The relationship linking sulfide production rate and wastewater quality in terms of its biodegradability was studied using a pilot plant pressure sewer (inner diameter: 102 mm, length: 47 m). Furthermore, anaerobic transformations of wastewater organic matter were investigated. Wastewater characterization based on oxygen utilization rate (OUR) measurements and VFA analyses was employed. As wastewater quality parameters essential for the sulfide production, COD components and dissolved carbohydrate were focused on. Readily biodegradable substrate and fermentable, readily biodegradable substrate were better parameters than traditional dissolved COD for the prediction of sulfide production rates in a pressure sewer. From the results obtained, it was possible to integrate the sulfide production process with the transformation processes of wastewater organic matter in pressure sewers.
