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 …

Effect of bidens pilosa L in sulfate removal from industrial wastewater in a hydroponic system
… from human activities such as discarding sulfate-rich wastes into natural water resources leads to the introduction of sulfate and other toxic substances like heavy metals. This poses as a threat to human health and the environment since consumption of sulfate concentration greater than …

Sulfate removal from water produced during CO2 enhanced oil recovery, coal-bed methane recovery, and mining operations using anion exchange resins
… on the order of 100,000 mg/L, and also high sulfate concentrations (up to 900 mg/L). Dissolved sulfate can cause stress corrosion cracking in steam turbine blades at concentrations as low as 8 mg/L. A certain level of treatment must be done before reuse in power plants is a viable option. …

Barium carbonate treatment of sulfuric acid wastewater
Two methods of removing sulfates from sulfuric acid wastewater through the addition of barium carbonate and the formation of a barium sulfate precipitant were investigated. Optimization of barium carbonate dosage, reaction time and mixing conditions was accomplished for each method prior to …

Biological Treatment of Reclamation of Industrial Wasterwater From Post-Combustion Carbon Capture
… treatment of two contaminants: amines and sulfates. The main objective of this study is to design and develop an effective biological system to treat CCS wastewater to a quality that can be recycled back to the CCS process economically. The two biological treatment systems used were the …

Physiochemical Treatment Options for High-Conductivity Coal Mining Runoff
… lime-soda softening, and the Cost Effective Sulfate Removal (CESR) process. Both cation (H⁺ exchanger) and anion (Cl⁻ exchanger) exchange media were tested separately in batch reactors, which resulted in a higher effluent SC than initial SC. The softening method investigated, excess lime-soda …

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 …
