What is an Aerobic Digester?
Aerobic digesters are used in wastewater treatment plants for processing wastewater and removing harmful chemicals, pollutants and toxins. A few of the advantages of aerobic digesters include; low first cost to install, simple to operate and while some professionals in the industry believe lack of biogas (methane) production may be an advantage, we believe this is a definite DIS-advantage.
What is an Anaerobic Digester?
An anaerobic digester is a system that takes an organic waste stream and through the process of anaerobic digestion (meaning without oxygen), microorganisms break-down the waste stream which generates biogas in the process. The biogas cannot be used due to the large amount of impurities it contains, so the biogas must cleaned through a biogas to biomethane process after which, the clean biomethane, often referred to as "renewable natural gas" is used just as natural gas, methane or CH4.
The right anaerobic digester and "feedstock" are critical components to optimum production of biomethane which can fuel your own cogeneration or trigeneration power plant.
