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

This technology involves a method for generating hydrogen in an electrolysis cell. A proton exchange membrane (PEM) is used to separate anode and cathode chambers of the cell. The space between the anode and the PEM is filled with aqueous sulfuric acid. In use, gaseous sulphur dioxide is fed to the

This process is used for generating hydrogen by providing a hydrogen chemical carrier in the presence of an active catalyst in a reactor vessel and elevating the temperature inside the reactor by electromagnetic process to allow a dehydrogenation reaction to generate hydrogen. The active catalyst is

The invention relates to a low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate-velocity wind and generate electricity efficiently for household use. Current large-scale wind turbines in South Africa are located far field and the energy generated must be transported

The technology relates to an upright tubular fixed-bed reactor body comprising a heat -dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Ficher-Tropsch, which are prone to heat build-up. The heat pipe is

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

This novel system allows for digital monitoring of payloads on heavy vehicles and avoids repetitive, physical weighing of compliant vehicles at static weighbridges to check overloading status. This is achieved by digitally linking all weighbridges and existing or new cameras on a specific corridor

LeguPro is a protein-rich pasta, which is produced from non-traditional pasta ingredients such as peanuts, soybeans, and chickpeas. It is a cost-effective nutrient-dense high protein, healthy instant noodle product and aims to give consumers an alternative staple food product to be consumed as is or

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 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
