Abatement of Helminth Eggs and Bacterial and Viral Indicators in Soil after Land Application of Treated Sludges
2013
Journal of Water Resource and Protection
The reduction of helminth eggs, fecal coliforms and somatic coliphages present in sewage sludge after treatments and abatement by application to soil was determined. Traditional stabilization processes produced small changes in the concentrations of the parameters studied. In contrast, thermal treatments and liming produced dramatic reductions. Fecal coliforms were the most affected by both types of treatments; somatic coliphages showed some persistence after 30 minutes at 60˚C; and both
