How to reduce the agitation caused when using the stir tank bioreactor to produce CAR T cells in bioreactor system
An activated sludge system using CSTR with sludge recycle has an influent flow rate (Q°) of 2.5 MGD that contains BOD of 200 mg/L. The volume of the aeration tank (CSTR) is 0.6 million gallons. The MLVSS (assume this is X,) in the aeration tank is 2000 mg VSS/L and the decay rate (b) is 0.1/day. The effluent from the secondary clarifier meets NPDES standards for suspended solids and BOD. The concentration of the settled sludge exiting the bottom of the secondary clarifier is 15,000 mg VSS/L. The sludge waste flow rate (Q") is 1 % of the influent flow rate, and the effluent flow rate (Qª) is ~99% of the influent flow rate. а) What is the hydraulic retention time, 0 (d)? b) What is the solids retention time, 0x (d)? Activated sludge with recycle с) What is the F/Ma ratio?
Given a 2° standard gauge, the maximum speed of 160 km/h and the equilibrium superelevation as decided by the chief engineer is 90 km/h. The Cant deficiency (mm) most nearly: ???
In a municipal wastewater treatment plant, the influent flow rate into a complete mixing activated sludge system is 50 L/sec, its solid concentration MLSS is 30 mg/L, and the BODs in the influent is 245 mg/L. The MLSS concentration at the bottom of the secondary clarifier is 15,000 mg/L and 10 mg/L at the top of the |clarifier. The flow rate of returned activated sludge is 20 L/sec. a. What is the concentration of the MLSS in the activated sludge reactor (assuming that it is fully mixed and has constant concentration)? b. What is the activated sludge basin volume if the hydraulic retention time in the basin is 10 hours and the system is operated at the R/Q ratio given in the problem? |c.

The operation used to separate a liquid-liquid mixture is: A) Filtration B) Extraction C) Crystallization D) Adsorption Answer fast
1a. In water and wastewater containing particles that tend to coalesce upon colliding with other particles, and having a range of particle sizes, fast settling larger particles overtake slow settling smaller particles (in accordance with Stokes' law) possibly colliding and coalescing with these smaller particles. Under these conditions, particles tend to grow in size and settle at still higher downward velocity. This is known as __________ settling. b. Based on concentration and the tendency of particles to interact, particle settling in a water or wastewater clarifier can be described as: a) compression b) discrete particle settling c) Any or all of these types of settling may occur in a single clarifier d) hindered (also called zone) settling e) flocculent settlin ? ? c. Rectangular clarifiers typically use either chain-and--------- or traveling- ----------type sludge…
A Granulated Activated Carbon (GAC) adsorption laboratory column 10cm in diameter and 3m deep, is found to produce good results in COD removal when operated at a flow of 50L/h. The porosity of the GAC is 0.5 Calculate the following: The application rate in m/h. The residence time, t, in the column. The volumetric flow rate, Vb, in bed volumes per hour, for this residence time. You need to design a GAC system consisting of two columns in series for treating the same water at a rate of 0.5 ML/d. Practical considerations limit the diameter of the columns to 3m. Calculate the minimum required height of the columns.

Consider particles in suspension and their settling behaviour at different concentrations select the correct statement(s). Type 1 settling is called discrete settling. Your option is Correct B Terminal velocity in suspension is achieved when drag force is balanced by gravity force. Your answer is IN-CORRECT Correct Option 24 In Type 1 settling, for Ree(100, 300) Cn = Re 3 +0.34 (Re = Reynold's number) VRe D In Type 2 settling, the velocity of floc does not remain terminal and keeps changing as the size of the floc changes.
