Abstract
The anaerobic sludge digestion process is not a recent development. At least 100 years ago in France,Louis H. Mouras designed and constructed fermenters to liquefy the sludge obtained from domestic wastes.
Since the turn of the century, the anaerobic fermentation process has been used extensively in the treatment of waste-water solids.
The necessity of preventing pollution of water resource, as a consequence of the rapid increase in human waste, demands adequate treatment of liquid wastes from domestic and industrial sources. For this purpose, the anaerobic digestion process can play an important role as a method for stabilizing and eliminating wastes such as dissolved and suspended organic materials. It has been pointed out that the anaerobic process is characterized by a high degree of waste stabilizing, low production of biological sludge, low nutrient requirements, no oxygen requirements, and production of methane gas as a useful by-product.
The advantage of three-stage(or three-phase) anaerobic digestion as compared with single-stage digestion have been extensively discussed. The major question is whether or not a three-stage process will use the total reactor volume as effluently as a single-stage process. In this respect the data from the digest reactor are promising.
