Dear all,

The book on Practical Handbook on FSM by AIT/ ADB has some useful information. However, the book needs to include some important information to make it practical. It mentions biogas generation from FSM as one of the options. However, it does not mention rate of biogas production from FSM. It is expected to be very low as FSM contains mostly completely degraded/ semi degraded human wastes. Design criteria for Sand filter bed is not mentioned. Rate of filtration through sand filter is required for designing the filter bed. There is no mention of any process to make sludge pathogen free for its safe reuse for agriculture purpose. All these points need to be discussed before designing any option.

With regards
Pawan

You will find very interesting research findings on sanitation and its impact at different level at this site squatreport.in/

This is another link wastewaterinfo.asia/ that ADB has created in Sanitation.
