In a pressure storage room, the water level in a water/air container 1 is controlled by activating a water pump 3 with a level indicator 8. A minimum pressure in the air quantity 14 in the container 1 is maintained by introducing compressed air from a compressed air source 15 - 19 containing a pressure reducer valve 19 with check valve function. An installation using this control method permits water treatment with oxygen gas from the air by arranging an air intake connection 27, 28, 29 between the air quantity 14 in the container 1 and the water pumped in by the pump 3. <IMAGE> |
