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...
