Waste Water Engineering

Q1: Pick up the incorrect statement from the following :

A Septic tanks are horizontal continuous flow type of sedimentation tanks

B Septic tanks are generally provided a detention period of 12 to 36 hours

C Septic tanks are completely covered and high vent shafts are provided for the escape of foul gases

D Septic tanks are generally classified as tanks which work on the principle of anaerobic decomposition

E None of these.

ANS:E - None of these.

The incorrect statement from the options provided is: Septic tanks are horizontal continuous flow type of sedimentation tanks. Septic tanks are not horizontal continuous flow type sedimentation tanks. Instead, they are typically designed as vertical, closed tanks where sewage undergoes settling and partial treatment through anaerobic decomposition. The design of septic tanks allows for the separation of solids from liquids and the digestion of organic matter by anaerobic bacteria. Therefore, the correct option is: Septic tanks are horizontal continuous flow type of sedimentation tanks.
