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 Rotatable Fish Drying Frame is aimed at formalising a specific fish-drying process already used by different communities in Africa. The frame allows for the drying of up to 100 kg of fresh fish at a time using the existing iteration. The key principle is that after one week of drying the drum
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 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
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
This invention relates to a continuous solids/fluid contacting process and equipment in which appropriate solids are contacted with a fluid that may be either liquid or gaseous, or a combination thereof, under elevated pressure and optionally elevated or reduced temperature. More particularly, but
Omega Caro-E Xtra combines Omega-3 fatty acids with 11 different carotenoids and five different forms of vitamin E, all derived from Palm oil and manufactured by a patented process in Malaysia. It also contains 50% of the daily requirement for vitamin D. The concept was created and developed in
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
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
