Evaluation of anaerobic digestion processes for short sludge-age waste activated sludge combined with anammox treatment of digestate liquor
The need to reduce energy input and enhance energy recovery from wastewater is driving renewed interest in high-rate activated sludge treatment (i.e. short hydraulic and solids retention times (HRT and SRT, respectively)). This process generates short SRT activated sludge stream, which should be highly degradable. However, the evaluation of anaerobic digestion of short SRT sludge has been ...

No pipeline, no problem
Colony Farm - First virtual pipeline of this scale Upgraded biogas makes a very efficient source of renewable energy, biomethane. Biogas can be produced from various organic resources of which the most common are agricultural waste, municipal waste, landfills, and wastewater treatment facilities. Some of these sites are in very remote areas that do not have access to a national grid to inject ...

Biogas-to-biomethane upgrading plant
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 ...
