Membrane Processes
The presenations will provide a background on membrane processes for water treatment including RO, NF, MF and UF along with basic terminology and key points....
Reverse Osmosis and Membrane Softening
This presentation will provide data specific to the mid-west on water treatment considerations and benefits when evaluationg reverse osmosis or membrane softening. Water supply, pilot study, pretreatment, process design, operation and maintenance and data collection will be addressed....
Use of High Rate Lime Softening Followed by UF Membranes
This presentation will focus on the use of high rate lime softening process followed by UF membrane filtration. Two plants use surface water, while a thrid uses a groundwater source. The presentation will provide information on why this treatment process was chosen, design considerations, contruction and start up, and operational information....
Update on Fargo Membrane Water Treatment Plant
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...
Placement and Optimization of Pumps and Energy Recovery Devices in Membrane Systems
This presentation will consider how selection and placement of pumps and energy recovery devices can optimize membrane systems for capital or life cycle cost. The effect of interstage boosting using pumps and/or turbochargers on feed velocity, flux distribution, and energy demand will be discussed with an emphasis on device selection to achieve pr...
Experiences at Grand Forks and Regional Facilities on Operations and Troubleshooting
Summary of unique, pilot, design, and operations for three regional facilities including Grand Forks, Hillsboro, and Traill (and Valley City). All of which have RO, with Grand Forks and Valley City including UF. Topics may include organics passing through membranes and fouling, antiscalant tricks to reduce catridge filter, membrane replacement st...
Troubleshooting Membrane Systems
Water source changes, temperature change, cleaning protocol, mechanical failures are a few of the causes that effect production and membrane life. We will look at these different components and processes of membrane systems and how to troubleshoot them. We will also look at some real life examples and how the troubleshooting process took place....
Surface Water MF/NF Learnings
The Pembina Valley Water Coop is owned by 14 municipalities and operates three membrane treatment plants treating surface water. The presentation will discuss the key learnings from facilities operating low pressure and high pressure membrane systems along with a brief review of the facilities....
