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

Hysteroscopy is a procedure that requires the direct visualization of the uterine cavity to diagnose and treat abnormal uterine conditions. Health professionals regard it as the gold‑ standard for diagnosis because of its effectiveness and efficiency. Traditional hysteroscopy systems, and the

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

This system involves the process of taking soil samples from a potential building site, mixes it with water and then the sedimentation process is evaluated by a camera and analysed to determine how much clay is in the soil sample. This in turn will then provide the engineers with information on what

This system provides accurate, digital, mid-upper arm measurements for screening of severe and acute malnutrition in children, as prescribed by the World Health Organisation (WHO). The system electronically captures the appropriate measurements and then proceeds to store and analyse the data using a

The digital infantometer provides accurate digital anthropometric measurement data for tracking the development of babies. The accurate measurement of weight, recumbent length and head circumference data are prescribed by the World Health Organisation (WHO) to assess the optimal growth of babies up

We have developed a universal, non-invasive remote condition monitoring system for ventilators. It provides remote monitoring of a heterogeneous/ multi-brand fleet of ventilators and patients’ respiratory function. In an already stretched healthcare system with limited human resources, this will

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
