摘要：The purpose of this study was to determine the effectiveness of aeration with the use of an applier (a device for aeration of sludge protected by the patent application no P-416711) by determination of characteristics of its operation depending on the stream of water flowing through the device, the height of the outlet over the water table and multiplication factors of measuring water pumped through the applier. On the basis of laboratory tests/measurements, a mathematical model of the increased concentration of oxygen dissolved in water has been developed.
其他摘要：The purpose of this study was to determine the effectiveness of aeration with the use of an applier (a device for aeration of sludge protected by the patent application no P-416711) by determination of characteristics of its operation depending on the stream of water flowing through the device, the height of the outlet over the water table and multiplication factors of measuring water pumped through the applier. On the basis of laboratory tests/measurements, a mathematical model of the increased concentration of oxygen dissolved in water has been developed. As a result of the research, a significant increase in oxygen concentration has been achieved only after the first water pumping through the applier. The determined mathematical model can be used to calculate predicted increases of oxygen concentration dissolved in water in variants other than those investigated.
