Wastewater Disinfection Podcasts

  1. 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.

  2. 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.”

  3. 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.

  4. 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.”

  5. Decentralization Grows With Worldwide Property Development Expansion
    10/24/2017

    One of the trends in water and wastewater treatment over the past decade has been a growing demand for decentralized systems. Water Talk recently caught up with Nii Mensah, General Manager of Fluence USA, to learn more about the solutions that the new company (formed by the merger of RWL Water and Emefcy) is bringing to market to address communities’ treatment needs

  6. Converting Wastewater Treatment Facilities Into Botanical Gardens
    10/24/2017

    Municipal wastewater treatment has traditionally taken place as far away from the populace as possible. But as people flock to cities and encroach ever closer on these facilities, the practice of extending ever further out becomes impractical and expensive. And as water becomes scarcer, cities the world over are looking at recycling wastewater from their citizenry closer to home.

  7. Peracetic Acid (PAA) Disinfection Is Up For The Challenge
    10/20/2017

    The primary consideration for evaluating disinfection alternatives has to be permit compliance. But as Sarah Stewart, Associate and Senior Project Manager with CDM Smith explains in this Water Talk interview, contact time, high color, nitrates, industrial loads and many other factors all play a role in selecting the most practical and cost effect disinfection solution for your facility.

  8. Different Wastewaters Require Different Decentralized Solutions
    10/20/2017

    When we think decentralization, we often think of smaller and smaller systems, supporting a single-family home or business. So it was interesting to sit down with Bob Rebori, President of Bio-Microbics recently and learn that the Company is being asked to build larger decentralized systems to support a variety of commercial applications.

  9. Polymer Activation And Onsite Hypochlorite Generation
    11/3/2016

    Polymer activation through proper hydration of the polymer particle is critical in water clarification or sludge dewatering applications. According to Jeff Rhodes, Vice President of Commercial Development for UGSI Solutions, “the key is to have a high energy zone at the moment of initial welding, when the polymer and the water come together.”

  10. PAA And UV Pair Up To Improve Disinfection Performance
    10/26/2016

    Peracetic acid (PAA)-based disinfection is growing in the US, both as a standalone disinfection method and in conjunction with other applications such as UV. Water Online Radio sat down with John Maziuk, Technical Development Manager with Solvay Chemicals to understand why.
