Fly ash is a waste by-product generated by coal-fired electricity power stations. Due to its environmental impact, there is a growing need for safe and sustainable methods of fly ash disposal. One effective approach is the beneficiation of fly ash through the production of zeolites—a class of
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
This technology utilises a microchannel reactor for the decomposition of ammonia, comprising two chambers: one for exothermic combustion of ammonia to generate heat. A second chamber of the reactor with a second catalyst receives a second stream of ammonia to provide endothermic decomposition of the
The North-West University (NWU) has developed and patented a method for producing hydrogen via hydrolysis, using an activated aluminium compound. Technology Benefits: Aluminum also can be recycled after the hydrogen production process. Hydrogen can be produced under high pressure. By-products are
The Vapour-Based Passive Multistage Solar Desalination System offers a sustainable and efficient solution for desalinating water using solar energy. The system is designed to operate off-grid, utilizing solar heat to drive the desalination process, making it ideal for remote areas where access to

A novel bioreactor system that uses membranes to create a compartmentalised system where two or more species can be co-cultured without mixing of species, while ensuring rapid exchange of metabolites and proteins between compartments and shared medium composition. The system operates continuously
The CSIR has established a bioconversion platform that focuses on alternative pathways for chemical production. The platform is geared towards local production and replacing imports of bio-based platform chemicals, including lactic acid. This shift will have a direct impact on the bioeconomy. The

The Cleancolytic Reactor System developed at the Cape Peninsula University of Technology is a one-step waste water treatment system consisting of highly reactive nanoparticles immobilized in a specialised reactor system for the purpose of treating industrial wastewater. The system utilizes a

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

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 the use of maghemite nanoparticles at pH < 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In a conventional way of AMD treatment, these pollutants are only removed at higher pH and requires costly alkaline chemicals

A method and apparatus for treating a fluid utilising nanoscience. The impurities in the fluid are trapped by the charged nanoparticles. The fluid is contained in a reactor that includes a moving magnetic system. When the reactor is in use, the moving magnetic system excites the charged
