Nutrient Removal Application Notes

  1. AquaSBR Sequencing Batch Reactor: Food And Beverage Industry 12/6/2023

    This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

  2. 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.

  3. Improving Compliance Through Real-Time Phosphorus Control 4/18/2017

    Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

  4. Total Kjeldahl Nitrogen: Simplified With s-TKN™ 7/15/2013

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.

  5. 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
  6. 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.

  7. Application Note: Testing Nitrite In Surface Water And Wastewater 4/25/2011
    The Thermo Scientific Orion AQUAfast® AQ3700 Colorimeter comes programmed with methods for testing nutrients. By Thermo Fisher Scientific
  8. Orion DUAL STAR™ Quick Start Note - Nitrate In Water & Wastewater 7/31/2009
    The Thermo Scientific Orion DUAL STAR meter shows the results of both input channels simultaneously.
  9. Application Note: Building A Baseline In Florida 5/25/2006
    The Florida Department of Environmental Protection (DEP) knows that establishing dissolved oxygen (DO) and nutrient criteria for the state’s water bodies is a challenge – both scientifically and politically
