Drinking Water Application Notes

  1. Free Chlorine Measurement In Drinking Water Treatment 12/21/2005

    Before water can be used as a safe and reliable source for drinking water, it must be properly treated. Since water is a universal solvent, it comes in contact with several different pathogens, some of which are potentially lethal, and inactivation is accomplished through chemical disinfection and mechanical filtration treatment. This treatment consists of coarse filtration to remove large objects and pre-treatment which includes disinfection using chlorine or ozone

  2. Why Should We Care About NSF/ANSI 61 Certification? 3/17/2021

    According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.

  3. Pipe Repair On A Budget 3/7/2014

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  4. Advances In Paper-Based Devices For Water Quality Analysis 2/22/2017

    Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

  5. Removal Of PFCs With Activated Carbon 12/30/2013

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

  6. Alcoholic Beverage Fusel Alcohol Testing With Static Headspace 9/2/2014

    A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

  7. Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution 10/16/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

  8. Real-Time Conductivity Monitoring Estimates Chloride Levels In Minnesota Watershed By Using The Aqua TROLL 200 11/18/2011
    Monitoring deicing chemical levels can help researchers, city governments, and regulatory agencies understand runoff impacts on surface water, groundwater, and surrounding environments.
  9. The 'First Line Of Defense' In Protecting Membrane Filters 8/9/2019

    Multi-element, self-cleaning pretreatment filters optimize membrane filter life and production while minimizing maintenance and downtime.

  10. Leak Detection On Water Distribution Network Using Clamp-On Flowmeters 5/22/2023

    A global engineering company realized that their leak identification methods were time consuming and expensive, and so began to explore alternative solutions, such as ultrasonic flow meters.
