Abstract
Process water from the entirely closed water system of a wastepaper reprocessing mill was examined for its content of different groups of microorganisms. Comparison with waste-paper reprocessing mills with nonclosed systems and concomitant higher specific water consumption showed that system closing is associated with a marked increase in the number of anaerobic microorganisms; Bifidobacteria were found to be the most frequently represented bacteria. The development of the microflora in the entirely closed water system was studied after total replacement of the process water with fresh water. Constant levels of anaerobic microorganisms were recorded after a lag period of 15 days. Gas chromatographic analyses showed that the process water from the entirely closed system contains significant amounts of metabolic products of anaerobic microorganisms.
