Question
The following data was obtained from a test program designed to evaluate a new diffused-air aeration system. Using these data, determine the value of KLa at 20oC and the equilibrium dissolved-oxygen concentration in the test tank. The test program was conducted using tap water at a temperature of 24oC.
C, mg/L | 1.5 | 2.7 | 3.9 | 4.8 | 6 | 7 | 8.2 |
dC/dt, mg/L.h | 8.4 | 7.5 | 5.3 | 4.9 | 4.2 | 2.8 | 2 |
If the volume of the test tank used to evaluate the aeration system were equal to 100 m3 and the air flowrate were equal to 2 m3/min, determine the maximum oxygen transfer efficiency at 20oC and 1.0 atmosphere.
