  1. Video: Getting Off The Water Grid, With Membranes 7/14/2023

    Membranes have long been proven effective for a variety of applications, but certain other applications pose difficulties for the technology, mostly due to O&M concerns. Next-generation membranes, however, have the ability to overcome traditional challenges — just in time to meet requirements for greater contaminant removal and sustainability.

  2. 10 Technologies And Breakthroughs From ACE16 7/14/2016

    This year's Annual Conference and Exposition (ACE16), held by the American Water Works Association (AWWA) from June 19 to 22, was the first following the tragedy of Flint — a time when the drinking water industry is under intense scrutiny.

  3. ED vs. RO: The Benefits Of Electrodialysis For Desalination 8/11/2015

    There is no doubt that reverse osmosis (RO) currently reigns among desalination techniques, if your metric is total number of installations. But a new competitor has arisen, at least for particular applications. If you have brackish water in the 2,000 to 15,000 ppm range of total dissolved solids (TDS), you may want to consider electrodialysis (ED) over RO.

  4. The Do’s And Don’ts Of MBR Pretreatment 5/5/2015

    They say a picture's worth a thousand words. If that's true, this image of a fouled membrane bioreactor (MBR) system needs little prelude — it's simply what happens when you don't properly protect your membranes with pretreatment.

  6. Will Dow’s Breakthrough Revolutionize Water Treatment? 2/12/2015

    A Q&A with Snehal Desai, global business director for Dow Water & Process Solutions, about the power of RO (reverse osmosis) membrane technology — to provide cleaner water, save precious resources, and improve sustainability.

  7. Top 10 Technologies From WEFTEC 10/23/2014

    They did it again. Seemingly every year WEFTEC breaks records for size and attendance, and 2014 in New Orleans was no exception. There was a lot to choose from, but I picked my favorite innovations to highlight in what has become another annual tradition — Water Online’s “Top 10” from WEFTEC.

  8. Radioactive Waste: Can Membranes Reduce The Fear Factor? 10/1/2014

    It’s no wonder that the word "radioactive" scares people. I remember Chernobyl. I was raised on The Simpsons, with its bumbling plant operators and three-eyed fish. I've followed the Fukushima tragedy closely. But, scary or not, nuclear power isn't going anywhere soon.

  9. Views From The Top: GE Water CEO On The Future Of Reuse 7/1/2014

    Speaking on the state of the challenging water/wastewater treatment market — hampered in recent years by slow municipal growth — Heiner Markhoff, a leading voice in the water treatment technology market, sees “light at the end of the tunnel.” Find out why in this exclusive Q&A with Water Online.

  10. Membrane Masters: Learning From The Best 5/23/2014

    After more than 50 years of development, it seems membrane technology is ready for liftoff.
