Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies
Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies

For decades, a Winnipeg utility used a multiple point-chlorination process to treat raw water drawn from remote Shoal Lake. Concerns eventually arose about the potential presence of chlorine-resistant pathogens–Crytosporidium and Giardia–and residual disinfection byproducts, which coincided with encroaching development near the lake. The Clari-DAF system was selected and now removes 70 percent of the organics at the Winnipeg plant, which also improves filtration and extends the intervals between filter backwashes.

    The City of Wilmington, Delaware is situated where the Christina River and the Brandywine Creek flow into the Delaware River.

  • High Turbidity Water Treatment Reached With Mobile Water System
    High Turbidity Water Treatment Reached With Mobile Water System

    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.

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.

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.

DRINKING WATER ANALYSIS NEWS AND HEADLINES

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

The Mazzei GDT™ Degas Separator is a patented unit that utilizes centrifugal force to create a vortex enabling entrained gases to be extracted from water. The water-entrained gas mixture enters the top of the separator tangentially and flows through an accelerator plate, which increases velocity. The water spins down through the separator and exits the bottom. The entrained gas travels through the vortex where it passes into a collector and flows out the top of the separator. The separated gasses exit the separator through a degas relief valve.
