Abstract
Several anaerobic reactor types are utilised for waste treatment by biological means; these can be broadly divided into two groups, namely the fixed-film reactors and the non-attached growth systems. The biomass of the former comprises bacteria attached as films to inert supportive media; the latter depend for their operation on the metabolic activity of microorganisms suspended as flocs or granules in the reactor vessel. The bacteria in suspended growth processes must form flocs to remain in the reactor, and the efficiency of non-attached biomass systems is to a great extent dependent upon the floc-forming and settling abilities of the sludge inoculum used to initiate the anaerobic digestion process. The microflora of anaerobic reactors are almost exclusively bacterial; although protozoa may be present, they are generally introduced with the influent and play no active part in the degradation reactions [1].
