Wastewater Contaminant Removal Podcasts

  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 Holistic Approach To Water Treatment
    10/21/2019

    Not all water is the same, so don't be sold on a "one-size-fits-all" solution. Many treatment providers will attempt to fit a square peg in a round hole, while others — a select few, in fact — can provide a fit-for-purpose solution based on broad, customized capabilities. That's the pitch from U.S. Water Services, which recently became part of Japan-based Kurita Water Industries, a resource- and technology-rich company with global reach.

  3. Forward-Looking Technology Anticipates Compliance Needs
    10/19/2019

    When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address the growing concern over chlorate disinfection byproducts (DBPs) in drinking water. For example, De Nora’s new ClorTec Gen III onsite hypochlorite generators generate up to 3,000 lbs./day of chlorine-based disinfectants while reducing chlorate formation and cutting operating costs by 15 percent as compared to previously available models.

  4. An Improved Approach To Turnkey Disinfection Solutions

    Engineered skid systems provide a compact configuration chemical feed at water and wastewater treatment plants. While these all-in-one metering pump solutions bring tremendous value to their users, traditional platforms have their pitfalls.

  5. Capacitive Deionization Takes Off
    11/26/2018

    Capacitive deionization (CDI), sometimes called electrochemical demineralization, is referred to as Radial Deionization (RDI) by Atlantis Technologies, which has developed a proprietary form of the process. If you haven't heard of it by any name, or would like to know more about its considerable treatment capabilities, tune into this interview with Patrick Curran,

  6. The Expanding Role Of Ozone
    10/30/2018

    As water reuse becomes increasingly common, more utilities will get to know ozone. To explain its role in water treatment schemes, Water Talk welcomed Jim Lauria, Vice President of Sales and Marketing at Mazzei Injector Company, and Ben Kuhnel, Senior Project Manager for Arcadis. Learn how ozone works in concert with other processes to safely recycle water and treat contaminants of emerging concern — even in mobile/on-site applications.

  7. 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.

  8. 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.”

  9. Getting Chlorine Disinfection Right
    11/1/2017

    Of all the process considerations facing wastewater treatment operators, disinfection is one of the most important. In this exclusive Water Talk interview, Gary Lohse, Technical Sales Manager, Disinfection with De Nora Water Technologies, discusses how disinfection has become increasingly complex over time. Lohse reviews a host of selection criteria including target microorganisms, control strategies, disinfection by-products, capex and safety.

  10. Drumming Up Chemical Injection
    10/24/2017

    The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”
