In order to understand the correlation between ammonia and methanogenesis metabolism, methane production pathways and their specific rates were studied at total ammonium nitrogen (TAN) concentrations of 0.14–9 g/L in three methanogenic sludges fed with acetate, at both mesophilic and thermophilic conditions. Results showed that high levels of TAN had significant inhibition on methanogenesis; ...

The inhibitory effect of azo dyes and quinoid compounds on an anaerobic consortium was evaluated during a decolorization process and biogas production. In addition, the impact of quinoid compounds such as lawsone (LAW) and anthraquinone-2,6-disulfonate (AQDS) on the rate of decolorization of Direct Blue 71 (DB71) was assessed. The anaerobic consortium was not completely inhibited under all ...

Membrane gas permeation using glassy membranes proved to be a suitable method for biogas upgrading and natural gas substitute production on account of low energy consumption and high compactness. Glassy membranes are very effective in the separation of bulk carbon dioxide and water from a methane-containing stream. However, the content of hydrogen sulfide can be lowered only partially. This ...

Biogas is a natural gas also known as biofuel or biomass and is produced by breaking down organic material such as household waste, manure and crops grown specifically for biofuel with temperature-sensitive microbes and capturing the by-products. In practice, it is difficult to find a pumping system for this application. Why? The pumps needs to handle fluid media as well as gas parts The ...

Abstract DMT has developed a process for biological desulfurization at low pH for the treatment of biogas. This process (BioSulfurex®) is pH, temperature, nutrient and oxygen controlled. During an intensive research period the elimination capacity (EC) and removal efficiencies (RE) at different process conditions were determined. The effect of variations in H2S loading, cleaning procedures ...

INTRODUCTION As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is ...

Biochemical methane potential assays (BMP assays) were performed to study the potential of anaerobic treatment of in-mill wastewaters. The assay results indicated that condensate and the BCTMP effluent, which are currently treated with the anaerobic internal circulation reactors, were the best streams for anaerobic treatment because of their relatively high degradability (>80%) and initial rates ...

Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill, and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector. According to the International ...

Biogas production has evolved from a niche practice into a pivotal part of renewable energy, converting organic waste into a clean energy source. Wastewater treatment plants, food waste facilities, and landfill gas recovery systems utilise anaerobic digesters to break down organic matter. This digestion process produces biogas—a mixture of methane and carbon dioxide. Capturing this energy, ...

Chesterfield BioGas (CBG) supplied the UK’s first biogas upgrading plant to produce clean biomethane for direct injection into the national gas grid for use by all consumers. The project was successfully completed and gas injected into the national grid at the wastewater treatment site of Thames Water site at Didcot, Oxfordshire in October 2010. This achievement was a benchmark moment for ...

How can the EU bioeconomy best contribute to the transition towards sustainable development and a climate-neutral economy by 2050? In April 2021, the European Commission published a report[1] presenting four scenarios for the future EU bioeconomy until 2050. One of the scenarios presented in the report is particularly encouraging for our sector as it forecasts a growth of the bio-based industry, ...
