WebSome researchers have reported that they have been able to reduce the hydraulic retention time (HRT) from a necessary 15 to 20 days in mesophilic digestion down to as little as 3 days at a thermophilic temperature in the region of (55°C) with stable fermentation and methanogenic activity. Web17 nov. 2024 · In brief, anaerobic digestion of biodegradable residues consists of four metabolic stages, as shown in Figure 1. During hydrolysis, bulk biomass is degraded to soluble carbohydrates, proteins and lipids followed by acidogenesis, where these are converted mainly to short-chain carboxylic acids (SCCA) and alcohols.
