The upper chamber is called the sedimentation chamber or flowing through chamber, through which the sewage flows at a very low velocity and the lower chamber is the digestion chamber, in which the sludge gets digested due to anaerobic decomposition.

Working Condition in Imhoff Tanks
Imhoff tanks are used for the treatment of sewage. The working condition in Imhoff tanks is as follows:
Anaerobic in Lower Compartment
The lower compartment of the Imhoff tank is designed for anaerobic treatment of sewage. Anaerobic bacteria decompose organic matter in the absence of oxygen.
Aerobic in Upper Compartment
The upper compartment of the Imhoff tank is designed for aerobic treatment of sewage. Aerobic bacteria use oxygen to break down organic matter.
Working Principle
The working principle of Imhoff tanks is based on the following steps:
1. Settling
The first step in the treatment process is settling. The sewage is allowed to settle in the tank for a period of time. The heavier solids settle to the bottom of the tank and the lighter solids float to the top.
2. Anaerobic Treatment
The settled solids are then moved to the lower compartment of the tank where anaerobic bacteria decompose organic matter.
3. Aerobic Treatment
The liquid from the lower compartment is then moved to the upper compartment of the tank where aerobic bacteria break down any remaining organic matter.
4. Clarification
The final step in the treatment process is clarification. The liquid is allowed to settle in the tank and any remaining solids are removed.
Conclusion
In conclusion, Imhoff tanks are designed for the treatment of sewage. The tanks have a lower compartment for anaerobic treatment and an upper compartment for aerobic treatment. The working principle of Imhoff tanks is based on settling, anaerobic treatment, aerobic treatment, and clarification.
