Drinking Water Treatment Application Notes

  1. 3M™ Liqui-Cel™ Membrane Contactors Can Help Meet Pure Steam Requirements In Pharmaceutical Industry
    8/10/2017

    Pure steam is used in sterilization chambers as a common method to sterilize pharmaceutical products, such as equipment parts, instruments, containers and materials for sterile environments.

  2. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution
    9/17/2014

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

  3. Water Distribution System Security Monitoring
    2/5/2013

    Ensuring safe drinking water doesn’t end when the water leaves the water treatment plant. Protecting the safety and security of drinking water from accidental or intentional contamination within the distribution system is becoming increasingly important.

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

    The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
  5. Non-Contact Radar Level Meter Improves Reactor Vessel Measurement
    7/4/2013

    A North Carolina-based specialty chemical manufacturer, a major producer of insect repellent, was looking for a better way to measure the liquid level in its glass-lined agitated reactor. The company uses a number of complex technologies to manufacture sebacates, adipates, isophthalates, catalysts, alkyds, and other natural and renewable chemistries based on castor and citrates.

  6. All WirelessHART Devices Are Not Created Equal
    12/4/2015

    Though they all must support routing functionality, some devices do it better than others.

    Routing consumes more energy, so the lifetime of the battery will be affected.  Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.

  7. Ultrasonic Level Measurement In Water And Wastewater Plants
    5/19/2016

    Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

  8. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications
    8/2/2015

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  9. Monitoring Nitrates In Drinking Water And Wastewater

    Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system.

  10. 3M™ Liqui-Cel™ Membrane Contactor Technology Being Evaluated For Dissolved Gas Removal From Water In Many Hydrocarbon Processes
    6/28/2017

    The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. In many hydrocarbon recovery and water processes, degassing is necessary in order to minimize environmental impact, improve operating efficiency, avoid process issues and help protect system components.
