Sewage Sludge Disposal in Switzerland
Sewage sludge was used as fertilizer in agriculture in Switzerland since the begin ning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow d...
متن کاملSustainability of Domestic Sewage Sludge Disposal
Activated sludge is now one of the most widely used biological processes for the treatment of wastewaters from medium to large populations. It produces high amounts of sewage sludge that can be managed and perceived in two main ways: as a waste it is discharged in landfill, as a fertilizer it is disposed in agriculture with direct application to soil or subjected to anaerobic digestion and comp...
متن کاملEnvironmental and Landfill Operational Aspects of Co-disposal of Dewatered Sewage Sludge and Municipal Solid Waste
The co-disposal of dewatered sewage sludge and municipal solid waste may cause significant impacts (such as total and differential settlement, slope stability of the waste, and leachability) on landfill operations and the subsurface environment. The objectives of this study were to investigate the co-disposal of dewatered sewage sludge and municipal solid waste with respect to their consolidati...
متن کاملUsing Vitrification for Sewage Sludge Combustion Ash Disposal
The aim of this paper is to show possibilities for effective processing of hazardous waste using the vitrification method, which is recommended for disposing of ash from the combustion of sewage sludge and developing a process for the conversion of waste to a sustainable and environmentally safe product. The use of vitrification solves the problem of utilizing some hazardous waste by simultaneo...
متن کاملToward a consensus view on the infectious risks associated with land application of sewage sludge.
The science linking processed sewage sludge (biosolids) land application with human health has improved in the last ten years. The goal of this review is to develop a consensus view on the human health impacts associated with land-applying biosolids. Pre-existing risk studies are integrated with recent advances in biosolids pathogen exposure science and risk analysis. Other than accidental dire...
