Wastewater treatment is to be designed for a newly developed area located within the vicinity of forest reserve park and commercial space (shopping mall). Given that the current population are 20,000. You are to design a wastewater treatment plant for only biological process units of Trickling filter which can serve the purpose of both BOD removal and nitrification. You are to submit a design report containing :
1. Growth area and population trends for a design period of 20 years (Use arithmetic method).

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,...

There are two coal-fired power plants located in the vicinity of
a major metropolitan area. These power plants emit sulphur dioxide,
which causes respiratory issues for the metro population as well as
resulting in acidic rainfall. The EPA has determined
that the amount of sulphur dioxide emitted needs to be reduced by
180 tons. The marginal abatement cost function for the first power
plant is given by MC(x) = 5x and the marginal abatement cost
function for the second power plant...

There are two coal-fired power plants located in the vicinity of
a major metropolitan area. These power plants emit sulphur dioxide,
which causes respiratory issues for the metro population as well as
resulting in acidic rainfall. The EPA has determined that the
amount of sulphur dioxide emitted needs to be reduced by 169 tons.
The marginal abatement cost function for the first power plant is

A researcher interested in the treatment of depression developed
an intensive treatment program designed to teach people to think
positively. The researcher began the study by recruiting 50 college
students who received extremely low scores on a well-validated
measure of self-esteem. Each of the 50 participants agreed to
attend four 1-hour therapy sessions per week for two weeks (for a
total of eight sessions). Thirty-seven of the 50 original
participants remained in the study and completed all eight
sessions. At...

An anaerobic stabilization pond is designed for a residential
area have a population of 8000 (wastewater production is 225
L/day-capita). Pond is designed as a facultative pond and
maturation pond in series. The BOD of raw sewage is 180 mg/L, the
influent FC is 106 FC/100 mL and the operating temperature is 12°C.
The effluent BOD concentration should be lower than 20 mg/L. Design
completely both ponds using the relevant information and
assumptions to provide an efficient design.

Design an aeration tank for activated sludge wastewater
treatment designed to meet an effluent standard of 10 mg/L
BOD5. The flow from the primary effluent is 10
m3/min with a primary effluent BOD5 of 250
mg/L. The design calls for the suspended solids to equal 3500 mg/L
for an SRT of 5 days. The decay rate constant is 0.03
day-1 and the yield is 0.75 mg/mg. Determine:
the tank volume required to meet these specifications,
the resulting mass of sludge...

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 tire company has developed a new tread design and claim that
the newly designed tire has a mean life of 60,000 miles or
more.
To examine the claim, a random sample of 16 prototype tires is
tested. The mean tire life for this sample is 60,758 miles.
Assume that the tire life is normally distributed with unknown
mean µ and standard deviation σ=1500 miles.
(a) Please construct a 90% confidence interval for the mean life
of the new designed...
