  1. Free Chlorine Measurement In Drinking Water Treatment
    12/21/2005

    Before water can be used as a safe and reliable source for drinking water, it must be properly treated. Since water is a universal solvent, it comes in contact with several different pathogens, some of which are potentially lethal, and inactivation is accomplished through chemical disinfection and mechanical filtration treatment. This treatment consists of coarse filtration to remove large objects and pre-treatment which includes disinfection using chlorine or ozone

  2. Bottled Water Industry: Liquid Analytical Solutions
    11/11/2013

    Americans consume more than 9.1 billion gallons of bottled water annually - an average of twenty nine gallons per person every year.

    Doug Simmers, Product Manager, talks about the 6888 In-Situ Flue Gas Oxygen Analyzer and the Integral AutoCal feature.

  4. Application Datasheet: Desalination Of Sea Water
    10/16/2006
    Areas with large, growing populations and little fresh water resources are increasingly turning to desalination for their water needs. Many industrial plants and electrical utilities are located by the ocean so that they can be assured of a large, dependable, fixed-cost water supply. Seawater, however, is so corrosive that it is generally more cost effective to remove the salt than to replace piping or install pipe of more resistant materials.
  5. Improved Silo Contents Management Using 3D Solids Scanners
    5/7/2015

    Measurement of solids is a challenge for a number of reasons. The solids surface is uneven and shifts as the silo is filled or emptied.

  6. Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
    7/20/2015

    Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the vari­able frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sen­sors and analyzers from Emerson.

  7. Chlorine Measurement In Wastewater And Regulated Discharge Requirements
    8/8/2014

    Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

  8. Loop Calibration Made Easy
    1/29/2013

    The 56 advanced analyzer supports continuous measurement of analytical inputs from one or two sensors. The modular design allows signal input boards to be field replaced, making configuration changes easy. The high resolution full-color display gives unsurpassed visibility and functionality for analytical instrumentation.

  9. Application Note: pH Control Protects Membranes In Reverse Osmosis
    8/30/2005
    Reverse osmosis is a technique for removing dissolved solids from filtered raw water. It is used in a variety of industries to condition water for plant use, or as a first step in the demineralization process
  10. A Rosemount Chlorine Analyzer Proves Just The Job For Seawater Duty At Dow's Terneuzen Site
    4/20/2010

    The Dow Benelux site in Terneuzen, the Netherlands, uses seawater for process cooling. Environmental regulations require careful control of the concentration of chlorine added to control microbial fouling. The existing chlorine measurement system had become outdated, so after stringent tests Dow decided to replace it with a Rosemount Model TCL analyzer from Emerson Process Management.
