Drinking Water Treatment Application Notes

  1. Hot CIP Sanitization Procedure For 3M™ Liqui-Cel™ Membrane Contactors In Stainless Steel Housings
    6/7/2017

    Hot Clean-In-Place (CIP) sanitization is commonly used to combat microbial growth in the pharmaceutical and food and beverage industries. Performed frequently as a prevention strategy, hot water sanitization is a requirement for high purity water (HPW) for United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.).

  2. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)
    12/30/2013

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

  3. 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.

  4. 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.

  5. 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
  6. Phosphate Corrosion Control In Drinking Water
    11/21/2012

    Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides.

  7. (E)-2-Nonenal In Beer
    4/5/2015

    Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.

  8. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
    12/28/2005
    The Ipswich and Parker Rivers watersheds lie only a short distance north of Boston, MA. The first settlements in these watersheds began in the early 1600s. Since that time, residents have relied heavily on the natural resources of the Parker and Ipswich Rivers, their coastal estuaries and Plum Island Sound, which is known as the Great Marsh. This ecosystem has been designated and protected by the Commonwealth of Massachusetts as an Area of Critical Environmental Concern (ACEC).
  9. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands
    2/3/2011
    The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
  10. Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety
    9/28/2005
    A water utility in Ohio wanted to learn more about the variability of water quality parameters such as pH, ORP, turbidity, and chlorine. Previously, most of these parameters had been measured by spot sampling protocols with only a few measurements during a daily period. In order to more accurately assess the water variability, the utility used a YSI 6920DW Drinking Water Multiprobe
