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 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 is still lagging. This invention exhibits advantages over the

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 the removal of crude oil from water bodies, these techniques are either focused on dissolving the spilled oil

The invention is a leakage detection system for water pipelines installed in partially saturated soils. Most soils in South Africa and the rest of Africa are partially saturated because the water table is usually deep. Given the large amount of water lost from water distribution systems worldwide

The invention The invention uses plastic waste and Waste Foundry Sand (WFS) to produce building and construction material with a density of between 1700 and 1750 kg/m 3 . The plastic is melted and WFS is used to produce a paste for the moulding of building material. Problem solved Plastics are vital

Using a metallurgical waste product, the invention consists of a method to treat acidic water from mining sites. The treated water can be used for industrial applications or, with additional steps, be treated for potable usage. Water is currently a scarce resource in South Africa, and the depletion
