WATER OXYGENATION AND SYSTEM OF AQUACULTURE

摘要

Low pressure oxygenation of a flow of water, for example useful in providingoxygenated water in aquaculture systems for raising fish, involves providingan enclosed chamber (28) to which oxygen is supplied at atmospheric pressureand delivering a continuous flow of water into the upper region of thechamber. The water is sprayed onto a diffuser (50) which breaks up the waterflow to produce a spray of droplets and foam which mix intimately with theoxygen atmosphere as the water spray drops downwards. Oxygenated water fromthe lower end of the chamber is delivered to a pond to supply oxygen that isusable by fish being raised in the pond.
