Anaerobic Digester
In waste treatment facilities, it is a dedicated unit used for controlling the anaerobic decomposition of organic material.
Digester: A closed tank for wastewater treatment, in which bacterial action is induced to break down organic matter.
Diluting water: Distilled water that has been stabilized, buffered, and aerated. Used in the BOD test.
Digester: In wastewater treatment, a closed tank; in solid-waste conversion, a unit in which bacterial action is induced and accelerated in order to break down organic matter and establish the proper carbon to nitrogen ratio.
digester In wastewater treatment, a biochemical oxidation or conversion unit operation in which bacterial action is induced and accelerated in order to break down organic matter forming carbon dioxide and water in the presence of oxygen (aerobic) ...
Sludge Digester: Tank in which complex organic substances like sewage sludges are biologically dredged. During these reactions, energy is released and much of the sewage is converted to methane, carbon dioxide, and water.
Anaerobic digester
a tank or vessel which excludes oxygen and in which a sludge or liquid is modified by the action of anaerobic bacteria ...
While it is conceivable that home methane digesters could catch on as an alternative source of household energy, the idea probably isn't practical.
anaerobic igester"anaerobic digester = collector of gases from organic decomposition for the purpose of reuse in the production of heat or electricity
anthropogenic = attributable to human activity ...
Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs.
How It Works ...
Suspended growth reactor A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.

facility where the organic component of municipal solid waste is decomposed under controlled conditions; 2.an aerobic process in which organic materials are ground or shredded and then decomposed to humus in windrow piles or in mechanical digesters, ...
Sludge: heavy, slimy residue remaining from the treatment of municipal and industrial water and wastewater. Digested sewage sludge remains after decomposition under controlled temperature, pH, and mixing in a digester tank.
