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 […]

How to Solve Food Waste AD Pipe Blockage Problems

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 […]

What is thermal Hydrolysis? as used in AD Plants

What is Thermal Hydrolysis?

So you want to know, what is the thermal hydrolysis process? 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 chemical bonds holding together large tissue molecules […]

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, […]
