A method and apparatus for treating a fluid utilising nanoscience. The impurities in the fluid are trapped by the charged nanoparticles. The fluid is contained in a reactor that includes a moving magnetic system. When the reactor is in use, the moving magnetic system excites the charged

The invention relates to the use of maghemite nanoparticles at pH < 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In a conventional way of AMD treatment, these pollutants are only removed at higher pH and requires costly alkaline chemicals

Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies. These problems are related to navigation, recreation, irrigation and hydropower generation. The complete

The invention relates to the design of a robust membrane for desalination using membrane distillation (MD). Although MD technology has advanced over the years, its industrial application for the treatment of brackish water and seawater is still lagging. This invention exhibits advantages over the

The technology is capable of treating high-temperature wastewater as a membrane for removing oil from wastewater One of the key challenges with membrane filtration devices is the issue of fouling and concentration gradient build-up on the surface of the membrane, which subsequently decreases its

Hydrogen and fuel cell technologies offer zero emissions and are a clean alternative to fossil fuels. HySA Systems, at the University of the Western Cape, have made improvements in the performance, reliability and cost competitiveness of fuel cell components and systems. These have been demonstrated

In the manufacture of textiles, clothing and leather goods, using a nanoparticle catalyst, this one-step wastewater treatment system activates a powerful oxidiser. This produces sulfate radicals in the wastewater which will degrade the inorganic pollutants. These highly reactive nanoparticles are
