METHOD AND SYSTEM FOR OXYGEN ENRICHMENT OF WATER USED FOR ANIMAL DRINKING OR IRRIGATION

Claims

Installation for oxygenating water used for irrigating crops or for watering animals (40), comprising means for transporting water to the animals for watering or to said crops, wherein said transport means comprise: - an injector (7, 8) for injecting a gas into the water; - a water inlet line (20) and at least one gas inlet line (3, 4, 5, 6) entering the injector; and - at least one source (1, 60) of oxygen or of a gas mixture including oxygen, capable of supplying oxygen to the gas line; - a tank (17) of water at atmospheric pressure, to which water is supplied to the injector from the water in this tank, where fresh water (20) can also be supplied; - a coil (10) capable of receiving water charged with dissolved oxygen from the injector, wherein said water reaches the coil by means of a pump (9), and said coil creates a water / oxygen contact time;wherein said source is an oxygen concentrator (60) that supplies oxygen-enriched air; characterized in that the installation includes a water pressure sensor (90) on the discharge side of the pump, as well as a water flow sensor (80), preferably installed on the discharge side of the pump, wherein the flow sensor authorizes the electrical activation of the concentrator when the pump is started, while, when the pressure at the pump outlet rises to a desired pressure set point, the pressure sensor authorizes the opening of a solenoid valve (5) located between the concentrator and the suction side of the pump.
