Sludge in large quantity is generated as byproducts of wastewater treatment processes. Various approaches have been taken to treat sludge, such as land-filling, ocean dumping, or recycling for beneficial purposes. In the USA, about 60% of sludge generated is land applied as a soil conditioner or fertilizer. Due to increasing public concern on the safety of land-applied sludge, various sludge treatment technologies are being developed or under evaluation in order to improve the quality of sludge in terms of pathogen content, odor characteristics, accumulated organic micro-pollutants. This paper summarizes the results of various reported or on-going researches on the potential use of ferrate [Fe(VI)O42-] as a conditioning agent for sludge.
