WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  1. Pure Oxygen Injection Into A Pipeline
    9/15/2018

    The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

  2. Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings
    9/13/2018

    The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

  3. How Data And Nature Can Combine To Help Small Wastewater Treatment Plants Address Huge Hauling Costs
    9/13/2018

    It is no secret that the number of landfills has been steadily decreasing across the United States. As more and more cities adopt ‘zero waste to landfill’ sustainability goals, the number of landfills has shrunk from 6,326 in 1990 to 1,738 in 2015. Decreasing landfills has meant increased waste hauling costs for wastewater treatment plants (WWTPs) as sludge travels farther distances to reach landfills.

  4. Stokes' Law and How Inclined Plate Settlers (Lamellas) Work
    9/12/2018

    In this video, we discuss the curious science that is the inclined plate settler (also known as a Lamella). The process is a bit counter-intuitive, but through an interesting experiment, this video shows how they work. Inclined plate settlers can reduce required footprint by 80% compared to traditional gravity settling.

  5. FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey
    9/11/2018

    Despite the destruction of Hurricane Harvey in August 2017, Duperon® wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake® bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

  6. CAPITAL CONTROLS® Ozone Generator Video
    9/10/2018

    Ozone is used widely for water treatment in Europe and Asia. Now, with more than 40 years of global experience, De Nora is bringing CAPITAL CONTROLS Ozone to North America.

    A powerful oxidant with fast reaction time, no added chemicals, and reduced disinfection byproducts, Ozone is an appealing and growing option for water and wastewater treatment. Watch the full video to learn more.

  7. Harmful Algae: How To Stay Ahead Of The Bloom
    9/6/2018

    It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.

  8. Mitigating Environmental Impact Of Gold Mine’s Wastewater Through Ozone Oxidation And Aquifer Re-injection
    9/5/2018

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

  9. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints
    9/5/2018

    The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

  10. Crafting H2O — The Science And Art Of Beer Making
    9/4/2018

    Cincinnati-based MadTree Brewing Company is serious about how they make their beer. Their scientific approach means that they also pay close attention to the water they use, a message they’re more than happy to share.
