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 […]
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. […]
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 […]
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 […]
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 […]
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 […]
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 […]
Membrane Applications in the Midwest
This presentation will give a brief overview of RO technology and its application in midwest region with examples. The first example is Fargo membrane plant that has been recently constructed. […]
WaterOne’s Membrane Maintenance Practices
WaterOne has been using membrane filtration at its Wolcott Treatment Facility for almost 10 years. The membranes are still performing well with few problems. One reason for this is attention […]
Plant Design Considerations
Overview of and introduction to membrane plant design considerations for both microfiltration and ultrafiltration (MF/UF), i.e., low pressure filtration membranes, as well as for reverse osmosis and nanofiltration (RO/NF) membranes. […]
