In order to improve the performance of methane production from agro-waste, a batched four-stage–two-phase anaerobic digestion (4S2P-AD) system was designed combine advantages both co-digestion (co-AD) and two-phase AD. The initial separation two phases performed using rice straw (RS) as feedstock in acidogenic phase cow manure (CM) methanogenic at low inoculum/substrate (I/S) ratios 0.5 0.2 hig...

Influences of following anaerobic digestion (AD) parameters like microaeration, pH, and VSS (Volatile Suspended Solid) using sour cabbage as substrate was checked in the publication. Results fermentation under condition small oxygen addition presented this research can be classified dark (DF—a special case AD) or hydrogenotrophic digestion. The investigations were carried out for two concentrat...

Poultry waste is rich in organic matter, which allows its treatment by the process of anaerobic digestion (AD) to reinforce economic and environmental green strategies. The aim this study assess technical feasibility poultry AD semi-continuous mode intensify methane production co-digestion with physico-chemical sludge, i.e., product primary wastewater after slaughtering process. First, dropping...

key dissimilarities between thermophilic and mesophilic anaerobic digestion of waste activated sludge (was) were experimentally studied in this research. typical was with total solids (ts) concentrations of 30 and 60 g/l were digested anaerobically in a batch digester at mesophilic and thermophilic temperatures. solids reduction, total cod changes, the production of different volatile fatty ...

This study analyses anaerobic digestion (AD) as a renewable energy technology by quantifying the emissions avoided and the cost incurred in the process. The quantitative model developed and demonstrated uses basic farm information to evaluate dairy farms from an environmental and economic perspective. Based on the cost of installing and operating an anaerobic digester and the emissions avoided ...

Antibiotics are widely used in human and veterinary medicine, they accumulated various types of waste, including sewage sludge (SS) cattle slurry (CS), processed by anaerobic digestion (AD). Anaerobic treatment is a method enabling the stabilization these substrates before transferring to environment. The presence contaminants, such as antimicrobials, organic AD not regulated law. accumulation ...

The processes of anaerobic digestion and co-digestion are complicated and the development of computational models that are capable of simulation and prediction of anaerobic digester performances can assist in the operation of the anaerobic digestion processes and the optimization for methane production. The artificial neural network approach is considered to be an appropriate and uncomplicated ...

Anaerobic Digestion (AD) is one of the most widely used methods in field sustainable bioenergy production from various feedstock. One such feedstock algae waste which has become an increasingly serious environmental problem. AD algal biomass hindered by presence resistant cell walls; hence a pretreatment step usually required to decompose wall structure. This study uses green (Enteromorpha) and...

Anaerobic digestion (AD) is a biological process where different trophic groups of microorganisms break down biodegradable organic materials in the absence of oxygen. A wide range of AD technologies is being used to convert livestock manure, municipal and industrial wastewaters, and solid organic wastes into biogas. AD gains importance not only because of its relevance in waste treatment but al...

Swine manure mono-digestion results in relatively low methane productivity due to the degradation rate of its solid fraction (manure fibers), and high ammonia water content. The aqueous soaking (AAS) pretreatment fibers has been proposed for overcoming these limitations. In this study, continuous anaerobic digestion (AD) mixed with optimally AAS-treated was compared AD untreated fibers. Due lab...
