Water Retention with Zero Order Reaction
Posted: Sat Oct 14, 2023 1:26 pm
I have one of the equations to solve this problem but how would I determine the slope of the line in [A] = [A]o - kt? I'm also familiar with rates of change in calculus, etc, it's just been a while since I've taken this.
3-29 from Textbook. A strain of bacteria has been isolated that can cometabolize
tetrachloroethane (TCA). This strain of bacteria can be used for the bioremediation of
hazardous-waste sites contaminated with TCA. Assume that the biodegradation rate is
independent of TCA concentration (i.e., the reaction is zero order). In a bioreactor it is
observed that the rate for TCA removal was 1 µg/L-min. What water retention time
would be required to reduce the concentration from 1 mg/L in the influent to 1 µg/L in
the effluent of a reactor? Assume the reactor is completely mixed.
