SEWAGE SLUDGE MANAGEMENT AND LEGAL ASPECTS RELATED WITH THEM

All sludge management methods can be divided into two basic groups: high-temperature processing, and bio-
logical and chemical stabilization. In 2010, approx. 40% of the sludge was stored in landfills and approx. 36%
of sludge was used in agriculture in EU27. The sludge management method is conditioned by the compliance
with legal acts concerning sludge management. The most important of these include: Directives of the European
Parliament and the Council number: 80/68/EEC, 2008/50/EC, 86/278. The directives listed above contain infor-
mation about allowable concentrations of pollutants, which can be released into the environment, and the most
important declarations concerning sludge management. Various analytical techniques can be used during the
monitoring of the sludge managed, the most frequently used ones include chromatographic, spectroscopic tech-
niques and laboratory toxicity tests. Additionally, analytical chemistry is a powerful tool which allows for designing
an ecologically and economically justified management method in a rational manner.
Keywords: Sludge management, thermal sludge stabilization, non-thermal sludge stabilization.
