Your task is to build a wastewater treatment plant to handle all
of the domestic wastewater produced by a housing estate. Using
population equivalent, PE = 65000, design, describe and calculate
briefly the sizes of all the unit processes in the treatment plant
that are going to be built. You may assume the value that is not
given.

A wastewater treatment plant that treats wastewater to secondary
treatment standards uses a primary sedimentation process followed
by an activated sludge process composed of aeration tanks and a
secondary clarifiers.
This problem focuses on the activated sludge process.
The activated sludge process receives a flow of 15 million
gallons per day (MGD).
The primary sedimentation process effluent has a BOD5 concentration
of 180 mgBOD5/L (this concentration is often referred as S). Before
flowing into the activated sludge process, the primary...

A municipal wastewater treatment plant discharges 20,000 m3/d of
treated wastewater to a stream. The wastewater has a BOD5 of 30
mg/L with a k1 of 0.23 d-1. The temperature of the wastewater is 20
oC, and the dissolved oxygen is 2.0 mg/L. The stream just above the
point of wastewater discharge flows at 0.65 m3/s, has a BOD5 of 5.0
mg/L, and is 90% saturated with oxygen. The temperature of the
stream is also 20 oC. After mixing, the...

Q8. As an Engineer, you are requested to implement a small
wastewater treatment plant for your apartment that comprise of 52
flats. Explain the different steps or stages involved in the
wastewater treatment process.

A municipal wastewater treatment plant is designed for COD
removal and nitrification. The wastewater characteristics and
kinetic coefficients are described in the table below. The aeration
tank DO concentration is 2.0 mg/L and MLSS concentration is 2500
mg/L. The temperature is 15C. Assume that the concentration of
influent NH4-N that is nitrified accounts for 80% of influent TKN.
Calculate the following parameters as a function of SRT (i.e.,
derive mathematical expressions of the following parameters as a
function of SRT,...

. The average flow of wastewater into the Metropolitan
Wastewater Treatment Plant is 180 MGD. What is the loading of total
solids in this wastewater (lbs/day)? What is the loading of
volatile solids in this wastewater (lbs/day)?

A new wastewater treatment plant was built to treat the
wastewater flow 800,000 gpd. The capital cost to build the
wastewater treatment plant was $6,000,000. The annual operation and
maintenance costs of operating the plant is $700,000/year. Estimate
the cost of treating 1000 gallons of wastewater ($/1000 gallon).
Assume the design life as 20 years and interest rate of 4%.

The total flow at a wastewater treatment plant is 682 m3/day.
The purpose of the plant is to remove compound Z from the
wastewater by treating it in reactors, using a newly developed
microbial process. Assume the microbial treatment can be modeled as
a first order reaction with a rate coefficient of 0.36/h. Suppose
the flow is split evenly and treated in two parallel reactors– one
complete mix and one plug flow -- each with a volume of 88 x...
