Abstract:

The Northeast Ohio Regional Sewer District completed a sampling and model calibration exercise for tracking the fate of twelve metals through the Southerly Wastewater Treatment Center, including incinerator and associated ash handling processes. The modeling effort, using the TOXCHEM+ fate software, was supported by a week-long inter-stage sampling program for total and dissolved forms of mercury, selenium and silver, which were not present in the existing TOXCHEM+ modeling database. Results of the sampling program were used to calibrate the fate model. The modeling effort showed that over 80% of the influent loadings of mercury and silver exited the plant in fly ash; less than 7% of the influent loadings of the two metals was discharged in the plant final effluent, while approximately 10% of the input loadings was retained in the ash lagoon. By comparison, just over half (58%) of the influent loading of selenium left the plant in fly ash, while 37% was discharged in the final effluent.
