Magnetic Fields and Manipulation of Water Behaviors: A Viable Method for Reducing RO Specific Energy Consumption
The use of magnetic fields to cause changes in the properties of aqueous media presents new opportunities for improving the performance of membrane systems. Many promising, and possibly paradigm shifting, […]
Key Parameters to Consider When Designing a Membrane Plant
The City of Brandon, Manitoba, along with CH2M (a wholly owned subsidiary of Jacobs Engineering Group), is currently completing the design for an upgrade to the City’s existing lime softening […]
Reverse Osmosis Membrane Compaction and Embossing at Ultra-High Pressure Operation
Herein, we evaluate the performance (i.e., flux and rejection) of commercially-available, thin film composite brackish water RO (BWRO), seawater RO (SWRO) and high-pressure RO (HPRO) membranes operating at pressures from […]
Managing and Treating PFAS in Membrane Concentrates
Per- and polyfluoroalkyl substances (PFAS) have detrimental impacts on human health and the environment. Reverse osmosis (RO) and nanofiltration (NF) have shown excellent PFAS separation performance in water treatment; however, […]
Best Practices for Start Up and Commissioning of New and Retrofitted Reverse Osmosis Facilities
Extensive instrumentation and controls logic are required for reverse osmosis (RO) facilities to function properly. Proper steps must be taken during start up and commissioning to assure that these systems […]
Reviewing the Options: Treatment Alternatives for Tempe’s Kyrene WRF
A comprehensive evaluation was performed to determine the most suitable treatment technologies and approach for plant improvements as part of recommissioning the KWRF, including the previous membrane bioreactor (MBR) process […]
122,000 M3/Day Into a 106,700 M3/Day Footprint – Seawater Desalination Expansion in Morocco
The OCP Group, founded in 1920, is a Moroccan state-owned phosphate rock miner, phosphoric acid manufacturer and phosphate fertilizer producer. OCP owns and operates a large seawater desalination facility at […]
A Plethora of Seawater Intakes Which Will Be Selected?
The Claude “Bud” Lewis Carlsbad Desalination Plant (CDP), pictured in Figure 1, has been operating for nearly 3 years, producing approximately 50= million gallons per day (MGD) to meet 10 […]
Demonstration of Artificial Intelligence and Machine Learning in Potable Reuse Projects
In many potable reuse projects, we largely rely on traditional control logics along with the conservative set points to take a unit process or entire treatment train offline to prevent […]
