  1. SWAN Distribution Quality Monitors – Multiple Parameters; One Simple Panel

    The SWAN DIST series Distribution Quality Monitor line offers three options for measuring chlorine, pH, conductivity and turbidity on one easy to install, easy to maintain panel. Versatile output options ensure water quality throughout your distribution system, proving piece of mind and customer satisfaction.

  2. The Benefits Of Continuous Monitoring Of Phosphate In Corrosion Control

    When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.

  3. Chicago Suburb Ensures Highest Water Quality Year-Round, Saves On Labor And Reagents With New Chlorine Analyzers

    For the Village of Lombard’s Water Division, consistently delivering high-quality tap water to the community’s nearly 44,000 residents and the businesses serving them was once quite a juggling act: constantly fixing old, temperamental analyzers; feeding reagents into the old analyzers; and staying ahead of callers complaining about “musty” water tastes and odors. Not today.

  4. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  5. Lightning Fast Response Prevents Extended Down Time

    The City of Gordon Texas’s drinking water facility was struck by lightning. Thinking long term, and desiring the latest technology available, the City took this opportunity to upgrade their on-line instrumentation with a range of new continuous monitoring on-line instruments including chlorine analyzers, pH monitoring, temperature monitoring, and turbidity monitoring.

  6. Continuous Analyzer Integrated Data Validation

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

  7. Turbiwell Comparision Report Before And After Upgrade

    Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters. 

  8. Internet-Enabled Water Quality Analysis

    The Internet of Things (IoT) has arrived at the water authority. Online analyzers sampling water quality 24/7 are being coupled with software running on mobile computing devices such as cellphones and tablets to provide the modern utility worker with up-to-the-minute results.

  9. Innovations In UV Oxidation Direct Conductivity TOC Measurement To Improve Accuracy And Precision

    This report gives a brief outline of the general measuring methods. Further, it illustrates the possibilities and limitations of the direct UV oxidation, as well as which technical modifications were made to the monitoring instrument, AMI Line TOC, to improve the performance of the UV reactor and, therefore, the precision of the instrument.

  10. Water Plant Applies Colorimetric Chlorine Analyzer To Accurately Measure Proper Chloramination

    The North Shore Water Commission located in Glendale Wisconsin is a conventional water treatment facility that receives its influent from Lake Michigan. At the intake, chemical treatment is applied for mussel control and the water is pumped to the treatment plant 1 mile away. By Kevin Forsman
