Wastewater Instrumentation Application Notes

  1. 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.

  2. VFD Energy Savings For Pumping Applications

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

  3. Protecting Pumps From Dead Head Conditions

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

  4. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

  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. New Ultrasonic Flow Meters Improve Biogas Measurements
    9/20/2016

    As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

  7. Optimize Your Water Discharge Quality Through Accurate Turbidity And Suspended Solids Measurement
    6/23/2016

    The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.

  8. Ultrasonic Level Measurement In Water And Wastewater Plants
    5/19/2016

    Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

  9. All WirelessHART Devices Are Not Created Equal
    12/4/2015

    Though they all must support routing functionality, some devices do it better than others.

    Routing consumes more energy, so the lifetime of the battery will be affected.  Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.

  10. 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.
