Drinking Water Treatment Application Notes

  1. 3M™ Liqui-Cel™ Membrane Contactors Are Widely Used In The Soft Drink And Brewing Industries To Control Dissolved Gasses
    7/10/2017

    Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product.

  2. Application Note: Real-Time Monitoring-Through Swell And High Water

  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. 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.

  5. Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
    1/20/2010
    As with other watershed organizations, the Busseron Creek Watershed Partnership (BCWP) exists because of surface water quality degradation. In this case, those waters drain 163,231 acres of a watershed that crosses the boundaries of Vigo, Clay, Green, and Sullivan counties in West- Central Indiana. By YSI
  6. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
    12/27/2005
    When replacement of the Sikorski Bridge spanning the Housatonic River was authorized, Paul Corrente and the Connecticut Department of Transportation (CT-DOT) set about the design and development of a water quality monitoring program to monitor the contractor’s in-water activities to insure full protection of the river from perturbation
  7. Chinese Chemical Plant Optimizes Water Treatment By Replacing Double Pass RO With A Single Pass RO And 3M Liqui-Cel Contactor System
    6/1/2016

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment.

  8. The Importance Of Measuring Total Organic Carbon
    4/13/2017

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

  9. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
    12/1/2017

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

  10. Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability
    1/20/2010
    In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
