The technology involves a method and an apparatus for treating a fluid, using nanoscience. Impurities in the fluid are trapped by 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 less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline

The invention relates to a membrane technology developed using polymeric material, to recover crude oil found in water due to spillages. Although several techniques have been employed for removing crude oil from bodies of water, these techniques are either focused on dissolving the spilled oil

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 continues to lag behind. This invention exhibits advantages

The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

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

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

Green Coal is environmentally friendly coal briquettes produced from discarded fine coal, bio-char material, and proprietary chemical binders. The briquette reduces sulphur emissions during combustion by approximately 50%, while also increasing the burning effectiveness. The bio-char addition to the

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

Coarse particle transportation is essential for moving slurries, or fluids containing very high concentrations of pulverised solids, for example, hydraulic transport of coal ore or waste materials. Due to a scarcity of water and a high concentration of the solid particles, pipe blockages are common
