The North-West University has developed a method in which municipal wastewater is treated to remove ammonia and phosphate while simultaneously recovering struvite as a byproduct. Struvite is used to reduce the acidity of acidity of the acid mine drainage water which leads to precipitate metal
Chalcopyrite is a common but low-grade copper ore, and NWU researchers have developed an innovative method to improve copper dissolution and extraction from this mineral. This is achieved by harnessing galvanic interactions between chalcopyrite and magnetite, they achieved more efficient copper
The North-West University (NWU) has developed and patented a method for producing hydrogen via hydrolysis, using an activated aluminium compound. Technology Benefits: Aluminum also can be recycled after the hydrogen production process. Hydrogen can be produced under high pressure. By-products are
This technology utilises a microchannel reactor for the decomposition of ammonia, comprising two chambers: one for exothermic combustion of ammonia to generate heat. A second chamber of the reactor with a second catalyst receives a second stream of ammonia to provide endothermic decomposition of the

The technology relates to a new generation of telecommunications and data processing technology with improved wavelength sensitivity in the visible and near-infrared wavelengths range rather than microwave communication in 2–4 GHz. The technology provides the realisation of optical sources (LEDs)

A system which harvests thermal energy from various sources such as sunlight, cars, power plants, factories and other industries, and converts it into electricity. The harvested heat energy is stored in a storage tank, with water used as an energy storage medium. This then flows along a gradient to
