Anaerobic Digestion • Byproducts: (raw substrates will affect) Digester gas- methane can be as high as 70% more commonly 60%; carbon dioxide at 30% (40%) with trace elements of hydrogen sulfide, water vapor, etc. Post digested material (usually a 50% solids reduction within digester); then
Sep 20, 2018· Cons of anaerobic digesters. Here are some of the disadvantages to anaerobic digesters. Expensive; Installation costs of the anaerobic digesters can be prohibitive since it requires some massive financing to set it up. The operating expenses and the maintenance cost are also costly which makes it difficult for farmers to acquire.
Nov 02, 2017· Anaerobic digestion is a sustainable approach to treating organic wastes: • produces renewable energy • produces a product that recycles organics and nutrients • can be used to meet EPA requirements for biosolids • stable operations require regular monitoring and good
