METHODS OF CHARACTERIZATION OF SEWAGE SLUDGE
Sewage sludges from different sources can exhibit wide differences in their physical, chemical and biological characteristics. In practical terms, this means that their behaviour in the various processing operations (pumping, thickening, stabilization, conditioning, dewatering) and their characteristics after processing can vary in an unpredictable way. To arrive at the most appropriate choice, specification and method of operation of a sludge processing plant, it is usually desirable to characterize the particular sludge in respect of the relevant processing parameters using laboratory or pilot scale tests. The development of tests for characterizing various sludge parameters has been proceeding for some years in a number of countries. From the commencement of the COST 68 Concerted Action on Sewage Sludge, there has been an effort to coordinate this area of research and in particular to identify new parameters of importance and to standardize definitions and test methods. The characterisation tests relating to sludge processing have been the special responsiblity of the COST 68 Working Party. This working party with the support of the Commission of the European Communities, organised a Workshop in Dublin on 6 July 1983. The papers presented cover most of the more recent work within the COST 68 participating countries. This volume contains the proceedings of the Workshop together with some brief conclusions contributed by members of Working Party 1. It is hoped that the information provided will be valuable both to plant designers and operators and to those involved in research on sludge processing techniques.
