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 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

The technology relates to a new generation of telecommunications and data processing technology with improved wavelength sensitivity in the visible and near-infrared wavelengths range rather than microwave communication in 2–4 GHz. The technology provides the realisation of optical sources (LEDs)
