    Ultraviolet Disinfection for Aquaculture

    The use of atg UV Technology Ultraviolet disinfection systems in fish farms, mussel farms, aquariums and hatcheries has lead to the production of healthier and larger fish, improved water quality, possible increases in stock density and vastly reduces the risk of disease. atg UV Technology`s disinfection systems 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 toxins such as chlorine into the environment. Ultraviolet disinfection is non selective in the destruction of all water borne bacteria, pathogens, viruses and micro-organisms.

  • Wastewater treatment for the canning and fish industry

    The waste water from these companies usually has a high demand in oxygen chemistry (DOQ), normally due to proteins and fats. They have high concentrations of chlorine, sulphate and sodium because, in many cases, the processes involve seawater.

  • Water quality monitoring for aquaculture industry

    A clean and pathogen free water source is essential to prevent infections from being introduced and spreading in a hatchery. Ultraviolet (UV) disinfection of water for inactivation of pathogens is recognized as a safe and effective method for use in the aquaculture industry. Continuous monitoring of water quality by measure of UV transmission (UVT) ensures the UV light is able to penetrate the water effectively and achieve the optimal dose.

  • Ozone Water Treatment for Aquaculture

    Three reasons why ozone in aquaculture improves water quality and increase aquaculture productivity. As recirculating aquaculture systems (RAS) operate by reusing the fish tank water it is essential to control the water quality. Many studies show that treating RAS systems with ozone increases productivity as fish health and survival is increased.

  • Water Recirculation System for Fish Farming

    Research project where no chemicals are used in water treatment and water is only added to replace any evaporated water. The fish are grown in a tank with closed water circuit. The waste produced by fish are utilized by growing algae. The grown algae are returned for fish feed. Our method allows efficient and environmentally friendly fish farming that can be placed near the consumer.

  • Wastewater Treatment for Aquaculture

    Wastewater treatment for aquaculture will typically consist of processes for removal of major pollutants such as organic matter, suspended solids, ammonia nitrogen, dissolved gases and bacteria/virus. Typical unit processes may include: Biological treatment Solids removal Disinfection

  • Aeration of Crayfish Basins

    Crayfish is a very demanding species when it comes to the quality of water. One of the most important facts is the sufficient content of oxygen concentration in water. Actually the crayfish is just as demanding as salmonoids about oxygen content. During warmer seasons oxygen content of the water should be at least 5 mg/l (oxygen saturation at least 50 %). In the winter the crayfish can adapt to short periods with 2 – 3 mg/l content if all the other environmental conditions are favorable.

    Crayfish basins are rather small usually, so Waterix AIRIT® Micro is an excellent choice. The device is lightweight but boasts exceptionally high operating efficiency and output. AIRIT® Micro ensures oxygen content throughout the crayfish basin is always in excess of 5 mg/l. This enables the crayfish maturity period to be perfect in respect to oxygen content.AIRIT® Micro can be used throughout the year or when the water starts to stratify.

  • Ozone generator

    The irrigation with ozonized water systems consists on providing a greater amount of oxygen to the root arriving free of virus, bacteria, fungi, seaweed, spores and any other microorganism, reason why it is obtained a faster growth than the habitual one, with more aliveness and force as well as more productivity. This system is very beneficial for the irrigation, such as fruit trees, vineyards, and cultures in general obtaining the prevention of diseases in the plants. Ozone has an oxidizing power greater than the Oxygen one, so for that reason it improves the respiratory process at cellular level. The direct germicidal action of Ozone is also well-known against all type of microorganisms, as much fungi as bacteria and virus.

  • Monitoring Equipment for Fish Farms

    OxyGuard was founded as the first company in the world dedicated to providing metering, monitoring and control equipment to fish farms. The oxygen probes and multi-channel systems were revolutionary, and helped fish farming grow into the Aquaculture Industry that it is today. 

    Whether you need a hand-held DO meter or a system that can control your entire fish farm, OxyGuard equipment will help you run a profitable business. The return on investment time for OxyGuard equipment is short, even if you already monitor water quality the improved accuracy and stability of OxyGuard DO probes and control systems will give you considerable benefits.

    OxyGuard gained a reputation for excellence that led to a demand for other products and from other markets, but the company`s main focus is still on aquaculture. Improvements and the introduction of new technology have taken place, but the company philosophy is still to provide the fish farmer with precisely the equipment that is needed.

    Previously a simple oxygen measurement was enough - this is not the case today. The Aquaculture industry has grown; the demands to fish farming methods and the equipment used have grown with it. OxyGuard have designed the Commander system to meet these demands - and have made sure that Commander has the scope and flexibility to meet future demands.
