“…The results showed enhanced nitrite accumulation and N2O emissions with higher proportions of blackwater. Pikaar et al (2015) reviewed the electrochemical strategies proposed over the past few years for the removal of dissolved and gaseous H2S including discussions on advantages and disadvantages, technical aspects, economic potential, the potential for recovering sulfide or sulfur from wastewater, and the key challenges to enable full-scale implementation.…”

A review of the literature published in 2015 on topics relating to gaseous emissions from wastewater facilities is presented. This review is divided into the following sections: odorant emissions from wastewater treatment plants (WWTPs); greenhouse gas (GHG) emissions from WWTPs; gaseous emissions from wastewater collection systems; physiochemical odor/emissions control methods; biological odor/emissions control methods; odor characterization/monitoring; and odor impacts/ risk assessments.

“…In all platforms, Bioresource Technology ranked top in number of MBR papers published (12%). Relevant review articles are available on recent progress and developments of MBR technologies, including those for nutrient/pollutant removal and recovery (Kelly and He, 2014), improvement of micro-scale MBR architecture for performance improvement (ElMekawy et al, 2014), use of MBR for abatement of hydrogen sulfide (Pikkar et al, 2015), as a desalination device (Subramani and Jacangelo, 2015) and as a bio-factory (Mohan et al, 2014). Besides, the anaerobic submerged MBR were studied for enhanced methane production (Robles et al, 2014;Gao et al, 2014a,b;Xie et al, 2014;Ding et al, 2014b).…”

“…A major concern when upgrading these gas streams in the context of CCU is that H 2 S, as one of the more common impurities, can already be toxic for microorganisms, both in pure culture and within microbial communities, at concentrations of a few ppm (Wu et al , 2015). Several strategies for H 2 S removal exist (Mandal et al , 2004; Pikaar et al , 2015; Vaiopoulou et al , 2016), but these processes will only lower the concentration of H 2 S and a fraction of it will inevitably end up in a gas fermentation reactor, where it can affect the microbial activity. The amount of H 2 S in the fermentation reactor will be dependent on the prior H 2 S removal steps (Kristmannsdóttir et al , 2000).…”

Biological CO 2 sequestration through acetogenesis with H 2 as electron donor is a promising technology to reduce greenhouse gas emissions. Today, a major issue is the presence of impurities such as hydrogen sulfide (H 2 S) in CO 2 containing gases, as they are known to inhibit acetogenesis in CO 2 -based fermentations. However, exact values of toxicity and inhibition are not well-defined. To tackle this uncertainty, a series of toxicity experiments were conducted, with a mixed homoacetogenic culture, total dissolved sulfide concentrations ([TDS]) varied between 0 and 5 mM and pH between 5 and 7. The extent of inhibition was evaluated based on acetate production rates and microbial growth. Maximum acetate production rates of 0.12, 0.09 and 0.04 mM h -1 were achieved in the controls without sulfide at pH 7, pH 6 and pH 5. The half-maximal inhibitory concentration (IC 50 qAc ) was 0.86, 1.16 and 1.36 mM [TDS] for pH 7, pH 6 and pH 5. At [TDS] above 3.33 mM, acetate production and microbial growth were completely inhibited at all pHs. 16S rRNA gene amplicon sequencing revealed major community composition transitions that could be attributed to both pH and [TDS]. Based on the observed toxicity levels, treatment approaches for incoming industrial CO 2 streams can be determined.
