Drinking Water Treatment Application Notes

  1. Application Note: Miami Conservancy District Uses Nitrate Screening As Conjunctive Management Tool
    1/20/2010
    Tasked with monitoring a watershed covering nearly 4,000 square miles, almost 2,300 miles of rivers and streams, and a huge aquifer that provides drinking water for more than 1.2 million people, water quality monitoring specialists at the Miami Conservancy District (MCD) in Dayton, Ohio, have their hands full.

  2. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility
    4/14/2016

    This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

  3. Dissolved Oxygen Measurement
    11/11/2013

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  4. Ultrasonic Level Measurement In Water And Wastewater Plants

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

  5. 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.

  6. Determination Of Pesticide Residues In Tea
    4/10/2015

    In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

  7. Protecting Pumps From Dead Head Conditions
    4/6/2017

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

  8. Precise Control Of Dissolved O2 And N2 In Semiconductor Applications Using 3M Liqui-Cel Membrane Contactors
    7/12/2017

    Semiconductor manufacturers increasingly want precise control of O2 and N2 concentrations in ultrapure water. Specifically, the polishing loop of a semiconductor plant needs to control dissolved O2 to low levels of 1 ppb or 5 ppb while simultaneously controlling the dissolved N2 between 8–12 ppm.

  9. Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application
    4/13/2017

    Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.

  10. Flow Meter Enhances Chlorination System Performance For Municipal Water Department
    12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.
