Drinking Water Application Notes

  1. Circuit Board Cleanliness Testing 10/29/2021

    Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.

  2. The Active Control Program For Advanced UV Oxidation 12/1/2025

    This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

  3. Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCA 2/19/2014

    The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.

  4. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands 2/3/2011

  5. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS 10/1/2014

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

  6. Aries Arsenic Reduction 1/7/2026

    Arsenic has no smell, taste, or color when dissolved in water even in high concentrations. It is a potential concern to those who live in areas with high natural deposits of arsenic, receive runoff from orchards, or from glass and electronic production waste.

  7. Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise 6/23/2021

    Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

  8. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution 9/29/2014

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

  9. 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.

  10. Immediate pH Correction For Fluctuating Flow 2/19/2014

    In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements.  Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.
