Anaerobic Processes — Sulfide Formation and Integrated Modeling

Anaerobic conditions are traditionally a major concern when dealing with microbial-induced transformations of wastewater in a collection system. The problem is primarily associated with the risk of hydrogen sulfide and odorous organic compounds. The corresponding problems appear as concrete and metal corrosion, health-related impacts and malodors. Such in-sewer process-related problems have been reported as early as over 50 years ago (Parker, 1945a, 1945b Pomeroy and Bowlus, 1946). 

Anaerobic processes — related to both the sulfur and the carbon cycles — are, therefore, important in sewers. The interaction between these processes and the aerobic transformations of the wastewater may be even more interesting for the functioning of the urban wastewater systems. 

During the 1960s and 1970s, the problems related to hydrogen sulfide in 

It is not surprising that the main theoretical work and practical development of models and procedures in this respect took place in countries like the United States, Australia and South Africa. These countries have extended sewer networks, transporting wastewater at elevated temperatures (approximately 20-30°C). Also, the United Kingdom contributed to this development. 

Example 6.1 provides small histories of how things may develop when process aspects are not taken into account.
