Continuous removal of sulfate and metals from acidic mining-impacted waters at low temperature using a sulfate-reducing bacterial consortium

Effect of Sulfate on the Release Rate of Al3+ from Gibbsite in Low-Temperature Acidic Waters

Biological Removal of phosphate from Synthetic Wastewater Using Bacterial Consortium

The biological phosphorus removal is a microbial process widely used for removing phosphorus fromwastewater to avoid eutrophication of water bodies. The study was aimed to screen the efficient phosphatereducing isolates and used to remove phosphate from synthetic wastewater using batch scale process. Thethree most efficient phosphate reducers were isolated and screened from eu...

Simultaneous sulfate reduction and copper removal by a PVA-immobilized sulfate reducing bacterial culture.

The effect of a sulfate reducing bacteria immobilized in polyvinyl alcohol (PVA) on simultaneous sulfate reduction and copper removal was investigated. Batch experiments were designed using central composite design (CCD) with two parameters, i.e. the copper concentration (10-100mg/L), and the quantity of immobilized SRB in culture solution (19-235 mg of VSS/L). Response surface methodology (RSM...

Kinetics of chalcopyrite galvanic leaching using sulfate media at the low temperature in the GalvanoxTM process

In this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°C to 50°C. In the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. Effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...

Removal of Metal Ions from Mine Effluents Using Bacterial Reactions by Sulfate Reducing Bacteria

Metals in mine effluents, especially metal mines, have been a major environmental concern. High mobility of the metals in solution and the subsequent lowering of discharge limits by the EPA have necessitated expensive chemical treatment of the effluent. Bacteriological reactions, particularly by Sulfate Reducing Bacteria, have been known to reduce metals content in water by precipitating them a...
