  1. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  2. Carbon Dioxide For pH Control Of Landfill Leachate
    6/16/2016

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  3. In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    6/16/2016

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.

  4. How Experts Justify The Cost Of Comprehensive SCADA In Drinking Water Plants
    5/31/2016

    Due to their critical role in protecting the health of customers, drinking water treatment systems require a high degree of care and oversight.

  5. Monitoring Lead In School Drinking Water
    5/23/2016

    The EPA’s guidance documentation “3T’s for Reducing Lead in Drinking Water in Schools and Child Care Facilities: Training, Testing, Telling” recommends for schools to routinely test their facility’s drinking water, with a focus on lead levels in drinking water fountains.

  6. Recognized Results Based On Quality Assurance And Quality Control

    Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.

  7. In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
    5/1/2016

    Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.

  8. From Zero To 2 Million
    4/29/2016

    Since 1977, Endress+Hauser has produced over two million electromagnetic flowmeters. That is more than any other manufacturer. “This magic number stands for high-quality measuring technology and, above all, satisfied customers in all kinds of industries,” says Bernd-Josef Schäfer, Managing Director of Endress+Hauser Flowtec AG, the center of competence for flow measuring technology.

  9. Precise Biogas Flow Measurement
    4/25/2016

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments

  10. Smart Antenna Technology Enhances AMI Network Reliability
    3/7/2016

    Advancements targeting the challenges related to a flooded meter pit environ­ment have occurred slowly over the years, with limited success.
