Anaerobic digestion (AD) processes can face operational challenges or flaws such as substrate structure and characteristics complexity, process low productivity, inefficient biodegradability, poor stability, which suppresses reduces biogas biomethane production. As a result of the need to overcome these challenges/shortcomings improve enhance yield, intensification methods have gained attention...

This work analysed the effects of Biochar (BC) addition to Anaerobic digestion (AD) wastewater Mixed sludge (MS) in semi-continuous mode. A 3 L digester was operated at 37 °C for 100 days, feeding MS collected every three weeks same treatment plant, and 10 g L−1 BC. The average performance (biogas 188 NmL d−1, 68% methane) improved presence BC 244 69% methane). According results multiple linear...

This study aimed to assess the potential environmental benefits of implementing low-cost digesters valorize agro-industrial waste in non-centrifugal cane sugar (NCS) sector. Two scenarios were considered: i) current scenario which organic and wastewater burned outdoor discharged into a water body, respectively; ii) anaerobic digestion (AD) scenario, biodigesters used for treatment on-site. Resu...

Biomass pretreatment is a critical method for improving the anaerobic digestion (AD) performance of lignocellulosic feedstocks. In this study, an effective combined ammonia–autoclave was selected corn straw at 90 °C using four ammonia concentrations (7%, 9%, 11%, and 13%). The results showed that improved substrate’s degradation efficiency system’s buffer capacity, significantly hydrolysis biog...

in the present study, the increase of organic loading rate (olr) influences the biomethanisation of sewage sludge. the research was conducted at technical scale in wastewater treatment plant in tyrowo (near ostróda, poland). it has been shown that the increase of olr, by adding co-substrates, cause the increase of biogas production but not biogas yield coefficient. the substrates used for anaer...

A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...

introduction: the need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. on the basis of environmental and economic considerations, these materials require treatment and management. anaerobic digestion and creation of biogas are the most effective methods of waste management. several parameters affect the anaerobic digestion of ...

Challenges are always proposed when pursuing more energy and resource recovery from waste activated sludge via the anaerobic digestion (AD) process. Recently, microbial electrolysis has been integrated with AD proven to enhance conversion system stability. This study investigated effect of organic load on fermentation biogas production in a bioelectrolysis-assisted reactor. Four different loads...

Anaerobic biological treatment can comprise a viable route of CH4 production through the energy recovery organic solid waste (OSW). This work therefore presented bibliometric analysis research trends on theme "Applicability via Digestion in Organic Solid Waste", considering experimental articles published from 2018 to 2022 Web Science database™; used VoSviewer software define trends, and found ...

As the amount of sewage sludge (SS) is increasing worldwide, anaerobic digesters (ADP) are being distributed to reduce it and treat in an environmentally friendly way. In Korea, 20 years have passed since introduction ADP, but number treatment plants (STP) installed with ADP only about 10% total STP. Accordingly, problems improvements were examined through material flow analysis targeting STP, ...
