Bacteria like saprophytic organisms are present that react on complex organic matter and decomposed. During digestion, various microbes use the organic matter such as animal manure, sewage sludge, wasted food and other organics in the absence of oxygen. Anaerobic digestion is widely used as a source of renewable energy. • Anaerobic digestion is particularly appropriate for wet wastes, while composting is often appropriate for drier feedstocks. Shana, A., et al. In anaerobic digestion, organic pollutants are converted by anaerobic micro-organisms to a gaseous product (including methane gas) that has the potential for reuse. Two common types of suspended media digesters are the upflow anaerobic sludge blanket digester, or UASB digester (Figure 10), and the induced blanket reactor, or IBR digester (Figures 11 and 12). This process can be very useful to treat arising organic waste such as: - sewage sludge - organic farm wastes - … - Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. ⇛ The sludge digestion tanks are generally circular in shape with a flat or hopper-shaped bottom. Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. from trickling filters, activated sludge) and anaerobic sludge also dries better and results in less odour as it is more stabilised. They are all artistically enhanced with visually stunning color, shadow and lighting effects. The microbial activity was characterized by 16S RNA sequencing. During digestion, the organic and odorous fraction of the sludge is stabilized by microorganisms that degrade the volatile organic fraction of the sludge in the presence or absence of oxygen.
