:: Acid Mine Drainage


A newly developed membrane used to separate waste from water could become key in the treatment of pollutants ranging from acid mine drainage to oil-containing wastewater, as well as in processes ranging from desalination to kidney dialysis.

The research has been published in a prestigious international journal, coinciding with World Water Day and falling within South Africa’s National Water Week.

The technology - which was developed by a team of researchers from Wits University, in collaboration with NASA - will make it easier to filter pure water from waste produced during mining, oil and gas exploration and production, and nuclear exploration, to name a few. Even medical purification processes such as kidney dialysis could benefit.
