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....
MF/UF System Design
An overview of membrane system design concepts and methods, supported by experience with real-world projects....
Fifteen Years of Successful Low-Pressure Membrane Filtration of Surface Water in Tennessee - Lessons Learned
Fifteen years of successful operation of the DRUC low-pressure membrane facility have demonstrated that membrane filtration is clearly a normal, not novel process that can be cost effective and extremely reliable. Optimization of the process over the first few years of operation yielded significant power and chemical savings. Fouling trends demon...
MF/UF Membrane Service Life & Replacement in the Lake Michigan Region
As membrane technologies have evolved, ever increasing knowledge about municipal UF/MF membrane system use has been obtained to consider the reality of life cycle costs over 20 year periods. This presentation will focus on the membrane replacement and maintenance life of several Lake Michigan treatment technologies, each of which has a varying d...
Regulatory Comments on Membrane-Based Water Treatment
A presentation on membrane-based treatment by the regulatory agency in Wisconsin that is responsible for water treatment project oversite....
Developing and Implementing a Membrane Cleaning Procedure
My RO is producing water, when do I need to clean? How do I clean? This presentation will address the when and how of RO membrane cleaning. We will define the key indicators of when it is time to clean. We will outline the basic procedure to follow to return the membranes to normalized productivity....
Foulant Identification at Midwestern MF/UF Membrane Plants
This presentation focuses on the types of fouling that are currently being experienced at a variety of MF/UF membrane plants in the Midwest. The discussion includes how the foulant materials are setting up in the MF/UF membrane elements and how the autopsy process is being used to identify foulants and provide solutions for their removal. Several ...
South Milwaukee Water Utility: Past, Present and Future
As one of the oldest water filtration plants on the west shore of Lake Michigan, the South Milwaukee Water Utility has provided safe drinking water for residential and commercial customers for more than 100 years. When membrane filtration replaced conventional rapid sand filters, the Utility positioned itself to continue its proud history....
Manufacturer's Perspective on Designing MF/UF Systems for Specific Modules versus Open Platform
In the past 10 years, several MF and UF modules have become available to System Integrators from manufacturers who only sell MF/UF modules, much the same procurement model as for RO elements. This is a new business model compared to previously when the System Integrators had their own proprietary MF/UF membranes. The MF/UF systems using these 'non-...
Advantages of a Constant High Quality Feed Source: 14 Years of UF Membrane Operations
The Racine Water Utility implemented ultra-filtration membrane treatment in 2005. Piloting of 2 submerged membrane systems provided the basis for using full conventional surface water treatment prior to membrane filtration. This decision to provide high quality feed water to the membrane system has potentially extended membrane life, streamlined ...
Pretreatment Makes a Big Difference - Lessons Learned from Fargo Membrane WTP Start Up
The City of Fargo, ND recently started up a 15 MGD integrated (UF-RO) membrane water treatment plant (MWTP) in late 2018. The membrane WTP was designed a parallel treatment process to the City's existing 30 MGD Lime Softening/Ozone/Filter WTP. This presentation will give a project update along with discussion on challenges related to project star...
New Ultrafiltration Membranes at the City of Two Rivers, WI Drinking Water Plant Operate for Two Years with No Fiber Breaks
In early 2016, the City of Two Rivers, WI began looking at replacing the hollow-fiber ultrafiltration (UF) membranes at their 3.75 MGD drinking water plant. The UF system had been in operation since 2003/2004 and, since then, the membranes had been repaired often and replaced twice due to ongoing fiber breakage and air integrity test (AIT) failure...
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....
A "New" Water Source: Decades of Potable Water Reuse in California
Reuse in California has been a key part of the water supply for decades. The introduction of advanced treatment technologies such as microfiltration, reverse osmosis and ultraviolet light has allowed indirect potable reuse to thrive in the state. California's history of indirect potable reuse using membrane technolgies will be highlighted with pr...
Membrane Water Treatment Research Programs at the Bureau of Reclamation
The USBR conducts and/or sponsors a long list of water supply and treatment research programs, including many university and post-doc fellowships. USBR's membrane oriented research projects are described in the presentation....
