Water Instrumentation Application Notes

  1. VOC Headspace 10/29/2014

    Static headspace is one of the most popular techniques due to its versatility for analyzing volatile organic compounds (VOCs) in a complex variety of matrices. This is due to the elimination of tedious sample preparation steps and prevents contamination problems that are common to other sample introduction techniques. Teledyne Tekmar draws on our experience as a leader in low-level VOC analysis with the introduction of this companion autosampler to the Headspace product line.

  2. MD3 CHEM-FEED® Multi-Diaphragm Metering Pump 9/18/2024

    The MD3 Multi-Diaphragm Metering Pump delivers smooth, continuous chemical feed even when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite.  The cutting-edge Hyperdrive Technology allows for alternating pumping action between two diaphragms: when one diaphragm is in the suction phase, the other is in the discharge, resulting in a smooth chemical feed profile and eliminating the chance of vapor lock and loss of prime.

  3. Myers 3" Vortex Pumps 12/18/2012

    Myers 3R and 3RX (hazardous location) submersible wastewater pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected.

  4. Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability 1/20/2010
    In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
  5. Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection 9/22/2022

    A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

  6. 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.

  7. Sound Attenuated Prime Assisted Solids Handling Pump 4/17/2023

    This sound attenuated pump eliminates the need for a waste hose and prevents discharge of pumping effluent onto the ground. 

  8. Add-On Type Turbidity Meter: PipeTalk™(WM-2000) 9/12/2024

    World's first real-time drinking water quality monitoring sensor for smart water meter. Online membrane integrity monitoring sensor for every vessel.

  9. Smith & Loveless Flooded Suction Non-Clog Pump 4/8/2011

    Tens of thousands of proven Smith & Loveless Non-Clog Pumps convey wastewater around the world, providing reliable service day-in and day-out.

  10. LST200 Ultrasonic Level Transmitter: The Easy Choice For Intelligent Level Measurement 9/28/2020

    In water and wastewater treatment applications, a product that offers simple commissioning, reliable operation, fast delivery, and easy maintenance offers tremendous customer value.
