This study investigated the treatment of an aerated groundwater using membrane technology. The raw groundwater contained elevated levels of sulfate and natural organic matter (NOM) which often pose challenges to membrane systems. The study includes pilot testing results of hollow-fiber and nanofiltration membranes designed to offer NF removal properties using lower power consumption. Water quality was monitored during the course of the study to assess membrane rejection with regards to sulfate, organics, and turbidity removal. Hydraulic parameters including flux, specific flux, and transmembrane pressure were monitored continuously throughout the pilot testing period to determine membrane performance and fouling potential. Pilot performance was assessed at multiple operating pressures and flux settings to confirm process sustainability under a number of different scenarios.
