For an SBR process, the sludge takes 45 minutes to settle and the depth of liquid in the reactor is 40% of the depth of the reactor after draw-off to prevent disturbing the settled sludge. The draw-off period takes an additional 20 minutes after the settle face. An idle time of 10 minutes is to be allowed. What is the required volume of each of the tanks in 2-tank and 3-tank SBR systems to handle a flow of 55000 M cubed per day to provide a react time of 60 minutes

The volume of a CFSTR is 45 m' and average constant flow in the reactor is 300 m /d. The reactor flow regime was established by feeding continuously 6 g/L stock tracer solution in the influent line at a rate of 125 L per day. Determine the theoretical tracer concentration in the effluent at 3 and 10 h after the tracer injection. Plot the tracer profile as a function of (a) concentration versus t, and (b) C/Co versus t/0.
A reactor with predominantly longitudinal dimension has reaction volume of 3,000 m3.The influent has flow rate of 600 m3/day and concentration of Na+200 g/m3 and BOD 200 g/m3. Please answer the following:a. What is the hydraulic retention time? b. What would be concentration decay model along the relative length x=L/L0? c. If it is an ideal plug flow reactor, please calculate the concentration profile along the length of the reactor, e.g., x=0.2, 0.4, 0.6, 0.8, and 1 of the total length if Na+ is a conservative species while BOD is degradable specie with reaction rate constant k = 0.4/day. d. Please plot the concentration profile vs. relative length x for Na+and BOD, respectively.

A treatment plant treats water at an average daily flowrate of 2.7 m3/s. The water is chlorinated before it flows into a 15000 m3 reservoir. The water flowing into the reservoir has a chlorine concentration of 3 mg/L. Chlorine decays at a rate of 0.24 h-1. Assume the reservoir is well-mixed and the system is at steady-state condition. (a) Determine the chlorine concentration at the discharge point of the reservoir. (b) The treated water flows from the reservoir into a transmission main. The pipe carrying the water has a diameter of 2 m and flows full. In the transmission main, chlorine decays at a rate of 0.19 h-1. Determine the concentration of chlorine 2 km from the treatment plant.
A full scale agitation system that has a flat blade turbine impeller with six blade-disk is used in a mixing operation. The (Da/W) and (D/J) values are 5 and 12, respectively. The liquid level is equal to the tank diameter. The liquid in the agitator has a viscosity of 85 cp and a density of 65.5 lb/ft³. The Reynolds number for the agitator is 10,000 and the agitator requires a power of 1 kW. It is desired to scale down the system for a vessel whose production volume is 4 times smaller than the original full scale agitation system. Assume mass transfer similarity for the scale down process. Calculate the power requirement in kW for the scaled down tank. Problem 2. 4

A storage tank of a treatment water has a holding capacity of 750 m' up to an overflow point. The treatment water having silica content of 0.003 mg /L is flowing in to a tank at a rate of 30 L/sec. the out flow from the tank to the high pressure boilers is 30 L/sec. With time the quality of treatment water increased to 0.025 mg/L. Assuming that the inflow in to and out flow from the tank remains constant at 30 L/sec, calculate the time required for the silica content in the storage tank to increase to 0.01 mg/L.
Environmental Engineering: A plug-flow reactor (PFR) has an influent flow with a concentration of 100 mg/L of A and a flow rate of 200 L/min.
