Integrating Microbial Fuel Cells (MFCs) into the treatment of sulphate-rich wastewater
… reduction and sulphide oxidation to yield a sulphur product. Sulphate Reducing Bacteria (SRB) mediate the biological sulphide reduction. Chemical and biological sulphide oxidation takes place in a Floating Sulphur Biofilm (FSB) on the surface of the reactor and is mediated by Sulphide …

A novel semi-passive process for sulphate removal and elemental sulphur recovery centred on a hybrid linear flow channel reactor
… followed by its partial oxidation to elemental sulphur, which is stable and has potential as a value-added product. A promising approach to achieve partial oxidation is the use of sulphide oxidising bacteria (SOB) in a floating sulphur biofilm (FSB). These biofilms develop naturally on the …

Optimisation of a linear flow channel reactor for semi-passive, simultaneous biological sulphate reduction and partial sulphide oxidation
… it from the stream in gaseous form or as a solid sulphur-containing compound. Alternatively, it can also be used, in part, to precipitate metals present within ARD waters. Key challenges associated with SRBbased bioremediation include the cost of the supplemented electron donor needed for SRB to …

Investigation of alternative carbon sources for the biological treatment of synthetic sulphate-laden water and mine impacted water in a linear flow channel reactor
… the potential to convert sulphate to elemental sulphur, touching on waste valorisation as sulphur is a value-added product. However, BSR systems require supplementation with organic carbon and are characterised as slow, while partial oxidation of sulphide is difficult to control in many reactor …
