Drinking Water Application Notes

1. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
   7/6/2017

   ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

2. Ultrapure Water For Determination of Toxic Elements In Environmental Analyses
   4/10/2018

   In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

3. Defining Drinking Water Plant Backwash Profile Using The SOLITAX™ Sc Suspended Solids And Turbidity Sensor
   6/7/2013

   Today’s drinking water plants have many challenges to meet as they produce water for a fast-growing and increasingly demanding population.

4. 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.

5. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
   10/16/2014
   Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
6. How To Read An Encoder
   9/13/2013

   The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.

7. Real-Time Conductivity Monitoring Estimates Chloride Levels In Minnesota Watershed By Using The Aqua TROLL 200
   11/18/2011
   Monitoring deicing chemical levels can help researchers, city governments, and regulatory agencies understand runoff impacts on surface water, groundwater, and surrounding environments.
8. Technical Note: Using 3M Liqui-Cel Membrane Contactors To Solve Resistivity Problems In A High Purity Water Loop
   1/30/2009

   Pureflow, Inc. is a Southeastern-based expert in designing complete water treatment systems as well as providing value-added solutions for fixing operational issues in existing systems. Pureflow teamed up with Membrana to help solve an operational issue at one of their customer’s facilities. By Membrana

9. The Basics: Testing RO Quality
   4/28/2014

   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.

10. Network Monitors Water Quality In Shale Gas Drilling Region
    9/2/2011
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars.
