Question Paper
1. Describe the Activated Sludge Process (ASP). What are the limitations of the ASP Explain various modifications of the ASP.
What are the main principles of design of oxidation ponds? Explain briefly.
What measures are required to prevent sewage sickness? Describe them briefly.
Explain various methods of testing of sewers.
Explain the process of Anaerobic Sludge Digestion.
What are the various zones of pollution developed in the river system after a polluted stream is added to the river?
10 million litres per day of sewage of a town, with a BOD5 of 220 is to be discharged into a river stream having flow of 250 l/s and BOD5 of 5 mg/l. What should be the percentage treatment of the sewage required, if the BOD5 of the river cannot exceed 15 mg/l Assume that the sewage and river are at the same temperature.
Calculate the quantity of sludge produced per day in a clarifier having moisture content of 95%. The clarifier removes 60% of incoming solids. Inflow to the clarifier is 200 m^3/hr with 300 ppm of suspended solids. Assume specific gravity of sludge as 1·02.
Differentiate between hydraulic retention time and sludge retention time.
Describe briefly about various physical and chemical processes affecting the natural purification of rivers.
Differentiate between single-stage standard digester and two-stage high rate digester.
Describe various methods of sludge drying.
Explain DO sag curve.
