Biogas Plant Substrate Mixing During Fermentation Creates a Stir with AD Plant Operators

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 […]

What is thermal Hydrolysis? as used in AD Plants

What is Thermal Hydrolysis? Thermal Hydrolysis Technology Explained

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 […]

Improving Biogas Plant Efficiency – Why Ferrous Chloride Not Ferric Chloride is Best

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, […]

Dairy Farmers Consider Selling Herds and Going for Biogas Production

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 […]

Pipeline Quality Gas from Anaerobic Digestion Goes Ahead in Québec

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 […]
