ResumoAbstract 1. A model treatment plant has been developed for treating wastes with a high organic content utilizing photosynthetic bacteria. 2. The decontaminated sludge after treatment with photosynthetic bacteria, could be utilized as animal feed supplements and organic fertilizers. 3. The process of utilizing photosynthetic bacteria for treatment of digested sludge holds great promise for the future. Photosynthetic bacteria are common throughout the world and are characterized by their ability to assimilate carbon dioxide and fix molecular nitrogen, utilizing solar sources of energy. ( Gest, Kamen 1949 ; Kobayashi, Haque, 1971 ; Kondrateva, 1963 ; Pfennig, Trüper, 1974 ; Van Niel, 1944 ) The important role of this group of microorganisms in the purification of polluted natural waters is well known. ( Kobayashi, 1972 ; Kobayashi, Tchan, 1973 ; Kobayashi, 1975 ; Kobayashi et al. 1976 ) In the present report a model treatment plant has been described for utilizing these bacteria for decontaminating waste waters containing high concentrations of organic matter, and for utilizing these microbial by-products. This report includes also descriptions of the operation of an ideal treatment plant.
