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 […]
Design Criteria and Operating Conditions Have Sizeable Impacts on Trace Organic Removal by Reverse Osmosis for Potable Reuse
Water scarcity, which was thought to be a problem for the distant future, is fast becoming a reality in parts of the United States and the world. Climate change, coupled […]
Use of Advanced Three-Stage Membrane System for Turning Extreme Wastewater Into Boiler Feed Water
An engine manufacturer enacted a number of sustainability goals, one of which was 90% wastewater reuse. One facility in the northeast United States implemented a ceramic ultrafiltration system in 2019 […]
New Material Membranes and the Holy Grail: Chlorine Stable Reverse Osmosis Membranes
The increasing urgency of the water scarcity disaster that the world faces is broadening the application of new membrane technologies to more challenging water sources, but the notable absence of […]
Closed-Circuit High-Pressure Membrane Systems for the Separation of Per and Polyfluoroalkyl Substances
In this study, four commercially available membranes (NF270, NF90, CR100, and SW30) spanning the loose NF to tight RO separation ranges were investigated for their PFAS rejection performance. The specific […]
