Drinking Water Analysis Case Studies

  1. Installing Granular Activated Carbon Today To Prevent Regulatory Issues In The Future
    4/25/2019

    In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).

  2. Alaska WTP Takes Control Of Water Quality With UV254

    With the ongoing concern about water quality in Alaska, Philip Downing, the Remote Maintenance Worker for South East Alaska Regional Health Consortium, offered a new approach to a plant’s ability to continuously monitor and adjust treatment processes in response to changes in raw water quality.

  3. Rapid Microbial Assessment Following A Case Of Legionellosis
    12/3/2018

    A case of legionellosis an illness acquired from Legionella bacteria, which can grow in cooling water and potable water systems was diagnosed at a medical retirement home.

  4. Troubleshooting A Sudden Fecal Coliform Non-Compliance Event
    11/26/2018

    A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.

  5. The Smarter Water Manager
    6/14/2018

    Communities around the world are facing a growing storm. Complex challenges including water scarcity, changing demographics, extreme weather patterns, and aging or overly stressed infrastructure are colliding to threaten critical water, energy, transport, enterprise and health networks. The water industry is in the eye of the storm.

  6. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  7. Are You Experiencing Deviation Alarms In Your High Pressure Process Vessels?
    4/9/2018

    In this white paper, learn how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.

  8. How To Clean And Handle pH Sensors
    10/31/2017

    For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

  9. Bulk Emergency Chlorine Vapor Scrubber System Restored For Oklahoma City
    9/19/2017

    As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.

  10. U Of I Urbana-Champaign Implements Remote Monitoring System
    8/23/2017

    The Utility Distribution team at the University of Illinois at Urbana-Champaign manage the water system which serves the entire campus. The University purchases water from Illinois American Water which is distributed across the campus for uses as diverse as chemistry labs, agricultural research, and competitive swimming complexes.
