Ultraviolet Disinfection Provides Peace of Mind for Fish Farming Industry

Posted: Tuesday 1st December 2009

atg UV Technology, market leaders in Ultraviolet disinfection systems has supplied Halghton Fisheries, a leading Trout farm based in Wrexham, North Wales with a medium pressure UVL Ultraviolet disinfection system for its new Trout hatchery. The state-of-the-art atg UV Technology system will treat make-up water, sourced from a borehole supply before it enters the hatchery environment and will continue to provide disinfection on a recirculation loop to further prevent the risk of disease.

The UVL disinfection system provides protection against a range of Infectious diseases, in fish farms and hatcheries and has lead to the production of healthier and larger fish, improved water quality, increases in stock density and has vastly reduced the risk of low mortality rates.

Ultraviolet disinfection systems are perfectly suited to aquaculture applications as they are chemical free, automatic and cannot be overdosed, therefore maintaining the physical characteristics of the water such as PH levels and temperature whilst avoiding the introduction of harmful chemicals such as chlorine into the environment. Additionally Ultraviolet disinfection is non-selective in the destruction of all water borne bacteria, pathogens, viruses and micro-organisms. Organisms responsible for fish diseases that are treatable using atg UV disinfection systems are:

Pancreatic Necrosis (IPN) RNA-virus: Whirling disease: Viral Nervous Necrosis (VNN): Ulcerative Dermal Necrosis (UDN): Ichtyophthirius (white spot disease): Infectious SalmonAnaemia (ISA): Flavo Bacterium: Saprolegenia (fungal disease): Viral haemorrhagic septicaemia (VHS): Proliterative Kidney Disease (PKD): Vibrio Anguillarum.

The atg UV Technology solution comprised of a high quality UVL series reactor with a fully integrated NOVA control system. Automatic wipers were included to prevent the build-up of deposits on the quartz tube, and UV monitoring to ensure the systems consistently run at an optimum level. The NOVA control system provides operators with data on flow rate, UV dose and lamp intensity, whilst an in built in data logger can provide performance data which can be easily downloaded to a PC or Laptop for review.

atg UV Technology systems have been installed at numerous aquaculture application sites around the world including fish farms, mussel production sites, aquariums, lobster tanks and fish laboratories. With over 25yrs of experience and achievement, atg UV is a world leader in Ultraviolet technology. Strong commitment to innovation and development means that atg UV's range of Ultraviolet products offer customers the best choice available when quality, reliability and consistency need to come as standard.
