  1. Think You Know ORP? Get 5 pH/ORP Measurement Tips
    6/29/2017

    Water and wastewater treatment professionals are constantly looking for as much information as possible about the quality of their water. If knowledge is power, then understanding the properties of their water is key to running an effective and efficient facility.

  2. Wireless pH Monitoring Of Storm Water Runoff And Final Effluent
    3/1/2010

    Wireless pH instrumentation is appropriate in several applications in the power industry. The principal benefit of a migration to wireless technology from more traditional copper cable is cost reduction. A wireless network requires none of the cable, conduit, or switching hardware which represent the largest expense in most plant networks. By Emerson

  3. 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

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

  5. New Emerson Combustion Control Analyzer For Small And Midsize Boiler Users Helps Meet Energy And Environmental Requirements
    4/4/2018

    To improve energy efficiency and meet environmental regulatory requirements for small and midsize boiler markets, Emerson introduces the Rosemount CX1100 in situ oxygen analyzer, the first high-performance, zirconia cell-based combustion control system designed for these users.

  6. 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.

  7. Smart Wireless Technology Solves Environmental Monitoring Challenge
    10/31/2013

    Faced with the challenge of meeting environmental monitoring legislation, Korsnäs Gävle needed a way to monitor water from their heat exchangers for contamination before discharging it to the sea. Additionally, the board and paper manufacturer required new sensors for continuous monitoring of pH, dissolved oxygen, and water temperatures from effluent emissions in their basins and ponds. In this case study, learn how Korsnäs Gävle implemented a wireless sensor network to quickly  achieve compliance and meet its monitoring needs.

    Averting regulatory violations and fines. Avoiding system disruptions. Maintaining effective monitoring in complex applications. How do you tackle these kinds of age-old plant monitoring problems? 

  9. 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.

  10. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants
    8/30/2005

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter
