Technology Review of Biogas Sanitation (Draft) - Biogas Sanitation for Blackwater, Brown Water or for Excreta and Organic Household Waste Treatment and Reuse in Developing Countries

It is also an excellent technology for organic sludge treatment, collected from septic tanks, holding tanks, dry toilets, settlers or from aerobic wastewater treatment systems.
