Anaerobic Digester - Definition, Glossary, Details - Oilgae
Anaerobic Digester is one of the most commonly used method for treating organic sludges generally resulting from the biological treatment of wastewaters through activated sludge processes. Under this process the organic sludge is treated in the absence of oxygen to reduce both the quantity and odor of sludges by breaking down the organic matter. The resultant sludge is rich in nutrients and organic matter which can improve the soil conditions if applied as soil supplement. - Source

Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. The process is widely used to treat wastewater sludges and organic wastes because it provides volume and mass reduction of the input material. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere - Source
How Anaerobic Digestion (Methane Recovery) Works - Biodigesters recover methane from animal manure through a process called anaerobic digestion. Here's how it works.
Anaerobic Digestion and Bio-Gas - Anaerobic digesters convert the energy stored in organic materials present in manure into biogas. Biogas can be fed directly into a gas-fired combustion turbine. The type of turbine most often used for small-scale electricity production is the micro turbine. Combustion of biogas converts the energy stored in the bonds of the molecules of the methane contained in the biogas into mechanical energy as it spins a turbine. The mechanical energy produced by biogas combustion in an engine or micro turbine spins a turbine that produces a stream of electrons, or, electricity.
Briefing Anaerobic digestion - Anaerobic Digestion (AD) is a biological process that happens naturally when bacteria breaks down organic matter in environments with little or no oxygen. It is effectively a controlled and enclosed version of the anaerobic breakdown of organic waste in landfill which releases methane.
What is Anaerobic Digestion - Anaerobic digestion is the natural breakdown of organic materials into methane and carbon dioxide gas and fertiliser. This takes place naturally, or in an anaerobic digester.
