The City of Fargo Water Treatment Plant (WTP) recently piloted GE submerged ZeeWeed 1000, Siemens encased MemCor L20N, and Pall encased UNA-620A membranes for its new 15 million gallons per day (mgd) membrane WTP. The source water Sheyenne River quality is challenging for membrane treatment: elevated total dissolved salts, high total organic conten...

City of Fargo North Dakota has a surface water reverse osmosis system (RO) which requires brine concentrate discharge management back to a river that meets NPDES permit requirements. Contaminants of concerns are sulfates and heavy metals. Model simulations performed to determine proper mixing zone....

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 ...

Fargo owns and operates a15 MGD membrane water treatment plant built in 2018, the first true surface water RO plant in the nation. The treatment processes consist of coagulation/flocculation/sedimentation, UF membrane, and RO membrane. The RO bypass flow goes through ozone and GAC. This presentation will discuss some unique aspects of the project t...

This presentation will provide an overview of Fargo Water Treatment Plant (WTP). In 2019, Fargo completed the construction and startup of a new 15-MGD Membrane WTP (MWTP). The MWTP employs Ultrafiltration (UF) and Reverse Osmosis (RO) to help treat two different water sources that are typical high in total hardness and total dissolved solids (TDS)....
