Membrane basics are presented with a short review of high pressure and low pressure technology, membrane construction and properties. A few membrane related terms will be presented and a discussion of membrane systems will be given. This presentation is meant to be a basic primer for those not familiar with membrane treatment and a refresher cour...

The presentations will highlight key design concepts for MF/UF systems as well as considerations for intergating MF/UF systems into a water treatmentprocess train. The presentation will introduce the audience to flux selection, rack sizing, flow control concepts, CIP system design, and residuals handling considerations....

This presentation will present guidelines for good basic design parameters for membrane treatment systems including hydraulics and energy efficiency. Detailed information on component selection and materials of construction evaluation will be provided for the membrane process and related ancillary components such as cartridge filters, pumps, clean...

Membrane bioreactors (MBRs) are used in a wide variety of wastewater applications, including both municipal and industrial. MBRs are unique in that it consists of several subsystems that must work harmoniously together to ensure a successful operating system. The needs and requirements of a particular wastewater treatment project will drive the d...

Advancements in technology and manufacturing have brought reverse osmosis and nanofiltration membranes to the forefront in many of today's filtration processes. New technologies and applications promise to expand this role even futher. In this talk, we provide a perspective on the future challenges and applications for membrane filtration and the ...

This talk gives the perspective from a state regulator regarding reviewing plans and specifications for membrane technology. The talk will address the primary concerns of the regulator. It requires time and knowledge to review advanced technologies such as membrances and often the regulators are playing catch-up with the consultants and designers ...

In the past 8-10 years, MF and UF modules have become available to system integrators from membrane manufacturers who only sell modules, much the same sales process as for the RO elements. This is a new business model compared to previously when the system integrators had their own proprietary MF/UF membranes. This non-proprietary model has resulte...

Overview of the Columbia Heights Membrane Plant: The City of Minneapolis' drivers for its construction and brief overview of its first 12 years of operations....

The City of Highland Park, IL has recently completed implementation of a new 30 MGD submerged ultrafiltration membrane system into their existing drinking water treatment plant. Severe site constraints presented several challenges to the project and requried repurposing of many existing structures....

The City of Fargo, ND currently is constructing a 15 MGD integrated membrane water treatment plant (pretreatment, UF, & RO) slated to be finished in 2018. Prior to design, the City performed an extensive pilot program to prove out the membrane process for Sulfate removal as well as refine treatment process. This presentation will cover lessons le...

Many older proprietary microfiltration and ultrafiltration (MF/UF) membrane systems have been in service long enough to require replacement of elements. This paper presents methods to specify and select new replacement elements for existing proprietary systems allowing competitive bids between suitable manufacturers (rather than risking higher cost...

Optimizing membrane performance has always involved looking at operations, system design, and process design as part of a typical troubleshooting approach. There are significant advancements in the realm of system diganostics and membrane perfomance analysis that further ensure an accurate and reliable outcome. This presentation will review some of...

Will break into two groups to have hands on activity regarding Investigating Hollow Fiber UF and Spiral RO/NF Construction and what it means to Operators....

The use of membrane technology for the production of drinking water is becoming more commonplace and more cost-effective every year. Many utilities are converting to membrane filtration to help fortify their facilities for current or future regulations. The author has been fortunate to at the front lines of the membrane wave in Ohio - having part...

With the latest advances in ceramic ultrafiltration (UF) membrane manufacturing the capital costs are now competitive to polymeric UF membranes. The presentation will review performance data of the latest ceramic UF membranes in installations and pilot trials treating backwash water recovery and secondary effluent for reuse. The data highlights th...

The presentation will give an introduction to when the El Paso Water Brackish Water Desalination Plant was built and what lessons have been learned the past 10 years. It will talk about pilot testing, design flaws to the plant, changes that have been made to improve the operation and maintenance of the plant. The presentation will discuss the RO ...
