Wastewater Application Notes

  1. 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.

  2. 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.

  3. 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.

  4. Harmonics Reduction Methods
    4/17/2017

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

  5. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    10/16/2014
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  6. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution
    9/17/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  7. Protecting Pumps From Dead Head Conditions
    4/6/2017

    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.

  8. Chemical Cost Comparison Of A Conventional Deaerator vs. A 3M™ Liqui-Cel™ Membrane Contactor System
    6/27/2017

    Mixed bed ion exchange is often used to polish reverse osmosis (RO) permeate in many industrial water systems. This process has been utilized for several years and it is well known that the management of the dissolved carbon dioxide (CO2) in the water is critical for an efficient operation. By Membrana
