An integrated aerobic/anaerobic approach for prediction of sulfide formation in sewers

A conceptual framework for microbial transformations of organic matter and sulfur components in sewers has been developed. This concept is a new basis for integrated process engineering analysis, planning, design and management of the urban wastewater system. Based on the concept, a model (WATS, WastewaterAerobic/anaerobic Transformations in Sewers) has been developed for simulation of wastewater quality transformations and sulfide formation in sewers. The paper will outline the concept and give examples of engineering applications. The model has been used as a design tool for simulation of carbon and sulfur wastewater transformation under dissolved oxygen limited conditions in a 50 km intercepting gravity sewer being planned in the Emscher catchment, Germany.
