Wastewater Treatment Application Notes

  1. Reducing Total Phosphorus In Water Resource Recovery Facilities
    9/10/2014

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

  2. 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.

  3. Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution
    10/16/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

  4. Reduce SBR Maintenance Costs With Jet Aeration
    6/16/2017

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

  5. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood
    4/20/2015

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

  6. Validation Of Environmental Water Methods On One System
    4/6/2015

    Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.

  7. 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.

  8. Application Note: Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography

  9. 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.

  10. Increase Ink Jet Print Speeds By 15% With 3M™ Liqui-Cel™ SP Series Membrane Contactors
    6/30/2017

    Many high-speed, wide-format ink jet printer manufacturers are now using 3M™ Liqui-Cel™ SP Series Membrane Contactors to remove air bubbles and excess gases from ink to reduce downtime and improve yields. Entrained bubbles and excess gases are often the cause of printing surface defects and ink flow interruptions that can cause printer shut-downs.
