Type

Peer-reviewed article not indexed in WoS or Scopus

Original Abstract

The contribution is devoted to the design of a sewage sludge disintegration unit with the capacity of 10.8 t/d of a liquid sludge (refers to a wastewater treatment plant capacity of 10,000 population equivalents). Used material properties and insights have been gained in experimental work. Based on measured data, a pressure vessel was proposed. Further, stress analysis, considerations concerning the vessel heating and an economical evaluation of the process was elaborated. In the evaluation, a payback period of approx. 15 y is determined, which emerges from the savings in sludge disposal.
