  1. How Do I Calibrate My pH Sensor?
    11/7/2013

    In this video, learn how to properly perform a two-point calibration on a pH Sensor.

  2. 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.

  3. Coagulation and Flocculation
    9/18/2013

    Water is clarified using the processes of coagulation and flocculation, which remove suspended solids (turbidity) from water by causing the suspended particles to aggregate into a slime, that settles out of the water.

    Introducing the easy-to-use Model 56 Analyzer. The high resolution full-color screen provides easily viewed process measurements, on-screen data trend graphs, and details user help screens. This advanced analyzer has data logger, event logger, and a USB 2.0 data port.

  5. 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.

  6. 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

  7. 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.

  8. Continuous Total Chlorine Measurement And Recording To Meet EPA Discharge Requirements
    11/21/2011

    Total chlorine can be determined using the Rosemount Model TCL. This system is a sample conditioning and measuring system for the continuous determination of total chlorine in water.

  9. 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.

  10. Application Note: Ozone Measurement In Potable Water
    3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.
