Wits researchers have developed a water treatment plant which removes organic pollutants from municipal bulk water. The process is environmentally friendly, making use of sunlight to purify water, thus saving energy and eliminating the need to use chemicals. Its modular design allows for scaling...

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...

The Technology Stations Programme (TSP) was established to enable Universities of Technology (UoT) to provide technology development services to small and medium enterprises (SMEs). The Technology Stations (TS) provide innovative Science, Engineering and Technology (SET) solutions for complex

The Technology Station in Chemicals (TSC) is situated at Mangosuthu University of Technology (MUT) in Umlazi. MUT provides technological support and promotes innovation for Small Medium Enterprises in the Manufacturing and Chemical sector.

Solvent extraction (SX) is one of the major separation and purification unit operations in hydrometallurgy. Its power lies in the highly selective solvents that are commercially available. Mixer-settlers and extraction columns are the conventional process configurations. In SX, the aqueous pregnant...
