UV Systems for Aquaculture Intake Water


ACN ULTRABARRIER™ – Optimized FIREWALL technology for intake water UV disinfection.

UV system series ACN ULTRABARRIER™ was engineered specifically for intake water in the aquaculture sector. The unique shape, achieved through the meticulous development process, helps to increase the performance of hydraulics, significantly reduce head-loss and eliminate dark areas. Depending on the source of intake water – options for stainless steel AISI316L (SS) and corrosion free polypropylene (PP) are available.

DVGW/ÖNORM validated Duplex UV sensors

Certified DVGW/ÖNORM UV sensor guarantees secure water disinfection for any situation. ACN ULTRABARRIER™ series for intake water comes with two ÖNORM validated UV sensorsThis enables the system to continuously regulate the dose of UV and ensure high biosecurity standard in the fish farms.


Wiper systems by ULTRAAQUA UV are fully automated cleaning systems designed to last even in salt environments. A compact design allows full access to lamps and quartz and changing the wiper rings can be done in a few minutes without tools. The cleaning interval can be adjusted to suit the application demand and extend the lifetime of components.

Norwegian Veterinary Institute Approval

ULTRAAQUA UV systems are approved by the Norwegian Veterinary Institute – a biomedical research institute and the national leading center of expertise in biosecurity of fish and land animals. This makes ACN ULTRABARRIER™ UV systems particularly suitable for intake water application in the aquaculture industry.

ACN ULTRABARRIER™ UV systems features:
  • Dose control/pacing

Norwegian Veterinary Institute

One entirely product series is approved by the Norwegian Veterinary Institute (NVI) for intake water application in the aquaculture industry

Certified DVGW/ÖNORM Double UV sensor system guarantees secure water disinfection for any situation.

High minimum UV dose

Depending where the water is sourced it may contain living microorganisms.
Different sources: rivers, ponds, borehole, public water. Effective UV creates UV firewall and ensures that no harmful microorganisms enter to the RAS. High minimum UV dose typically from 100 mJ/cm2 to 300mJ/cm².


High hydraulic efficiency ensures efficient disinfection and reduced total number of UV lamps. UV Lamps are installed closer together reduce dark areas and to guarantee high minimum UV dose for microorganisms even in turbid water.

Intake water FIREWALL UV design

ULTRAAQUA ACN ULTRABARRIER™ series ensures no organisms entry to the RAS system. Based on two UV-sensor measurements and flow-rate input, control system checks that current flow is below acceptable level in order to maintain the target minimum UV-dose.
