Enhanced Anaerobic Digestion Using Fenton Reagent

Ithaca Area Wastewater Treatment Facility
Ithaca, New York

The results of the Fenton reagent treatment of biosolids at a bench scale and at a full scale
operation, as well as the cost-benefit analysis, are presented here. We compare the results of one
year of full-scale operation of Fenton reagent treatment during 2008 against the normal operation
parameters for the period 2005 – 2007. The treatment of biosolids with Fenton reagent was tested
in a full-scale reactor at the Ithaca Area Wastewater Treatment Facility, IAWTF. The Fenton
reagent treated biosolids were returned back to an anaerobic digester for additional digestion.
The most relevant results were the reduction in the amount of final residual biosolids for disposal
(11.5% reduction), the increase in the percent solids content of the final residual biosolids (7.5%
higher), and a higher energy cogeneration output (13.0% higher specific biogas production, &
13.0% higher heat output). The net economic benefit was $78,000.00 per year.
