Contrast a Continuously Mixed Flow reactor and a Plug flow reactor and indicate under which circumstances each reactor will be applicable QUESTION 3 [20] Children exposed to high concentrations of manganese (>0.4mg/L) in drinking water have worse intellectual functioning than children with lower exposure. It is thus critical to remove Manganese (Mn) from drinking water. As an engineer, you know that the following reaction can be used as a first step toward removing Mn from groundwater. Chlorine dioxide (ClO2) reacts rapidly with Manganese oxidizing it to Manganese Dioxide (MnO2). Mn+2+2ClO2+4OHMnO2+2ClO2+2H2O Laboratory test has indicated that the pollutant concentration is 1.8mg/L 1) Confirm whether the above equation is balanced and provide your rationale (4) 2) Calculate the amount of O2 required to make water safe for human consumption. (10) 3) Calculate the amount of MnO2 Produced during the process (6)
