Trailblazer Technologies’ John Bewsey is pioneering cost effective and potentially profitable ways of processing neutralised acid mine drainage (AMD) water, industrial wastewater and even underground ‘brakwater’. In this article, he describes his KNeW (Potassium Nitrate ex Waste) process, which relies on scalable ion exchange CSTR batteries with some value adding regeneration and post regeneration twists to transform dissolved contaminants into valuable fertilisers and industrial salts.

Another R100-million investment in the FLSmidth Supercenter in Delmas, Mpumalanga, has set the South African facility up as the Group’s global centre of excellence for the manufacture and supply of vibrating equipment including dewatering screens and associated wear components and spares.
