Evaluation of optimal reuse system for hydrofluoric acid wastewater

► Coagulation and ion exchange technologies were ineffective in removing fluoride. ► Polyamide RO was more efficacious than cellulose RO due to its high flux and rejection. ► Spiral wound RO system was more preferential to disc tube RO system for reusing raw hydrofluoric acid wastewater. ► Combined...
