Wastewater Treatment Application Notes

  1. Determination Of Hexanal In Foods Utilizing Dynamic Headspace
    4/9/2015

    Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

  2. 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.

  4. 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.

  5. Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography
    2/6/2011
    This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA
  6. Aerated Biological Nitrogen Removal
    7/16/2013

    Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

  8. Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
    9/18/2017

    With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

  9. Microbial Control In Cheese Making
    12/5/2014

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
