  1. 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.

  2. 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.

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 The existing chlorine measurement system had become outdated, so after stringent tests Dow decided to replace it with a Rosemount Model TCL analyzer from Emerson Process Management.

  8. Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
    5/22/2006

    Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks.
