In sewer systems where anaerobic conditions are present, sulfate-reducing bacteria reduce
sulfate to hydrogen sulfide (H 2 S), leading to sewer corrosion and odor emission. Various …

Raw biogas generated in the anaerobic digestion (AD) process contains several undesired
constituents such as H 2 S, CO 2, NH 3, siloxanes and VOCs. These gases affect the direct …

Although the biocidal effect of calcium peroxide (CaO 2) has attracted increasing attention in
wastewater and sludge management, its potential in the reduction of sulfide and methane …

Chemical dosing is the most used strategy for sulfide and methane abatement in urban
sewer systems. Although conventional physicochemical methods, such as sulfide oxidation …

Although the dose of biocides to sewers could control sulfide and methane production, the
high resistance of sulfate-reducing bacteria (SRB) to biocides would increase dosing …

Nitrate or nitrite-dependent anaerobic methane oxidation (n-DAMO) is a microbial process
that links carbon and nitrogen cycles as a methane sink in many natural environments. This …

The increasing global demand for fatty products, population growth, and the expansion of
food service establishments (FSEs) present significant challenges for the wastewater …

Sulfide and methane production are a major concern in sewer management. Many solutions
with the use of chemicals have been proposed yet incurring huge costs. Here, this study …

Ferric chloride (FeCl 3) served as a solid acid has attracted attention recently. However, the
feasibility of FeCl 3 combined with nitrite for free nitrous acid (FNA) generation in controlling …

In recent years, large quantities of pharmaceuticals and personal care products (PPCPs)
have been discharged into sewers, while the mechanisms of PPCPs enrichment in sewer …
