Understanding the Biorealis Systems Anaerobic Methane Digester
The process by which anaerobic bacteria decompose organic matter into methane, carbon dioxide, and a nutrient-rich sludge involves a step-wise series of reactions requiring the cooperative action of several organisms. In the first stage, a variety of primary producers (acidogens) break down the raw wastes into simpler fatty acids. In the second stage, a different group of organisms (methanogens) consume the acids produced by the acidogens, generating biogas as a metabolic byproduct. On average, acidogens grow much more quickly than methanogens. They are also much hardier organisms, able to survive a broader range of temperature and pH conditions…
