TL;DR: Analysis of the long-term profiles of the sulfide uptake rate using a Gompertz model supported the enhanced corrosion activity and greater corrosion loss caused by wastewater inoculation, which coincided with the environmental conditions of increased levels of gaseous H2S and the concrete type.

TL;DR: It was found that the corrosion initiation time of both gas-phase and partially-submerged coupons was positively correlated with the gas phase H2S concentration, but only at levels of 10 ppm or below, indicating that sulfide oxidation rate rather than the H 2S concentration was the limiting factor during the initiation stage.

TL;DR: Examination of a corrosion layer within a suspended solution, containing the corrosion-causing biofilms, indicated that biological activity was severely decreased by the treatment, confirming the bactericidal effect of FNA on the microorganisms in the biofilm.

TL;DR: In this review, an overview is given of the different essential processes and technologies that enable closure of the nitrogen cycle in Bioregenerative Life Support Systems (BLSS).

TL;DR: It is demonstrated that iron-dosing to sewers can achieve multiple benefits including sulfide removal in sewers, phosphorus removal during wastewater treatment, and hydrogen sulfide (H2S) removal during biogas generation, therefore an integrated approach should be taken when considering iron salts usage in an urban wastewater system.
