EQUIPMENT FOR KEEPING WATER ORGANISMS Russian patent published in 1997 - IPC

FIELD: agriculture, pisciculture. SUBSTANCE: equipment consists of the main circulatory contour that includes a tank full of water for water organisms, a pump, mechanical filter, water purification system with biofilters and an oxygenator, water preparation system, device to correct acidity of aqueous medium, and regulatory system. As for water preparation system it is a self-circulatory contour connected with the main circulatory contour and contains water collector, a pump and a set of electrolyzers. Device to correct water acidity contains tanks for electrolytic water fractions connected with electrolyzer and main circulatory contour. Installation contains closed circulatory contour of liquid fluororganic compound - oxygen carrier - that consists of a pump, mechanical filter, degasifier and opened trays for water organisms to provide gas exchange for water and organofluoric compound. It is useful to complete water purification system with denitrifier. EFFECT: improved conditions for keeping water organisms due to possibility to use natural water of any hardness level, more safe water acidity correction, higher efficiency of water saturation by oxygen and high-quality biological water purification. 2 cl, 1 dwg
