Drinking Water Application Notes

81. 3M™ Liqui-Cel™ Membrane Contactors Improve Water Quality and EDI Performance
    6/27/2017

    Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.

82. Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
    5/31/2011
    Total bound nitrogen (TN_b) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TN_b measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

83. 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

84. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
    12/1/2017

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

85. 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.

86. Bringing Efficiency And New Confidence To BOD₅ Analysis
    2/4/2013

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

87. How To Install A Submersible Pump In Discharge Tubes
    11/28/2012

    In the fields of water and waste water technology, submersible pumps represent a viable economic and technical alternative to conventional, dry-installed pumps. In particular, they offer a number of handling advantages during maintenance and installation work, a factor of increasing importance in times of general staff cutbacks by operating companies.

88. Application Note: Real-Time Monitoring-Through Swell And High Water

89. The Importance Of Measuring Total Organic Carbon
    4/13/2017

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

90. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood
    4/20/2015

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.
