Reactors in series You are considering available options to meet new effluent quality standards for a particularcontamination being treated at your plant. Currently you are operating with two reactors connected inparallel as shown in Figure 1(a). One reactor is a plug flow reactor (PFR), the other is a completelystirred tank reactor (CSTR). The following information is available:Design flow, Q:60 L/minInfluent concentration, Co:10 mg/LOrder of reaction:1st OrderDecay constant, k:0.25 min!Volume of PFR, Vp:360 LVolume of CSTR, Vc:2280 LUsing the above information, determine:a. The residence time, t, in each reactor;b. The effluent concentration from the PFR;C.The effluent concentration from the CSTR.d. The resulting effluent quality with the two reactors in parallel.You want to investigate whether operating these reactors in series will allow the required effluentstandard of 0.25 mg/L to be met. You are therefore proposing the new configuration for the reactorsshown in Figure 1(b)Determine whether the plant will be able to meet the effluent standards.

An activated sludge treatment process uses a rectangular tank that can be modeled as two completely mixed reactors in series. The volume of the tank is 300 cubic meters (for modeling purposes 150 cubic meters each) and the flow rate into the system is 900 m3/day.

An activated-sludge system is to be used for secondary treatment of 15,000 m3/d of municipal wastewater. After primary clarification, the BOD is 130 mg/L, and it is desired to have not more than 5 mg/L of soluble BOD in the effluent. A completely mixed reactor is to be used, and pilot-plant analysis has established the following kinetic values: Y = 0.6 kg/kg, kd = 0.07 d-1. Assuming an MLSS concentration of 2,750 mg/L and an underflow concentration of 11,000 mg/L from the secondary clarifier, determine the followings. [Use θc (MCRT or SRT) = 10 day.] 5.1. The volume of the reactor. 5.2. The mass and volume of solids that must be wasted each day. 5.3. The recycle ratio. Hint: θc = VX/QwXu : MCRT (mean cell-residence time) [or SRT (solids retention time)]; average time microbes spend in reactor = ratio of total biomass in reactor to biomass wasted per given time; currently most commonly used design parameter F/Mv: inversely proportional to SRT; ≈U (cell's specific substrate…

You have been treating a wastewater with bacteria that have the following kinetic coefficients: k= 16 mg BODL/mg VSS-day Ks = 10 mg BODL /l b =0.2/day Y = 0.35 mg VSS/mg BODL fd = 0.8A genetic engineer comes to you and claims he can “fix” your bacteria so they are more efficient. The fixed bacteria will have b=0.05/day and fd = 0.95, while all other coefficients are the same. Using a chemostat reactor, you were successfully using a safety factor of 30, and you plant to continue doing so.
