    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.

    Satisfying LCR Compliance Measurement And Management

    The challenges of complying with the Lead and Copper Rule (LCR) and other emerging regulations in a post-Flint world are high-priority for a variety of organizations — from government agencies, to public water systems, to individual facilities such as schools. This Water Talk discussion with Megan Glover of 120 Water Audit addresses the scope and execution of those challenges. It covers everything from providing point-of-use testing kits for sampling individual water spigots to managing overall Safe Drinking Water Act and LCR compliance through cloud-based software. Most important, it gives context to practical solutions for the many utilities and facilities coping with some level of lead exceedance.

  • Total Dissolved Solids: A Matter Of More Than Just Good Taste
    Total Dissolved Solids: A Matter Of More Than Just Good Taste

    Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.

  • Minimum Liquid Discharge – The Best Bang For Your Buck
    Minimum Liquid Discharge – The Best Bang For Your Buck

    Fresh water sources around the globe are becoming increasingly stressed due to population growth, industry use, and changing climate patterns.  These stresses drive the need to make the most out of every drop of water available.  Water treatment systems inherently produce a waste stream that contains contaminants removed during the treatment process.  This waste stream can often constitute 20-30% of the total water fed to the treatment system, representing a significant loss of a precious resource both in human and economic terms.  Minimizing this waste stream is a key part of the solution to solving the water crisis for both industry and people.

    How To Improve Test Accuracy With The Latest Sampling Technology

    Sampling and laboratory testing are major responsibilities for water professionals. Test results are used for process control, and ultimately to determine that water is safe for drinking, reuse, or discharge to the environment. Regulatory agencies rely on reported results for proof of permit compliance. So, obtaining representative, properly collected and preserved samples is the first critical step to ensure accurate test results.

  • Understanding The Probability Of Detection In X-Ray Inspection For Food Manufacturers
    Understanding The Probability Of Detection In X-Ray Inspection For Food Manufacturers

    Probability of detection (POD) seems like a relatively simple number which vendors use to reassure potential customers of a machine’s capabilities for contaminant detection. However, there is more to the numeric value of POD than just taking it for face value. This white paper explains how POD is calculated and why 100% POD is unachievable and it also looks at factors that affect sensitivity of contamination detection while lastly discussing how the latest innovations in x-ray inspection technology are designed to enhance detection performance, while explaining how food processors can ensure POD is consistent throughout the lifetime of their x-ray system.

    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.
