2. Ferrous iron (Fe2+) must be removed from a steel plant wastewater to meet a pretreatment standard of 106 M. The proposed treatment scheme involves oxidizing the ferrous iron to ferric iron (Fe³+) in a CMFR. The ferric hydroxide precipitate (Fe(OH)3(s)) will be continuously removed from the bottom of the reactor to maintain steady state conditions. Dissolved oxygen will be added to the reactor by bubbling air through the solution. The pH in the reactor will be kept constant by the addition of a well-buffered caustic waste stream from another part of the plant. You are given the following information: Temperature=20 °C Waste stream flow rate Caustic stream flow rate = 1000 L/min = 100 L/min Concentration of Fe²+ in the waste stream=5x10-3 M Volume of reactor-72,500 L Saturation concentration of oxygen at 20 °C = 9.08 mg/L = 2.84x104 M Constant pH in the reactor = 9 Assume that there is no dissolved oxygen in either the waste stream or the caustic stream. The reaction occurs in two…

In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours  Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99

Determination of Total Chlorine Residual Description of the MethodThe chlorination of a public water supply produces several chlorinecontaining species, the combined concentration of which is called the total chlorine residual. Chlorine is present in a variety of chemical states, including the free residual chlorine, which consists of Cl2, HOCl and OCl–, and the combined chlorine residual, which consists of NH2Cl, NHCl2, and NCl3. The total chlorine residual is determined by using the oxidizing power of chlorine to convert I– to I3-. The amount of I3- formed is then determined by titrating with Na2S2O3 using starch as an indicator. Regardless of its form, the total chlorine residual is reported as if Cl2 is the only source of chlorine, and is reported as mg Cl/L. The description here is based on Method 4500-Cl B as published in Standard Methods for the Examination of Water and Wastewater, 20th Ed., American Public Health Association: Washington, D. C., 1998 ProcedureSelect a volume of…
