a) "Tertiary" and "Advanced" wastewater treatment processes are synonymous? Give valid reasons for your answer
b) Resolve Example NDMA (C2H6N2O) is a compound of concern present in many secondary and tertiary treated wastewater effluents. From Table 6-17, the second order rate constant of HO? for NDMA is 4 *10^8 L/moles. Compute the time required to lower the concentration of NDMA from 200 ug/L to 20 ug/L for a HO'? concentration of 10^-9 mole/L using an ideal plug flow reactor
c) Explain how the degree of NMDA (an organic pollutant) mineralization will be affected if the
(i) second order reaction constant is found to be higher than 4.8 x 10^8 L/mole.s
(ii) reaction was first order reaction with respect to hydroxyl radical
(iii) reaction was first order reaction with respect to NMDA concentration
(iv) concentration of the hydroxyl radical was increased (v) reactor was a completely mixed continuous flow reactor (vi) presence of cohabiting organic pollutants in the wastewater effluent
