and rejected product streams.When the tank is filled, mixers are activated and its contents are vigorously mixed. While mixing continues, a strong oxidant is added in excess to reduce the TOC of the tank contents to less than 100 mg/L. The tank contents are then discharged to a central biological treatment facility. The oxidation process is known to be first-order in TOC, with an empirically correlated rate coefficient of k = 2.5 x 10-3(TOC), per day. For a starting concentration of 12,500 mg TOC/L, determine the minimum reaction time interval required to meet the pre treatment objective. Comment on why in this type of situation k might in fact be found to correlate with the initial TOC concentration.
