Of these amounts of air brought to the water by the Hydro-air-ejectors, only 21% is oxygen and the rest nitrogen and other noble gases which are in the atmosphere. Therefore, in calculating the amount of O2 necessary for the total volume of water to be treated, the information on the air provided by the Aerator must be taken into account (1 Submerged Aerator = 2 Hydro-air-ejectors), as well as the number of hours per day that it will function. It must also be taken into account that most of the water transferred to the pond rises through the water to the surface where it evaporates. Therefore it is necessary for the function time of the aerators to be at least 4 times that of the results obtained with the previous data.
