Abstract
Process and apparatus for the continuous anaerobic decomposition of organic compounds in an aqueous liquid is effected, in accordance with the invention, in a fixed-bed reactor by microorganisms, which are grown upon a support with the admixture of recycled reactor discharge in such an amount that practically uniform conditions exist throughout the reactor. The volume/time yield can be increased to a surprisingly large extent by means of the process if, after breeding sufficient adhering microorganisms with a residence time equal to or greater than 50% of the doubling time, an iterative reduction is efected in the residence time with the onset of equilibrium conditions at each stage until the volume/time yield can be increased no further.
