  1. SWAN Distribution Quality Monitors – Multiple Parameters; One Simple Panel 9/15/2017

    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 7/15/2016

    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 5/18/2015

    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 8/2/2015

    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 7/29/2015

    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. Turbiwell Comparision Report Before And After Upgrade 7/29/2015

    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.

  7. Chloramination Monitoring And Control 7/15/2015

    Since the EPA has established that, together with free chlorine, monochloramine is a primary disinfectant, it has been possible to implement the process more intensively. Water that is treated with monochloramine has, depending on the source of the water, fewer problems concerning taste and odor than water treated with free chlorine. In addition, the chemically more stable monochloramine remains longer in the water, thus allowing a long-term disinfecting effect.

  8. Drinking Water Disinfection – A History And Improved Monitoring Techniques 7/3/2015

    In many countries we take for granted the availability and reliability of safe drinking water.  A recent trip outside of the US reminded me of this fact when I saw notices in the hotel rooms stating the drinking water met specific standards and was safe to drink however, my friends from the country emphatically warned me to not drink the water.

  9. Monitoring Chlorine Residuals For RO Membranes - ORP Versus Chlorine Analyzers 7/14/2015

    In processes where disinfection is required chlorine is the most common and economic disinfectant followed by sodium hypochlorite (liquid bleach). It is important to disinfect the RO feedwater to avoid fouling of the membranes which results in poor performance and frequent cleaning.

  10. Monochloramine Monitoring – Reliable Analysis, Safer Drinking Water 6/30/2015

    The Safe Drinking Water Act (SDWA), enacted in 1974, is the main federal law that ensures the quality of Americans' drinking water. Under SDWA, EPA sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards. The law was amended in 1986 & 1996 requiring many actions to protect drinking water and its sources.
