Bio digesters are designed for the accelerated decomposition of solid wastes from animal feed operations, municipal solid waste, and industrial by products and waste water processing operations.
Anaerobic digestion is the most commonly used method of wastewater sludge treatment, where the primary aim is to break down the sludge in order to minimize the volume that is left for disposal. During this process the organic matter is decomposed by anaerobic bacteria in an oxygen-free environment, producing carbon dioxide and methane gases and […]
One of the benefits of using livestock waste in the biogas production process is that, compared to waste used in municipal sewage digesters, it has a relatively uniform composition. Consequently, upsets are uncommon once the digestion process is underway and has stabilized. If the digestion process is correctly managed, things are likely to run smoothly […]
Biogas Collection: Collecting the Biogas As mentioned in the previous article, digester gas is typically comprised of 60-70% methane, with the balance consisting primarily of carbon dioxide together with smaller amounts of hydrogen sulfide and other trace gases. To prevent the biogas from being contaminated by atmospheric oxygen water levels need to be maintained so […]
Digester Design One of the most critical elements of digester design, and the first thing to consider when planning to install a biogester, is your size requirements. The amount of waste that will be digested, and whether or not this will need to be diluted, will determine the size of the digester needed. The amount […]
