Enhanced Microbial Sulfate Removal Through a Novel Electrode-Integrated Bioreactor
In northeast Minnesota, elevated levels of sulfate in freshwater systems is a topic of great interest, due to potential adverse impacts to wild rice ecosystems. Sulfate may contribute to methylmercury production and eutrophication in certain conditions. Increased interest has emerged for developing …

A prototype dynamic model for the co-treatment of a high strength simple-organic industrial effluent and coal-mine drainage
This research study's the use of biological sulfate reduction technologies for the treatment of Sasol Secunda's coal-mine drainage (CMD) using Fischer-Tropsch Reaction Water (FTRW) as a cost-efficient carbon source. The research aims to develop a prototype dynamic model that describes this …

The modelling of a falling sludge bed reactor using AQUASIM
… modelling of anaerobic digestion and biological sulfate reduction, to select rate equations from the literature that would simulate the various interactions taking place in the FSBR being fed a mixture of organic matter and acid mine drainage, and to investigate the trends obtained …

Sulfide immobilization with taconite tailings: products, capacity, and stability
Excess sulfate (SO42-) may negatively impact certain freshwater ecosystems. In Minnesota, wild rice (zizania palustris) is threatened by excess sulfate. Several technologies are being researched and developed to remove sulfate from waters where wild rice grows. One of which is a two-part active …

Biological and Membrane Treatment Applications for the Reduction of Specific Conductivity and Total Dissolved Solids in Coal Mine Waters
… on SC for all mining operation outfalls. Sulfate typically has the greatest dissolved ion presence in coal mine waters. In literature examining the treatment of mine waters, SC and TDS analysis is typically not reported. The technologies examined in this study were nanofiltration membrane …

Bioremediation of Effluent Water in a Coal Ash Disposal Area: Optimizing Microbial Sulfate Reduction
… This study focuses on the issue of elevated sulfate concentrations at the Martin Lake Steam Electric Station (MLSES) A-I Disposal Area in Panola County, Texas, where CCR are disposed of in a permanent landfill. Currently, this site is exceeding its regulatory limit of sulfate concentrations …

Extension and verification of the PWM_SA model to incorporate SANI-specific bioprocesses using experimental data from the Hong Kong SANI saline sewage treatment pilot plant.
… adapting the PWM_SA model to incorporate sulfate reduction, autotrophic denitrification, and nitrification processes characteristic of the SANI system, focusing on achieving accurate mass balance across key chemical species and overall internal consistency. Specifically, the model …
