Let’s not be too embarrassed. We all do it. When we go to the toilet we can make a bit of a smell. If your home is not connected to mains drainage then your toilet smell can stay with you in your septic or storage tank. |
The BOD factor is a measure of the Biochemical Oxygen Demand – oxygen consumed by bacteria as it breaks down the pollution content of sewage. Raw sewage straight from the toilet has a high pollution content and a high |
demand for oxygen (BOD factor of 300 or more). As oxygen assists in breaking down the pollution content the BOD factor is reduced. The lower the BOD factor, the lower is the pollution hazard and smell. |
