Biogas is mainly produced from the anaerobic fermentation of biomass, containing methane
with an extensive range between about 50% and 70%. Higher methane content biogas has …

The generation of toxic, malodorous, and corrosive hydrogen sulfide (H 2 S), which can
cause serious hygiene and health problems and damage biogas plants, is inevitable in …

Conductive materials application in anaerobic digestion containing sulfur gains increasing
attention due to their multifunctional effects in promoting substrate degradation, methane …

Expansion of modern industry coupled with a lack of effective treatment systems has
resulted in excessive release of toxic and odorous pollutants such as hydrogen sulfide (H 2 …

This review highlights the recent technologies of H2S removal from wastewater in the
petroleum refinery. H2S is a harmful, putrid, and hazardous gaseous compound. The main …

Direct interspecies electron transfer (DIET) between exoelectrogenic fatty acid-oxidizing
bacteria and electrotrophic methanogens has recently been discovered, and studies have …

The high volume of flowback water (FW) generated during shale gas exploitation is highly
saline, and contains complex organics, iron, heavy metals, and sulfate, thereby posing a …

Biochar (BC) is a low-cost and electroactive adsorbent for removing sulfide in aqueous
media, which toxifies aquatic organisms and corrodes water treatment facilities. However, it …

Mn x O y coated over TiO 2 nanotube array substrate was doped with Mo and polyaniline
(PANI) and applied for electrochemical desulfurization of concentrated sulfide (HS−) …

It is preferred to recycle resources and energy from pollutants rather than simply remove
them. An energy-free concept for sulfide-containing wastewater utilization is presented here …
