Section 40 of the Code of Federal Regulations Part 503 regulates the land application of sewage sludge based on pathogen content and sets standards for nine inorganic chemicals. It is believed that the Part 503 standards are protective of human health and the enviro...

متن کاملEcotoxicological effect assessment and risk characterisation of selected contaminants in sewage sludge
Ž .Linear alkylbenzene sulphonates LAS are a group of anionic surfactants, characterised by having both ahydrophobic and a hydrophilic group. LAS is one of the major ingredients of synthetic detergents and surfactants andis used world-wide for both domestic and industrial applications. LAS is relatively rapidly aerobically degraded, butonly very slowly or not at all degraded und...
متن کاملSewage 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 کاملComparative assessment of municipal sewage sludge incineration, gasification and pyrolysis for a sustainable sludge-to-energy management in Greece.
For a sustainable municipal sewage sludge management, not only the available technology, but also other parameters, such as policy regulations and socio-economic issues should be taken in account. In this study, the current status of both European and Greek Legislation on waste management, with a special insight in municipal sewage sludge, is presented. A SWOT analysis was further developed for...
