Drinking Water Application Notes

  1. The Process Of Deionizing Water 10/29/2021

    Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

  2. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program 12/28/2005
    The Ipswich and Parker Rivers watersheds lie only a short distance north of Boston, MA. The first settlements in these watersheds began in the early 1600s. Since that time, residents have relied heavily on the natural resources of the Parker and Ipswich Rivers, their coastal estuaries and Plum Island Sound, which is known as the Great Marsh. This ecosystem has been designated and protected by the Commonwealth of Massachusetts as an Area of Critical Environmental Concern (ACEC).
  3. How Activated Carbon Works To Purify Air And Water 10/31/2019

    The first step is to define the performance limiting factors in the application. For this application, most of the adsorber is used for MTBE adsorption in the ppb concentration range. Adsorption of BTEX, TBA, or humic acids or other total organic carbon (TOC) components are removed by the front end of the column.

  4. Reduced Bore Electromagnetic Flowmeter 10/29/2021

    Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gain an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas. This includes supply planning, maintenance, resource deployment, leakage detection and the overall environment.

  5. 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.

  6. Determination Of Pesticide Residues In Tea 4/10/2015

    In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

  7. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS 6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

  8. 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.

  9. Application Note: Miami Conservancy District Uses Nitrate Screening As Conjunctive Management Tool 1/20/2010
    Tasked with monitoring a watershed covering nearly 4,000 square miles, almost 2,300 miles of rivers and streams, and a huge aquifer that provides drinking water for more than 1.2 million people, water quality monitoring specialists at the Miami Conservancy District (MCD) in Dayton, Ohio, have their hands full.
