  1. New RO And Other Techniques Lead To Improved Performance
    10/29/2019

    For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.

  2. A Modern Approach To Sewer Overflows
    10/7/2019

    As storm activity continues to grow, utilities are under increasing pressure to mitigate sewer overflows. Building enough storage to handle the excess runoff until it can be treated is no longer practical — in most places, it’s not even feasible to create a large enough space — and the issue will only get worse as storms continue to intensify. Meanwhile, most settling technologies that address overflows require chemicals and a complex process to start up, shut down, and store through off-peak times.

  3. Filtration For A New Era
    11/26/2018

    Filtration has been around for a long, long time, so it may be that most treatment plant operators feel pretty informed about its capabilities. But hearing from Brian Frewerd, Director of Application Engineering with Parkson Corporation and Water Talk guest, will likely prove enlightening. Frewerd provides background on sand filtration for tertiary treatment applications, followed by insight on notable technology improvements and performance milestones

  4. A Fresh Look At Membrane Bioreactors
    10/23/2018

    Membrane bioreactors (MBRs) are not new, but they are the subject of renewed interest among utilities, and for Carollo Engineers Vice President Andrew Gilmore. He sat down with Water Talk's Todd Schnick and Kevin Westerling to discuss the MBR renaissance and the reason for their rise in popularity.

  5. From Australia To California, Log Reduction Credits For MBR Systems
    7/10/2018

    Jon Loveland, Global Practice Leader - Alternative Water Supply at Black & Veatch, shares insight on a major development for membrane bioreactor (MBR) systems and potable reuse.

  6. Ozonia M and FiltraFast Provide New Options For Treatment Facilities
    11/20/2017

    If you don’t need the performance of an ultrafiltration membrane but also want to avoid the large footprint of a conventional media filter, you might want to consider FiltraFast extreme rate compressible media filters. As Ryan Hess, Director of Advanced Separation with SUEZ Water Technologies suggests in this Water Talk interview, “They provide roughly ten times the hydraulic loading rate of conventional media filters.”

  7. New Tools For Improving Membrane Bioreactors
    10/25/2017

    Toray Membrane USA introduced an aptly-named product at WEFTEC 2017, the NHP (New High Performance) module for membrane bioreactors (MBRs). Toray's Peter Waldron sat down with Water Online to discuss how the NHP, which features thin membrane flat sheets densely packed into easily interchangeable cassettes, differs from current industry offerings and how these features benefit MBR operation.

  8. De Nora Doubles Down On Innovation
    12/14/2016

    With 29 locations, 1,600 employees and research facilities in Japan, Italy and the United States, DeNora is one of the largest disinfection and filtration companies in the world. As Gary Lohse, Regional Sales Manager for De Nora, explains in this Water Online Radio interview, the acquisition of the former Severn Trent manufacturing division coupled with De Nora’s product innovation strength is driving enhancements to some of the most respected brands in the water industry.

  9. Selecting The Right Membrane For The Job
    11/30/2016

    In this Water Online Radio exclusive interview, Fred Wiesler, Global Director of Sales for the QUA Group, discusses some of the company’s key products, including the EnviQ that uses a flat sheet PVDF membrane, and has a .04-micron pore size. It provides ultrafiltration quality water, with the strength of a PVDF flat sheet membrane.

  10. Decentralized Membrane Treatment Technology
    11/7/2016

    In the early 90s, Bio-Microbics introduced membrane treatment technology, traditionally used in drinking water treatment plants, to the decentralized treatment market. In this Water Online Radio interview, Jennifer Cisneros, Director of Marketing for Bio-Microbics and Chair of the National Onsite Wastewater Recycling Association’s Marketing Committee, discusses the use of the onsite technology at an oyster bar where Total Kjeldahl Nitrogen (TKN) was about three times the level of ammonia.
