It is quite rare to see, and it is based upon the idea that the particles in any sludge are gradually falling within the liquid they are in. This group of bacteria is responsible for the first stage of anaerobic digestion - hydrolysis and acidogenesis. Owing to this fact, anaerobic processes may not able to degrade the organic matter to the level meeting the discharge limits for ultimate disposal. Many different anaerobic digester systems are commercially available.
