The fate of mercury in an activated sludge pilot plant

Abstract

The objectives of this thesis were the study of the mercury contaminated wastewater input effects at the activated sludge pilot plant and the examination of merkury's fate during the activated sludge process. In this thesis 17 of the most important physical, chemical and biological parameters of the pilot plant were measured during the seven (7) series of experiments. The main conclusions of this thesis are: the introduction of wastewater which was contaminated with Mercury (10-600 μg/L), into the plant affect statistically significant: a) The total bacterial number in the aeration tank, b) the growth rate of several bacterial species in the aeration tank, c) the size distribution of the suspended solids in the aeration tank and at the outlet of the plant and d) the organic loading removal ability of the plant. The most important specie of the mercury during the activated sludge process was the particulate mercury. There was not detected methylation of the incoming inorganic mercury ...
