Wastewater Application Notes

  1. How One Wastewater Treatment Plant Saved Time And Money Measuring Turbidity And TSS
    1/31/2012
    The wastewater treatment plant of a major corporation is designed for a population capacity of 6 million people and is considered a very large wastewater treatment plant.
  2. 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
  3. Repair Or Rethink
    8/7/2015

    The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

  4. Comparison Of Alkagen® Solution To Other Alkaline Technologies For Odor And Corrosion Control
    2/1/2016

    Evoqua’s team of engineers and scientists is widely recognized as the most experienced and authoritative body of odor and corrosion control specialists assembled within any vendor organization worldwide.

  5. Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    12/15/2017

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

  6. Hot CIP Sanitization Procedure For 3M™ Liqui-Cel™ Membrane Contactors In Stainless Steel Housings
    6/7/2017

    Hot Clean-In-Place (CIP) sanitization is commonly used to combat microbial growth in the pharmaceutical and food and beverage industries. Performed frequently as a prevention strategy, hot water sanitization is a requirement for high purity water (HPW) for United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.).

  7. Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution
    9/24/2014

    Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

  8. Control Of THMs With Chlorine Dioxide
    2/16/2016

    Chlorine dioxide (ClO2) is effective as both a disinfectant and an oxidant in water and wastewater treatment.

  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. 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.
