Drinking Water Disinfection Podcasts

1. Understanding The Benefits Of Chlorination 10/4/2013

   Fletcher Roche, Product Manager at Evoqua Water Technologies, explains why chlorine gas is a safe and cost-effective disinfection solution.

2. Is UV Poised For Increased Adoption? 7/23/2014

   Disinfection can be achieved through chlorine, membranes, ozonation, or UV (among others), but the latter may be best equipped to serve the changing water treatment market.

3. 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.

4. New Trends In Mixing Technology For Water And Wastewater 7/9/2019

   Polymers used in wastewater treatment represent one of the most expensive operating costs for municipalities. By providing an optimal environment for the activation of these polymers, plants can improve efficiency by as much as 20 percent or more. At the same time, drinking water plant managers face enormous pressure to control the disinfection residual. In this Water Talk interview, Matt Boeh, director of sales for UGSI Chemical Feed, discusses the advanced mixing technologies that can be used to improve polymer usage as well as address drinking water quality issues in distribution systems.

5. New STEPs Minimize Biosolids, Energy, And Installation Costs 10/18/2019

   When low population density and troublesome topography make traditional gravity sewers cost-prohibitive, septic-tank effluent-pumping (STEP) technology offers an affordable alternative. In this Water Talk discussion, Mike Saunders, market segment leader for engineered systems at Orenco Systems, outlines how to match the right technology to the need. Orenco’s new decentralized liquid-only sewer systems treat septic effluent that is reduced by about 80 percent of its strength. Its smaller-diameter pressure mains run for 10 miles without supplemental pumps and install at just a fraction of the depth of traditional sewers. The approach minimizes biosolids, runs on little pumping power, and requires no blowers, so it minimizes energy requirements and keeps both installation and maintenance costs lower than those of conventional sewer systems.

6. The Value Of Wastewater: Closed Vessel UV Disinfection For Water Reuse 11/8/2013

   Jon McClean, President of Engineered Treatment Systems (ETS), explains how UV disinfection of wastewater provides an effective and sustainable solution to growing water shortages.

7. Helping Chlorine Out During The Disinfection Process 7/26/2016

   If you’re still unfamiliar with the name De Nora, it’s time to get acquainted. Traditionally a supplier of plates for electrolytic industries, the company purchased Severn Trent’s equipment business in 2015 and is investing in its core business of disinfection and filtration.

8. 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.”

9. Safer Disinfection With Peracetic Acid 1/10/2014

   John Maziuk, Technical Development Manager at Solvay Chemicals, discusses the benefits of peracetic acid over other wastewater and stormwater disinfection methods, including no harmful byproducts, a simpler process, and a longer shelf life.

10. An Improved Approach To Turnkey Disinfection Solutions 10/18/2019

    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.
