Membrane Design and Troubleshooting Basics: MF/UF
There will be a review of MF and UF membrane products in the market and how they are used. This will include an overview of Preventative Maintenance, Troubleshooting, Module Maintenance, and Module Replacement. A knowledge of how, when and why MF/UF foul and a set of good maintenance procedures, membrane modules can be quickly repaired […]
Membrane Autopsy and Foulant Analyses
Autopsy is a qualitative and quantitative destructive analysis of a membrane element. It is often used to troubleshoot system performance issues and improve operations by analyzing foulant for a smarter CIP specialty chemical choice.
Fort Dodge Reverse Osmosis Water Treatment Plant Case Study
Fort Dodge Reverse Osmosis Facility is a newly started (April 2021) membrane treatment system in the state of Iowa. The presentation includes the initial reasons for the facility upgrade and why RO was chosen. Basic overview of initial pilot studies (2 in this instance, direct feed v pretreatment), current overall facility flow and treatment. Key […]
Grimes Reverse Osmosis Water Plant
New 3.5 MGD reverse osmosis plant introduction and overview. Experiences of starting up a new reverse osmosis plant including the trains themselves, chemical feed systems, pumps for distribution, and overall building systems. Grimes need for more water production was the reason for the new, larger reverse osmosis plant. Remodeled 1.4 MGD lime softening plant for […]
Understanding Salt Rejection the Path to a Healthy Membrane Life
This presentation is all about membrane rejection, how to calculate it, where to sample for it, and what the numbers are telling us. Knowing how to collect and analyze this information on a RO membrane system will allow an operator to setup a conductivity profile and then a rejection profile for all parts of the […]
Town of Walkersville, Maryland Integrated Membrane Water Treatment Plant
The ground water wells in town of walkersville were known to be under the influence of surface water. In 1999, a rupture in a sewer line caused over a million gallons of raw sewage into the Town’s well aquifer, causing plant shutdown, boil water notices, and pumping raw water to the sewer system for weeks. […]
Mid-West Membrane Projects: Lessons Learned from Pilot Study and Full-Scale Start-Ups
Learn about some common and not so common trials and tribulations of conducting RO/NF pilot studies and starting up full-scale RO/NF water treatment plants. The RO/NF process and the science behind it doesn’t change, but every project is unique in design as far as size, feed water source, pretreatment, piping arrangement, instrumentation, etc. which can […]
Pilot Study and Full-Scale Implementation of Greensand Filtration & Reverse Osmosis at Prestage Foods
This presentation covers the pilot study or iron removal filtration followed by reverse osmosis and the subsequent full scale system design and implementation at Prestage Foods in Eagle Grove, Iowa. This treatment system was to provide all site water requirements for the new Prestage pork processing facility. The challenges with iron removal and fouling of […]
Options for Expanding the Des Moines Saylorville Membrane Filtration Plant
This case study will describe the options considered for capacity expansion of Saylorville WTP in Des Moines, IA. The facility currently has submerged MF/UF filtration with a side stream RO system for softening. The alternatives analysis used a decision matrix which included capital and life cycle cost as well as non-economic factors to recommend long […]
Ceramic Pilot Testing for Potential Use in a 10+ Year Old Polymeric Membrane Plant
The Mandaree WTP has been using pressure UF membranes for 10+ years. As the modules reach the end of their life, and in consideration of increased plant capacity a ceramic membrane pilot was completed. This presentation will present the results of the pilot study.
