  • Onsite Oxygen Technology for Aquaculture

    OGSI Leads the Way in Onsite Oxygen Technology for Aquaculture The OGSI oxygen system is an efficient and cost-effective means by which to increase the dissolved oxygen (DO) level in an Aquaculture system. The system was developed by OGSI. It enables fish farms to dissolve oxygen in any size tank. Farms are able to increase stocking densities. The fish are also healthier and have better taste when raised in an oxygen rich environment.

  • Oxygen Generation for the Aquaculture Industry

    For more than a decade Oxymat has been the preferred oxygen supplier to all major fish farms within recirculation technology. Knowing fish farming to the bone; Pure oxygen is essential in all modern fish farming. Pure oxygen dosed in correct way ensures faster growths rates, better FCR, less stress and diseases and better prices selling the fish due to higher quality. We understand the environment of fish farming and the need for a 100 % reliable oxygen source. Oxymat has delivered oxygen generator systems for more than a 200 fish farms worldwide both for recirculation, flow through and to wheel boats.

    Special Know-How & Services from NOXERIOR

    We at NOXERIOR are perfectly aware that oxygen is a variable cost for your hatchery operation. A reliable estimation of oxygen requirements and a correct dimensioning of an oxygen generation system from our OXYSWING® PSA oxygen generator product range will be determining for the economical benefits you expect from an on-site oxygen generation and supply system in your hatchery.

    We will provide consultancy regarding the most efficient oxygen distribution as well as technology for oxygen transfer and regulation into water under consideration of all relevant parameters. By using our in-house developed software we can calculate both the required amount of oxygen to be produced and the resulting energy consumption. Together with you will find a compromise between the use of energy and the efficiency of oxygen transfer to optimise costs.

  • Premium

    Aeration and mixing technologies for aquaculture

    Maintain healthier ponds, increase stocking densities, and generate higher yield with optimum oxygen transfer. Maintaining the proper level of oxygen dispersion in your systems is critical to the success of your operation – and the life of your fish. Poor dissolved oxygen levels, fluctuating water temperatures, and stratification all can negatively affect fish health and pond production.

  • 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.

  • Gas infusion technology solutions for the aquaculture industry

    The PurGRO2 iLS gas transfer system is unique in its ability to create and maintain stable "controlled atmospheres" in water. This patented system and technology deliver signifi cant added value to multiple markets. In aquaculture, where oxygen is the source gas, PurGRO2 iLS creates and maintains an atmosphere in fresh and salt water of stable dissolved oxygen, at normal total gas pressures. Unlike more conventional forms of oxygenation, PurGRO2 is temperature independent, and actually delivers more oxygen with higher water temperatures.

  • 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.

  • Geomembranes for Shrimp Farming Ponds

    Intensive commercial shrimp farming began in the late 1960s led in part by technological advances and growing market demand. Today, shrimp farming is so intensive (in some cases close to 300 000 shrimps per hectare) that it requires industrially prepared shrimp feeds, fertilizing the ponds to stimulate the growth of organisms, aeration to prevent oxygen depletion and regular tidal water exchange.  Solmax geomembranes have been used in some of the largest shrimp pond projects in the world. There are several key benefits of lining shrimp ponds with geomembranes. Durable and robust, the HDPE surface prevents weeds, grasses, mud and other obstructive contaminants from entering the pond.  The HDPE substrate is known to reduce the suitability of the environment for bacteria thereby reducing the need for antibiotics. Geomembranes can also protect the slopes and banks from erosion and allow for easy detection and rapid removal of sediment and waste products.

    Here are several factors to consider when deciding which type of geomembrane to use in a Shrimp Pond application:

    • Stress crack resistance
    • Tensile and elongation properties
    • Tear and puncture resistance
    • Duration of the project
    • U.V exposure

    Please contact us if you need technical support or need to speak with a sales representative.

  • 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.

  • 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.
