Wastewater Treatment Application Notes

  1. 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.

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

  3. Mapping And Identifying The Source Of Water Quality Issues
    6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  4. Applying Oxidation Reduction Potential Sensors In Biological Nutrient Removal Systems
    2/3/2012
    Oxidation Reduction Potential (ORP) is commonly a misunderstood science. Applying ORP to wastewater treatment is often a considered a mystery and sometimes called “black magic”. By Bob Dabkowski Hach Wastewater Specialist
  5. Primary Wastewater Treatment: Influent Monitoring
    11/11/2013

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  6. Analyzing Total Organic Carbon In Sea Water
    4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  7. Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    3/3/2015

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.

  8. Ion Exchange Resins Reduce Pollution From Refineries
    12/23/2013

    A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

  9. Membrane Degassing and Debubbling of High Viscous Fluids with 3M™ Liqui-Cel™ Membrane Contactors
    6/28/2017

    Increased gas content often leads to problems with bubble formation in highly viscous fluids. 3M™ Liqui-Cel™ Membrane Contactors can provide a simple, compact, and efficient in-line solution for removing bubbles from viscous liquids before they create problems in a process operation.

  10. 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.
