A 100-mL water sample is collected from the activated sludge
process of municipal wastewater treatment. The sample is placed in
a drying dish (weight = 0.5000 g before the sample is added), and
then placed in an oven at 104°C until all the moisture is
evaporated. The weight of the dried dish is recorded as 0.5625 g. A
similar 100-mL sample is filtered and the 100-mL liquid sample that
passes through the filter is collected and placed in another drying...

A wastewater treatment plant with activated-sludge process
treats wastewater for 120,000 m3/d. The effluent standard for both
BOD and TSS is 20 mg/L. Influent TSS concentration is 450 mg/L and
influent BOD concentration is 220 mg/L. MLSS concentration is 3500
mg/L (Assume no nitrification and temperature is 20°C). Determine:
(20 pts) (a) Influent BOD and TSS concentration to the aeration
tank if the treatment efficiencies in primary clarifier are 30% and
70% for BOD and TSS, respectively. (b) Determine sludge...

A conventional activated-sludge plant treats 10.0 MGD of
municipal wastewater with a BOD concentration of 240 mg/l and
suspended solids of 200 mg/l. The sludge flow pattern is shown in
Figure 11-1 of the textbook with a gravity belt thickener to
concentrate the excess activated sludge. Primary and thickened
activated sludge are pumped separately to the anaerobic digester.
The primary clarifier removes 50% of the suspended solids and 35%
of the BOD. The primary sludge solids content is 4.0%. The...

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...

Describe what happens to the wastewater from our homes,and give
information about the wastewater treatment plants ( preferred if
you mentioned Abu Dhabi - UAE ). What they are, what area they
serve, what is the capacity, what level of treatment they provide,
what do they do with the cleaned output, etc.
the study should conclude with a tangible plan for wastewater
management from a specific location such as school, a town, a farm,
a mall and so on.

Determine the daily primary sludge production during the
following wastewater treatment with these operating
characteristics:
Flow = 5000 gpm (gallons per minute)
Influent SS = 180 mg/L
Removal efficiency = 60%
Volatile solids = 70% of SS
Specific Gravity of volatile solids = 0.967
Fixed solids = 30% of SS
Specific Gravity of fixed solids = 2.4
Sludge solids content = 5.00%

About wastewater treatment:
A. Explain the primary, secondary and tertiary WWTPs
(Wastewater Treatment Plants). You can use diagrams and explain
them.
b. In addition to the WWTPs, mention and explain two
alternatives for treating wastewater.
