Drinking Water Disinfection Podcasts

1. Microbial Contamination Monitoring For Water Distribution Systems 7/5/2017

   Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.

2. 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.

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. Replacing The Traditional Use Of Chlorine As A Disinfectant 10/29/2015

   Steve Day, Marketing and Product Management Director with Calgon Carbon UV Technologies sat down with Water Online Radio to talk about his company, and UV technology.

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. Will Peracetic Acid Replace Chlorine? 10/20/2015

   Chlorine has long been a water treatment staple, but it’s not without its complications. As an alternative, some treatment facilities have been turning to peracetic acid (PAA) and enjoying several key advantages.

7. Real-Time Data Solutions To Identify A Stubborn Disinfection Byproduct Threat 7/8/2019

   When it comes to trihalomethanes, the disinfection byproducts also known as THMs, a range of methods are available for their removal from water as well as avoiding their creation altogether. While sophisticated, those solutions offer little or no insight into the process. In this Water Talk interview, Rick Bacon, CEO of Aqua Metrology Systems, and Cliff Tormaschy, CEO of Medora Corp., discuss the use of real-time data to identify THM threats and diagnose critical treatment system performance.

8. 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.

9. The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried? 7/12/2018

   A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.

10. 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.
