Septic Tanks: Are they Anaerobic Digesters?

We have been asked the question of whether Septic Tanks are Anaerobic Digesters several times recently. The short answer is yes. They utilize the anaerobic digestion process for the treatment (albeit only partial at a slow rate, and not to watercourse discharge standards) of sewage. They are used from isolated locations where inhabited dwellings are […]

Covered Anaerobic Lagoon Process and Manure Ponds for Biogas

A simple, low capital cost, anaerobic digestion process using the Covered Anaerobic Lagoon Process The process which we have named as the “Covered Anaerobic Lagoon Process” has been around since the development of geomembrane lining systems for low cost water storage. This method of encapsulating a lagoon to make use of the biogas has been […]

What is a Biogas Power Plant?

A Biogas Power Plant is essentially another name which has been coined recently for an anaerobic digestion plant. These are, also known as biogas digesters. As any technology becomes more successful and reaches a wider audience, so does it generate new names and the anaerobic digestion technology sector is no exception. To cover the entire […]

Biogas Production in China – Agricultural, Domestic and at Community Scale

Biogas production in China from agricultural organic waste is extensively utilised already and has potential to be developed further, to provide additional energy, and this is also highly sustainable energy for the nation. Most speak of Chinese biogas for the Agricultural, Domestic and Community uses. This article is limited to those applications. Introduction Even as […]

How Ultrasonic Disintegration of Sewage Sludge Improves Wastewater Treatment Plant Biogas Outputs

Sewage sludge is notoriously slow to digest. Ultrasonic disintegration provides an environmentally responsible way to improve biogas output. Unsurprisingly wastewater treatment works biogas plant operators have been first to adopt ultrasonic disintegration. As the technology becomes further developed there is no reason why the AD industry won’t also adopt it’s use for other similarly slow […]

Biogas Upgraders – The Best 3 Biogas to Biomethane Technologies

Biogas upgraders are facilities that are used to concentrate the methane in biogas to natural gas standards. The upgrading systems remove carbon dioxide (CO₂), hydrogen sulphide (sulfide), water and other trace concentration contaminants from the biogas. Upgraded biogas is called “biomethane.” What are the three top performing biogas upgrading technologies? There are in fact 8 […]
