Drinking Water Treatment Application Notes

  1. The Basics: Keeping Our Water Clean Requires Monitoring
    4/30/2014

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  2. Determination Of Pesticide Residue In Vegetables

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

  3. Application Note: YSI 600 Optical Monitoring System Used To Protect Lake Oconee, Georgia Water Quality
    12/27/2005
    Northern Georgia is experiencing unprecedented development; consequently, water quality in many of its watersheds is in jeopardy of severe degradation. The State of Georgia, Environmental Protection Division (EPD) has implemented an NPDES monitoring and enforcement program designed to prevent construction activities from impacting water quality
  4. Benefits Of UV Transmittance (UVT) Field Testing For Selling & Servicing UV Disinfection Systems
    2/1/2013

    The Real UV254 'P' series portable meters can be used to measure UV transmittance (UVT) in a number of situations, and are especially beneficially when working with small UV disinfection systems. The following cases outline two situations in which Real Tech's portable meters are invaluable.

  5. Application Note: Water Flows From The Golden Hills Of California

    Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI
  6. 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.

  7. 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.

  8. Wireless PRV Monitoring Application Note
    11/21/2013

    Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.

  9. 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.

  10. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands
