It is required that a wastewater flow of 2 MGD with a strength of 300 mg/L BOD5 be treated to remove 90% of the BOD5. To achieve this, a 25-ft deep filter will be constructed and plastic media will be used. A treatability study has shown that n = 0.5 and K= 0.05 min-1 at 20⁰C. If the critical wastewater temperature is expected to be 10⁰C, what size filter should be required? Recirculation will not be used. Use Excel and...

We are trying to remove tetrachloroethene (C_2Cl_4) from ground water by air stripping process. The maximum level of tetrachloroethene in the ground water is 5 mg/L and this must be reduced to 50 mu g/L using air stripping column. Here is given information; Liquid-phase mass transfer (m/sec) kL = 19.86 times 10^-4 m/sec Wetted packing area (m^2/m^3), a_w = 89.18 m^2/m^3 gas-phase mass transfer (m/sec), k_G = 4.94 times 10^-3 m/sec liquid flow rate, Q_w = 8L/sec Temperature = 6...

For each filter mentioned in the following cases, first simulate the circuit using Multisim. You can get a plot of the transfer function that is called the Bode plot. From the right toolbar, select "Bode Plotter". Change initial (I) and final (F frequencies to 1Hz and 200 KHz, respectively. Use a Voltage AC source as the input signal. You do not need to change any parameter from voltage AC source Connect "Bode Plotter" to input and output of your circuit...

Name: ID: 2. The activated sludge process can be used to remove organic carbon (BOD) and nitrogen species (ammonia, nitrite and nitrate) from wastewater. The schematic below is a of the 4-stage Bardenpho process that can achieve low levels of ammonia and nitrate in the final effluent). Please describe how BOD and nitrogen species concentrations evolve in each stage, include what the return activated sludge, the internal mixed liquor return, and the methanol injection are used for.
