Question Paper
Briefly describe the principle of Gas Transfer and its applications in waste water treatment.
With the help of neat sketches, briefly describe dissolved air flotation process.
How would you estimate the quantity of storm sewage from an area?
Find the relation between the side of a square section of one sewer and the diameter of a circular section of another sewer when both are hydraulically equivalent.
What are manholes? Explain with the help of a diagram.
When is pumping of sewage required to be done Draw a sketch of a typical sewage pumping station.
The B.O.D. of a sewage incubated for one day at 30°C has been found to be 120 mg/l.What will be its 5-day 20°C B.O.D., if the values of the reaction constant k are 0.1 and 0.16 at 20°C and 30°C respectively? La,30 La, 20 [(0.02 0·6], T is temperature.
Explain the following:
B.O.D.
C.O.D.
A sewage outfall is serving a part of a city having a population of 50,000. The quantity of sewage is 136 1pcd and its 5-day 30°C B.O.D. is 300 ppm. The sewage is to be disposed off by dilution in a river having a flow of 2'83 m^3/sec in summer season. The minimum dissolved oxygen (after mixing) in stream cannot be lower than 3 ppm and its average temperature in summer is 30°C. Find out whether treatment is necessary to be given (i.e., primary or secondary
Draw a sketch of a trickling filter and describe its working.
What is sludge thickening? Explain any one method.
Write a note on thermal reduction of sludge.
7. Write short notes on any four of the following:
Sludge Dewatering
Anaerobic Digester
Step Aeration
Grit Chamber
Waste Water Reuse
Inverted Siphon
