SRS - Sludge Reduction Study
Abstract
Sludge treatment and disposal systems are entering a period of dramatic change, driven mainly by environmental legislation. Due to the construction of new sewage treatment plants and an increase in the number of sewerage connections, the total production of municipal sewage sludge will increase considerably. The resulting challenge that any sludge treatment strategy has to face, is how to maintain cost-effective and secure methods of sludge treatment, while simultaneously engendering public confidence in all disposal and recycling options. This problem is not only faced by Europe but also by the developing countries. In China a phased investment program of wastewater interception and treatment has been initiated by the government under the support of the World Bank to address an increasingly problematic environmental situation. It was recognized that improvement of waste water treatment is strongly associated with appropriate sludge treatment technologies. The study - a co-operation with a large Austrian water company - evaluates the various options for the reduction or treatment of surplus sludge with special emphasis on the local situation of the cities of Shanghai and Chengdu. Within the study an innovative process was developed and tested at the laboratory scale. Due to the highly promising results a pilot treatment system is operated at the WWTP of Tulln for further investigations.
