Development of innovative hybrid technology for recycling wastewater from steel and metal pickling processes

Aim is to develop hybrid technology enabling treatment and subsequent reuse of WW originating from pickling processes of steel and other metals, which are characterized by high concentrations of nitrogen, fluorides and metal ions making them difficult to treat by conventional methods. Technology will be based on combination of precipitation methods and denitrification bioreactor supported by biomass carriers (nitrate reduction). Adapted denitrification consortia will be isolated and lyophilized, allowing their subsequent use in other systems. Technology will be placed in transport container and will be equipped with advanced control system, including online access. Since main recipient supplies pickling technologies all over the world, technology will be applied mainly in foreign markets.
