A completely mixed activated-sludge process is being designed for a wastewater flow of 10,000 m3/d (2.64 mgd) using the kinetics

equations. The influent BOD5 of 180 mg/l is essentially all soluble, and the design effluent BOD5 is 20 mg/L. The effluent biosolids concentration is 15 mg/l, of which 80% is volatile and 65% is biodegradable. For sizing the aeration tank, the SRT is selected to be 8 d and the MLVSS 3000 mg/L. The kinetic constants are as follows:
Y=0.6 mg VSS/mg BOD, ka = 0.06 d-1, Ks = 60 mg/L of BOD, and k = 5.0 day-1.
Determine the efficiency of soluble BOD removal, using the formula
E=S0-Se/S0 X 100
Here, S0 is influent soluble BOD concentration and Se is influent soluble BOD concentration.

Answer:

The efficiency of soluble BOD removal is 88.8889%

Explanation:

For this question not all the given parameters will be used, only the following:

BODi = influent soluble concentration = 180 mg/L

BODe = effluent soluble concentration = 20 mg/L

Question: Determine the efficiency of soluble BOD removal, η = ?

The efficiency of soluble BOD removal can be calculated using the following formula:

\eta =\frac{BOD_{i}-BOD_{e}}{BOD_{i} } *100=\frac{180-20}{180} *100=88.8889%

irakobra [83]

Answer:

Option D, Ground Wire

Explanation:

Oleg is a mustimeter or multi tester or a basic voltage tester which is used to test the ground. The main purpose of the tester is to ensure that the outlet is connected to the ground of the circuit, thereby ensuring its proper functioning.

Hence, option D is correct
