The article discusses the technical foundations and practical methods of processing organic waste in a biogas plant, as a result of which biogas is obtained, the effect of biomass moisture on the output of biogas is studied. The principles of quality management of natural and man-made energy resources are outlined, in order to increase the efficiency of the technology of anaerobic processing of biogas production, considering the concentration of methane, due to continuous and remote measurement of the effect of humidity of the base raw materials at the output from biogas. The article analyzes the method and recommends the use of devices for monitoring and regulating biomass moisture indicators.

“…Methanogenesis, acidogenesis, hydrolysis, and acetogenesis are the four main processes involved in anaerobic digestion. The parameters influencing the anaerobic digestion process include temperature, pH, total solids, retention time, volatile solids, etc ( Cremonez et al, 2021). There are vast benefits of anaerobic digestion for the valorization of agricultural waste such as being cost-effective, simple, and no power requirement.…”

“…AD in multiple stages, where the control of operating variables in each stage is facilitated, is a viable process leading thus to optimized environmental/experimental conditions for the overall process. Consequently, increased yields not only of solids removal but also of methane productivity can thus be achieved, while a higher total energy yield arises also through hydrogen generation [15]. The success of AD operation depends primarily on the type of digestion system (single-or two-stage), but also on several factors (such as pH, temperature, and nutrients), and operating parameters (like hydraulic retention time (HRT) and organic loading rate (OLR)) [16].…”

“…The two-stage treatment process is more advantageous in comparison to the single-stage system for the treatment of the wastewaters containing a considerable fraction of recalcitrant organics such as LCM and CW. Despite the advantages of two-stage digestion systems reported in the literature [15], limited research is accessible in terms of the single-and two-stage digestion process performance comparison [25].…”

Assessment of Single- vs. Two-Stage Process for the Anaerobic Digestion of Liquid Cow Manure and Cheese Whey

et al. 2021

The growing interest in processes that involve biomass conversion to renewable energy, such as anaerobic digestion, has stimulated research in this field in order to assess the optimum conditions for biogas production from abundant feedstocks, like agro-industrial wastes. Anaerobic digestion is an attractive process for the decomposition of organic wastes via a complex microbial consortium and subsequent conversion of metabolic intermediates to hydrogen and methane. The present study focused on the exploitation of liquid cow manure (LCM) and cheese whey (CW) as noneasily and easily biodegradable sources, respectively, using continuous stirred-tank reactors for biogas production, and a comparison was presented between single- and two-stage anaerobic digestion systems. No significant differences were found concerning LCM treatment, in a two-stage system compared to a single one, concluding that LCM can be treated by implementing a single-stage process, as a recalcitrant substrate, with the greatest methane production rate of 0.67 L CH4/(LR·d) at an HRT of 16 d. On the other hand, using the easily biodegradable CW as a monosubstrate, the two-stage process was considered a better treatment system compared to a single one. During the single-stage process, operational problems were observed due to the limited buffering capacity of CW. However, the two-stage anaerobic digestion of CW produced a stable methane production rate of 0.68 L CH4/(LR·d) or 13.7 L CH4/Lfeed, while the total COD was removed by 76%.
