Question Paper

Differentiate between aerobic and anaerobic processes of decomposition of organic matter.

Draw neat sketches of the following:

Floor Trap

Intercepting Trap

Differentiate between 'Storm sewage', 'Sanitary sewage', 'Domestic sewage' and 'Industrial sewage'.

Determine the size of a circular sewer for a discharge of 600 l/s running half full. Assume i =0·0001 and n =0.015. For half full sewer, q/Q =0.5.

Draw a neat sketch of a drop manhole and indicate where is it used.

Describe in order various stages followed in the construction of sewers.

If the 2-day 25°C B.O.D. of a sample of sewage is 200 what will be its 5-day 30°C B.O.D.

K25 0.1256, K30 0.1578,
La, T La, 20(0.02 T
T is the temperature.

The average sewage flow from a city is 80 x 10^6 lid. If the average 5-day B.O.D. is 285 compute the total daily 5-day oxygen demand in kg and the population equivalent of the sewage. Assume per capita B.O.D. of sewage per day 75 g.

Explain the self-purification of streams.

Explain and sketch a grit chamber.

Explain the theory of activated sludge process and illustrate the sequence of operations by drawing a flow diagram.

What do you mean by 'digestion of sludge' How is it carried out at municipal sewage treatment plants

7. Write short notes on any four of the following:

Oxygen sag curve

Waste water reuse

Catch basins

Oxidation pond

Screens

Composting
