Lessons Learned from Two Membrane Applications on Wastewater Reuse

This paper discusses the lessons learned at the City of Fargo and the City of Grand Forks, North Dakota, water reuse facilities. A 1.4 MGD Effluent Reuse Facility (ERF) was constructed in the fall of 2008 to supply water to an ethanol plant. During the summer of 2014, a 4-month pilot study was performed to investigate an integrated membrane system that treats the City of Grand Forks WWTP secondary effluent and supplies high quality water to a proposed $2 billion nitrogen fertilizer plant.
