ABSTRACT:
A system for the treatment of liquids, especially oxygen enrichment of water which is used for aquaculture purposes such as the breeding of fish, avoids gas bubbles in a water reservoir and makes it possible to freely treat fresh water and/or recirculated water for optimal temperature control and/or water removal. A water flow is joined with a flow of pure oxygen gas which is supplied from an oxygen tank containing liquid oxygen. The oxygen is led through an evaporator into a flow system forming a recirculating circuit with pipelines, and an oxygen enrichment device or reactor unit where water and oxygen are mixed to form a turbulent, foaming gas/liquid flow mixture. Such mixture is subsequently led into a gas/liquid separator where gas and liquid are separated. The gas mixture from the separator, which now in addition to oxygen also will contain contaminants such as nitrogen and carbon dioxide, is recirculated by means of a compressor. To prevent the build-up of great amounts of nitrogen and other contaminants, there is provided a deaeration device in the form of a bleed or in the form of a special separation unit.
