Drinking Water Application Notes

  1. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River 12/27/2005
    When replacement of the Sikorski Bridge spanning the Housatonic River was authorized, Paul Corrente and the Connecticut Department of Transportation (CT-DOT) set about the design and development of a water quality monitoring program to monitor the contractor’s in-water activities to insure full protection of the river from perturbation
  2. Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise 6/23/2021

    Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

  3. LC-MS/MS Analysis Of PFAS Extractables In Polyethersulfone Syringe Filters Using EPA 537.1 5/18/2022

    A key consideration for any PFAS method is to avoid contamination that can impact the accuracy of data, including those coming from sample preparation techniques such as filtration.

  4. Bridge Crossings And The Proper Use Of EX-TEND®, FLEX-TEND®, And Force Balanced FLEX-TEND Products 11/1/2020

    Of particular interest when it comes to bridges is the locating of pressurized water lines on and under bridge structures. Pressurized pipelines can present a number of unique challenges to the design engineer and utility owner.

  5. LC-MS Analysis Of 33 PFAS Compounds In 5 Minutes 11/4/2021

    In response to environmental testing demands for faster LC-MS analyses, the new Ascentis® Express PFAS HPLC and delay columns allow the highly efficient separation of 33 PFAS compounds in 5 minutes with reduced background contamination.

  6. Reduce Or Eliminate Water Hammer With Valve Positioners 5/19/2022

    Water hammer, which can occur in just about any pumping system and even steam systems, can lead to pipe breakage, equipment damage or even total system failure. Addressing water hammer at the source is the savviest and most cost-effective way to handle the issue.

  7. Aquafine Ultraviolet Treatment Systems For TOC Reduction 1/29/2025

    Aquafine TOC reduction units coupled with ion exchange systems or EDI will oxidize trace organics into smaller ionic species, carbon dioxide and water, which are more readily removed by ion exchange resins, EDI, and/or degasifiers.

  8. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants 8/30/2005

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter

  9. Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants 1/15/2019

    Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

  10. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water 4/5/2013

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).
