Anaerobic digestion process which has long been known to successfully reduce the
organic content of sludge is one of the most common alternatives to meet
pathogen reduction requirements for particular classes of biosolids. However, it has
recently been reported that, significantly higher densities of indicator bacteria have
been measured in dewatered cake samples compared to samples collected right
after anaerobic digestion. In addition, this increase in bacterial population has been
commonly observed after centrifugation but not after belt filter dewatering. Even
though several theories have emerged to explain this occurrence, with the use of
molecular tools such as Quantitative Polymerase Chain Reaction (Q
