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

Postharvest table grapes are susceptible to fungal infection even when stored at the optimal temperature of −0.5°C. The most important pathogen of stored Table Grapes is grey mould, which is caused by Botrytis cinerea. Some countries fumigate their grapes with sulphur dioxide gas. However, if the

The Bambara Groundnut, or round bean, is widespread in Africa where it is known by various names. It has potential as a cash crop, owing to its nutritional composition, functional properties and antioxidant potential. Consequently, we at CPUT have used the Bambara Groundnut as a raw material to

The invention relates to a novel process of partial oxidation of un-agglomerated chromite ore in ferrochrome production processes. The process includes the steps: Providing a source of un-agglomerated chromite ore; subjecting the source of un-agglomerated chromite ore to pre-oxidation at a

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

The Agricultural Research Council - Vegetable and Ornamental Plants ( ARC-VOP), which has a solid reputation as a leader in sweet potato R&D, has developed a new variety Khumo orange-fleshed sweet potato. A 60-gram serving of boiled roots of variety Khumo, supplies the recommended daily allowance

Surfactants are amphipathic molecules with both hydrophilic and hydrophobic moieties that partition preferentially at the interface between fluid phases such as oil/water or air/water interfaces. Such characteristics confer excellent detergency, emulsifying, foaming, and dispersing traits, which

Currently, the ARC have three commercial cultivars, Ratel, Steenbok and Tredou. Ratel consists of a medium growth period whereas Steenbok consists of a short growth period with good drought tolerance making it suitable for areas with a dry climate. Tredou is the newest addition to the ARC cultivar

Fly ash, is a waste by-product from the coal-fired electricity generating stations. Power stations need to dispose of the fly ash in a safe and environmentally friendly manner, making the need to utilize fly ash important. The production of zeolites is one way to beneficiate the fly ash waste where
