The importance of “creating a stir” in the fermentation tanks of fully mixed bio-reactors for better biogas yields, and improved process stability, is becoming better understood by many AD plant clients around the globe, as more Anaerobic Digestion Plants are being built and the biogas industry matures. A scan of world news on this subject revealed that […]
The following article is an explanation of the options for Anaerobic Digestion Plant Digestate Enhancement, (Fibrous Biogas Digestate), which were reviewed by Pell Frischmann Consultants when they produced a report for WRAP in the UK, on the subject of Biogas Digestate Enhancement and Treatment Techniques, in 2012. It includes an updated background to the use of […]
At the RWM Exhibition at the NEC Birmingham, UK, last week, while I was talking to Anaerobic Digestion service providers, a recurring topic which came up was the significant number of UK biogas plants which have recently been afflicted by pipe blockages. These were in many cases proving to result in long plant outages, and […]
So you want to know; “What is the thermal hydrolysis process?” – and to understand basic thermal hydrolysis technology. Thermal Hydrolysis is a chemical process in which the organic molecules (in the substrate/ feed material) are split into two parts by the addition of a molecule of water. The process forces the water molecules between the […]
Low Temperature Anaerobic Digestion – The Third Type Of AD Process I was intrigued to see a newcomer with a stand at the AD & Biogas Association Exhibition and Conference 2014 last month at the NEC Birmingham. NVP Energy was there to present their unique and innovative low temperature (< 20°C) Anaerobic Digestion (Lt-AD) wastewater (WW) treatment technology […]
When seeking to improve biogas plant efficiency understanding why Ferrous Chloride Not Ferric Chloride is Best an be important. At the start of my recent enquiry, the expert from Lukeneder helped by explaining the differences between Ferrous Choride and Ferric Chloride. I think that my reaction of confusion, as I looked at the Lukeneder brochure just before that, […]
In a very welcome move, the White House is backing farm biogas production from manure and other feedstocks, as a way to reduce national methane emissions which are implicated as a significant source of climate change. The US dairy industry not only came to the same conclusion in 2009, but has been working toward its […]
Here we go again mashing together two news articles which we have found interesting, in order to bring our readers straight to the point regarding an (until now) little appreciated advantage of owning a biogas plant. It is all about investment in an anaerobic digestion plant helping diversify and through that, to stabilize the financial […]
The acceptance of biogas upgrading to Pipeline Quality Gas (natural gas pipeline quality) is rising, although in many locations the natural gas network owners remain skeptical about the consistency of the gas quality achievable from current upgrading technology. As the article excerpt below shows, Québec’s municipal wastewater sludge Anaerobic Digestion Plant will be another producer […]
