Brunswick County’s LPRO NPDES Permitting Process
In 2017, Brunswick County government and it’s citizens were surprised to find high levels of PFAS in their drinking water. The public utility participated in piloting multiple removal technologies and […]
Tar Heels and Polyamide Reels: LPRO Piloting in the Old North State
This presentation will summarize three case studies of piloting low-pressure reverse osmosis (LPRO) for the removal of emerging contaminants, such as per- and polyfluoroalkyl substances (PFAS) and 1,4-dioxane. The speaker […]
A Pilot Study to Evaluate PFAS Removal from Filtered Water
This presentation will review the removal of per- and polyfluoroalkyl substances (PFAS) from surface water using nanofiltration (NF). A 20-gpm NF pilot has been in operation since October 2021 to […]
Tutorial: Reverse Osmosis Membrane Technologies for Purifying Water
Today’s membranes for reverse osmosis are primarily thin film composite constructions or porous asymmetric films that are rolled into modules for incorporation into water purification plants. The composite membranes are […]
Design Criteria and Operating Conditions Have Sizeable Impacts on Trace Organic Removal by Reverse Osmosis for Potable Reuse
This presentation describes the results of mathematical modeling that demonstrates the extent to which reverse osmosis design criteria and operating conditions affect the removal of trace organics in potable reuse […]
Rethinking Membrane Plant Operations
The City of Bozeman WTP has had membranes in service for 8 years. Over the course of the last 8 years plant operators have been working to optimize and improve […]
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, […]
Emerging Membrane Strategies to “Unstick” PFAS from WRFs
This presentation will explore the environmental fate and transport of PFAS compounds and examine multiple pre-treatment strategies at WRF’s to mitigate their infiltration into our water sources. In addition, implementation […]
The Maelstrom of Microplastics and Membrane Mitigation
Ian C. Watson Fellowship – 2022 Recipient
The American Membrane Technology Association (AMTA) is pleased to announce that the 2022 recipient of the Ian C. Watson Fellowship for Membrane Advancement is Mr. Christopher Hagglund of the University […]
