recirculating aquaculture system Applications

  • 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.

  • 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.

    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.
