    Chattanooga Engineers Club Monthly Meeting

    Monday, March 8, 2021

    12:00 noon

     

    “Scenic City Says Sayonara to Chlorine Gas”

    Tennessee American Water Company’s Citico WTP Conversion to Liquid Sodium Hypochlorite


    Speakers:

    Tyler Cross, P.E., Tennessee American Water Company 

    Justin Bolender, P.E., HDR Engineering, Inc.

     

    Tennessee American Water Company (TAWC) owns and operates the Citico Water Treatment Plant (WTP) on the south bank of the Tennessee River in Chattanooga, Tennessee. This plant is the largest source of potable water supply in the metropolitan Chattanooga area.  The plant previously used chlorine gas as a pre-treatment chemical and post-treatment disinfection agent at the plant. This presentation will highlight the planning, design and construction of TAWC’s conversion to disinfection with bulk storage liquid sodium hypochlorite.  As this project was put into service in late 2019, the discussion will not only speak from the experience of the design and construction phases, but also provide lessons learned based on operation of the facility for over a year. 

     

    The new disinfection facility includes four 10,000-gallon liquid sodium hypochlorite tanks which allows a 15-day supply for disinfection of the pre-treatment chemical and post-treatment disinfection for the 65 MGD WTP.  The new building includes a storage tank room with secondary containment, separate chemical feed pump and electrical rooms, heating, ventilation, fire protection and security components.  The roof of the building is designed such that the Fiberglass Reinforced Plastic (FRP) tanks can be replaced in the future by lifting the tanks through removable skylight openings.  The chemical feed system includes nine separate peristaltic pumps with independent piping systems to feed each chemical feed point.

    Chattanooga Engineers Club 

    A joint meeting with ASME and ASQ Chattanooga Sections

    Monday, March 22, 12 noon

    The Department of Energy’s Oak Ridge National Laboratory is home to one-of-a-kind scientific research facilities and hosts a spectrum of visitors, including those from the research community, industry partners, and college and K-12 students. In an average year, thousands of people tour the lab.

    In 2020, after in-person tours were suspended, ORNL added virtual scientist visits to virtual tours.  The site tours include multiple views to show floor plans, rotating interior views and 360-degree navigation.

    Our tour guide and presenter will be Jeff Cornett, Manager of Industrial Partnership and Economic Development.  Jeff will take us through three (or two) operations depending on time.

    ·  Manufacturing Demonstration Facility: Inside this DOE Office of Energy Efficiency and Renewable Energy user facility, see machine tooling in action and the large-scale additive manufacturing system that made the 3D-printed Shelby Cobra. Learn how researchers are advancing real time characterization to produce perfect parts and view MedUSA, a hybrid manufacturing machine.

    ·  National Transportation Research Center: At this DOE Office of Energy Efficiency and Renewable Energy user facility, learn how wireless charging technology and sophisticated power electronics are developed and evaluated. See a variety of engines used in research to evaluate new fuels, reduce emissions, and maximize fuel efficiency, as well as research platforms for advancing connected and automated vehicle technologies.

    ·  Spallation Neutron Source: Explore three floors of this DOE Office of Science user facility filled with state-of-the-art instruments dedicated to neutron scattering experiments. The accelerator-based system delivers proton pulses to a steel target filled with liquid mercury through a process called spallation. Those neutrons are then directed toward instruments that provide a variety of capabilities to researchers across a broad range of disciplines including physics, chemistry, biology, and materials science.

    You are in for a very special treat!

    Please register in advance for this meeting.

    After registering, you will receive a confirmation email containing information about joining the meeting.
