    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  2. 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.

  3. The Basics: Monitoring Deionized Water
    5/1/2014

    Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

  4. Monitoring Aromatic Organics For Optimizing Coagulation
    2/1/2013

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

  5. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants
    8/30/2005

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter

  6. Harmonics Reduction Methods
    4/17/2017

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

  7. The Basics: ORP and Free Chlorine Monitoring
    5/13/2014

    Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.

  8. Technical Note: Using 3M Liqui-Cel Membrane Contactors To Solve Resistivity Problems In A High Purity Water Loop

  9. Removal Of Chloramines With Activated Carbon
    12/30/2013

    In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

  10. Dissolved Oxygen Measurement
    11/11/2013

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.
