  1. Dissolved Oxygen Measurement In Wastewater Treatment
    11/11/2013

    A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

  2. SMART pH Sensors And Instruments For Plug And Play Use
    2/27/2013

    Linda Meyers explains how SMART pH sensors and instruments help customers solve challenges like calibrating sensors in remote locations where buffer solutions, beakers, and a rinse bottle must all be carried on site, making it cumbersome and time consuming.

  3. A Rosemount Chlorine Analyzer Proves Just The Job For Seawater Duty At Dow's Terneuzen Site
    4/19/2010

    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 The existing chlorine measurement system had become outdated, so after stringent tests Dow decided to replace it with a Rosemount Model TCL analyzer from Emerson Process Management.

  4. Application Note: Chlorine Measurement By Amperometric Sensor
    6/2/2009
    Chlorine in aqueous solutions is used for a number of purposes such as disinfection, taste and odor control, bleaching, and as a powerful oxidizing agent in various manufacturing processes. Chlorine is a costly chemical and requires large amounts of energy to produce. About 3000 KWH are required to produce a ton of chlorine from brine, and the delivered cost ranges from $160 to $300 per ton. As energy becomes more expensive, so inevitably will chlorine.

    Almost every industrial setting poses some potential safety risk to personnel working in such environments whether it is something that can be seen such as rotating machinery or unseen, such as possible lethal concentrations of flammable/combustible gas.

  6. 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
  7. Bottled Water Industry: Liquid Analytical Solutions
    11/10/2013

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

  8. How One Plant Found Great Service Through Turbidity Analyzers
    10/3/2016

    The nearly 16,000 people in Calhoun, GA, rely on two drinking water treatment facilities — one that pulls its water from a river and another that pulls from groundwater — that process about 9 MGD. The turbidity of the river’s water can fluctuate dramatically, so the operators rely on the surface water treatment plant’s turbidity analyzers to ensure that they are serving the population as they should.

  9. Improved Process Control: Putting ‘Knowledge Is Power’ To Work
    10/20/2017

    You can’t control what you don’t know and when it comes to gas mixtures, control is of vital importance. But how can you get a handle on all of the elements you’re processing at a given time?

  10. Leak Detection Using Conductivity
    11/11/2013

    Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
