A perfectly mixed aeration pond with no recycle (return line) serves as the biological reactor for a small community. The pond receives 30 cubic meters/day of influent with a BOD5 of 350 mg/L that must be reduced to 20 mg/L before discharge. It has been found that the kinetic constants for the system are Ks=100mg/L, BOD5 kd=0.10 d^(-1),fm=1.6 d^(-1), and Y is 0.60 mg VS/mg BOD5.
(a) What must the hydraulic detention time be in the aeration pond?
(b) What mass of microbes will be produced in the pond each day?
Important information about Mechanical engineering dynamics, A 3000 lb car rests on a horizontal street out of gas with its brakes locked.
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..

how many cubic feet of seawater, density 60 lb/ft^3, must be processed to recover 1 ton of magnesium, 1,272 ppm?
The cylinder B is released from rest. Determine the speed of both masses (vA and vB) after B moves by h m. Also calculate the angular displacement for the pulley D. The diameter of the pulley D is 0.2 m. Neglect all friction.
Discuss the dangers of optimization in terms of minimum section to support loads. In other words, how would optimizing for bending stresses affect the shear capacity of a section
A vertical triangular orifice in the wall of a reservoir has a base 0.9m long,0.6m below its vertex and 1.2 m below the water surface. determine the theoretical discharge?
A more conservative increase from 27.5 mpg in 2011 to 35 mpg by 2020 is supported widely in Washington. California and 13 other states + the District of Columbia hope to increase that stander to 35 mpg by 2017 and 40 mpg by 2020.
The tank is insulated on the outside and the partition between the two sections is also an insulator. The partition can withstand a pressure differential across it of 400 kPa, before rupturing.
Suppose that a person who boards the elevator on the ground floor gets off on the fifth floor. Assuming that the elevator has achieved operating speed by the time it reaches the second floor and that it is still moving at its operating speed as it..
Calculate the fraction of total atrazine that will be adsorbed to the soil given that the soil has an organic carbon content of 2.5%. The bulk density of the soil is 1.25 g/cm3; this means that each cubic centimeter of soil (soil plus water) conta..
The average P concentration in the runoff if the overall (agricultural and residential areas) runoff coefficient = 0.4, 40% of P is removed from the agricultural area by rainfall, and 90% of P is removed from the residential area by rainfall.
