  • Filtering Out Failures: A Productive Conversion Experience For A Steel Mill

    Water filtration in steel manufacturing should be one of those things that mill owners never have to worry about. But when filter systems fail to perform as expected, it’s time to invest in a smarter design. That was the situation at a midwestern steel mill that embarked on a major, eight-year conversion of its water filtration infrastructure.

  • De Nora To Launch Visual Assistance Platform For Remote Customer Support

  • Forward-Looking Technology Anticipates Compliance Needs

    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.

  • De Nora's New Direction

    There is a lot to be excited about at De Nora lately. The recent acquisitions of two new companies is just part of the story, told in this video by Mirka Wilderer, CEO of De Nora Water Technologies. Wilderer is key to the wave of developments, as she only recently took the CEO mantle. Along with an introduction, this video from WEFTEC 2019 offers insight into trends and challenges facing the water/wastewater industry, including the most problematic contaminants and the ongoing struggle to update infrastructure. Potential solutions, as well as the roadblocks and drivers that can impact industry progress, are also identified.

  • De Nora Inaugurates New $29M Manufacturing Plant In Mentor, Ohio

    De Nora, multinational leader of electrochemical technologies and water treatment solutions, recently announces the opening of a greenfield manufacturing facility for the production of electrodes in Mentor, Ohio.

  • De Nora To Launch High Efficiency Electrochlorination System At WEFTEC 2019

    Global leader of sustainable technologies, De Nora today announces the launch of its next generation of ClorTec® on-site sodium hypochlorite generators at WEFTEC, the Water Quality Event in Chicago this month. The new high efficiency ClorTec® Gen III system uses an optimized electrochlorination process that reduces salt and power consumption to deliver a 15 percent operating cost savings over the previous ClorTec® DN Gen II system that was launched last year at WEFTEC 2018.

  • What You Need To Know About Mixed Oxidant Solution

    The main component of mixed oxidant solution (MOS) is chlorine and its derivatives hypochlorite and hypochlorous acid (ClO−, HClO). It also contains trace amounts of other chlor-oxygen species which work synergistically with the hypochlorite/hypochlorous acid to improve efficacy and performance. MOS is made from brine (salt) and energy, and is used for disinfecting, sanitizing and reducing the risk of infection due to pathogenic microorganisms in water and in other applications. It is particularly useful for customers who have specific challenges such as controlling biofilm or reducing disinfection byproducts exacerbated by biofilms.

  • Evaluating Bulk Hypochlorite Versus Hypochlorite Generated On Site

    Chlorine gas is the historical disinfection choice for municipal potable water and wastewater systems due to its low cost and ease of maintenance. However, the hazardous status of chlorine gas and its potential as a terrorist target are driving many facilities to consider alternative disinfection methods. The decision frequently comes down to a choice between commercial sodium hypochlorite delivered in bulk (hypo) and hypochlorite generated on site (OSG). The primary decision factors are safety, cost, ease of maintenance, and environmental impact.

  • Chlorate DBPs: Future-Proofing Water Disinfection For Chlorate Regulation

    Chlorate is a highly oxidized form of chlorine that can be introduced to a water source as an industrial or agricultural contaminant or into a finished water as a disinfection byproduct (DBP). As a DBP, chlorate can result from water disinfection with bulk sodium hypochlorite, chlorine dioxide, or hypochlorite formed through electrochlorination (EC) systems.
