Wastewater Application Notes

  1. Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography
    2/7/2011
    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
  2. Primary Wastewater Treatment: Influent Monitoring
    11/11/2013

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  3. Application Bulletin: Reverse Osmosis
    3/19/2008
    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
  4. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
    7/6/2017

    ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

  5. Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
    8/4/2011
    Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day. By YSI
  6. Analyzing Total Organic Carbon In Sea Water
    4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  7. Optimize Your Water Discharge Quality Through Accurate Turbidity And Suspended Solids Measurement
    6/23/2016

    The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.

  8. 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.

  9. 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.

  10. Degassing Sea Water Has Never Been This Compact, Efficient, And Adaptable
    6/27/2017

    3M™ Liqui-Cel™ Membrane Contactors offer a modular skid option for off-shore oil platforms that is significantly smaller and lighter than traditional vacuum towers.
