Wastewater Measurement White Papers and Case Studies

  1. City Saves Money And Energy With Real-Time Control System
    12/12/2013

    Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.

  2. City of Troy Improves Customer Relationships And Billing Accuracy With AMI Solution
    3/28/2018

    Located just south of Montgomery, Alabama, the City of Troy is a unique mix of southern small-town charm and big-city amenities. Read the full case study to learn how the City leveraged Sensus’ Advanced Metering Infrastructure (AMI) solution to gather more data and monitor for issues likes leaks or pipe breaks

  3. How Can Seasonal Establishments Treat Their Wastewater Economically?
    2/20/2014

    Opened a few months per year, seasonal establishments typically experience important fluctuations in the number of visitors. Energy consumption and operating expenses must continually be analysed and optimized. The implementation of efficient energy management practices and the integration of innovative wastewater treatment solutions that can improve their cost-efficiency ratio have become major sources of savings for this whole industry.

  4. Leveraging IIoT Technologies To Reduce Unplanned Downtime
    1/1/2019

    At ARC Advisory Group’s 20th Annual Industry Forum in Orlando, Florida, Shawn Anderson, Senior Research Specialist for Fisher Valves, a division of Emerson Process Management, gave a presentation on how the company is leveraging the Industrial Internet of Things (IIoT) to help end users reduce valve-related unplanned downtime.

  5. Building An Invisible And Soundless Power Plant
    6/23/2017

    The Villoresi Channel, located north of Milan, was designed with the main purpose of agricultural irrigation while providing water to the city of Milan. The paths running along the canal were also used for recreational purposes and cross through some of the most beautiful natural parks in Lombardy.

  6. Two Processes, One Flow Metering Technology: The Benefits Of Standardization
    3/21/2018

    Wastewater treatment facilities use multiple processes and a variety of equipment to produce water clean enough for reuse. Each process within the treatment train may serve a different function yet use the same or similar equipment. In such cases, standardizing equipment may be beneficial.

  7. White House Utility District Reduces Costs By Over $1 Million
    12/3/2018

    In 2007, White House Utility District (WHUD), a water utility serving approximately 90,000 consumers and businesses in Tennessee, faced a dilemma: how to meet a projected growing demand for water within the budget and capital constraints faced by municipal and mid-sized utilities everywhere.

  8. Aeration Basin Air Flow Monitoring At A Stockholm Wastewater Plant
    12/20/2013

    At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

  9. Case Study: Continuous Online Monitoring Of Nitrate And Sludge Using UV/VIS Spectroscopic Sensor
    8/18/2009

    Monitoring nitrates, total suspended solids and sludge volume concentrations ensures effluent quality, which is critical for meeting water quality standards for various regulatory agencies. By Endress+Hauser, Inc.

  10. ORP Sensors – Are They Really The Best Thing “Since Sliced Bread”?
    12/12/2016

    There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
