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

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

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

This invention relates to a continuous solids/fluid contacting process and equipment in which appropriate solids are contacted with a fluid that may be either liquid or gaseous, or a combination thereof, under elevated pressure and optionally elevated or reduced temperature. More particularly, but

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
