  • Carbon Dioxide For pH Control Of Landfill Leachate
    Carbon Dioxide For pH Control Of Landfill Leachate

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

    Starting in 2010, the drinking water plant in Wellsboro, PA, began experiencing high turbidity and algae in the water which caused emergency notices for citizens to boil their water before use.

  • The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)
    The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)

    A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

  • Lightning Fast Response Prevents Extended Down Time
    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.

  • Turbiwell Comparision Report Before And After Upgrade
    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. 

  • Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
    Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers

    Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the vari­able frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sen­sors and analyzers from Emerson.

  • Chloramination Monitoring And Control
    Chloramination Monitoring And Control

    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.

Continuous Analyzer Integrated Data Validation
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.

Real-Time Monitoring Aids Adoption Of New Water Treatment Technologies Real-Time Monitoring Aids Adoption Of New Water Treatment Technologies

With the ability to store mass amounts of data, real-time monitoring and the timely analysis of that data is spurring significant change in the water industry. As Rick Bacon, CEO of Aqua Metrology Systems, explains in this Water Talk interview, high frequency data is not only aiding in the battle to identify contamination but also in summarizing performance once a solution has been installed to fix it.

Microbial Contamination Monitoring For Water Distribution Systems Microbial Contamination Monitoring For Water Distribution Systems

Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.

Water Regulations Change As Data Accuracy Intensifies Water Regulations Change As Data Accuracy Intensifies

It makes sense that water regulations are written in line with the available means to detect contaminants. The same logic would suggest that as newer, more accurate diagnostic technologies become available, the list of MCLs and the depth of water regulations will continue to evolve.

Understanding Big Data In The Water Industry Understanding Big Data In The Water Industry

There’s a lot of data floating around the water industry these days. SCADA, flow statistics, online monitoring, DO measurements, air flows, LIMS system data in the Lab, and CMMS data from maintenance software to name but a few.

Mazzei Degas Separators Selected For Wichita Aquifer Project Mazzei Degas Separators Selected For Wichita Aquifer Project

A key component of the water supply plan for the City of Wichita, Kansas, was recharging the large aquifer that lies under the region with water from the Little Arkansas River. The river basin contains substantial farming operations which, during rain events, spike the river water with the commonly used herbicide Atrazine. Atrazine concentrations in the river frequently rose forcing the city to shutdown the bank filtration system. Advanced oxidation process (AOP) was selected to remove the herbicide. The AOP reactor’s design limited the amount of hydraulic backpressure it could tolerate. Consequently, Mazzei was challenged by the project’s design team to remove the entrained gas bubbles that remained from the prior oxidation treatment at a “not to exceed” hydrostatic backpressure of 19 feet.
