Abstract: A system for degassing water is described. It uses multiple stages starting with an aerator connected to a number of pumps which conveys water to various filters and tanks. The water is received in at least one buffer tank for de-ironed water which is connected to a fourth tank which can include an ozonization system. At least one buffer tank is connected to a water pressure degassing system pumps water to a fifth tank fitted with a vent and a relief system. This fifth water tank is connected to an aeration pump having an air sterilizer and the aeration pump. It is connected to a parallel system comprising an inflow collector, flow meters, flow regulating valves, at least one aeration tank having permanent magnets, pipes and an outflow collector which is connected to a final tank and filter from which water is fed into a bottling machine.
