Transcribed Image Text:

Laboratory test reactors have been operated at different SRT values at steady state to obtain biological kinetic coefficients for a wastewater with soluble constituents only. The reactors are complete-mix and aerated with clarifiers and solids recycle. The T value in all cases is 0.167 d and the SRT values were varied for the five tests. The influent and effluent soluble bCOD and reactor MLSS concentrations are summarized as follows: Test No. SRT (d) So (mg COD/L) S (mg COD/L) X (mg VSS/L) 1 3.1 3950 2 2.1 2865 3 1.6 2100 4 0.8 1050 5 0.6 660 c) Mm d) Y e) b 400 400 400 400 400 10.0 14.3 21.0 49.5 101.6 From the above data, determine the values for the following biokinetic coefficients: a) k b) Ks Note: (1) Change the equation format so that linear regression can be used to estimate the kinetic coefficients. (2) Calculate the solids production at each SRT value.
