Wastewater Management White Papers and Case Studies

  1. Variable Speed Wastewater Pumping
    7/9/2015

    Wastewater pumps have traditionally been operated in an on-off mode for small as well as large wastewater pump stations. Because the inflow of wastewater is varying over time and is often only a fraction of a pump’s required capacity engineers have looked for ways to operate wastewater pumps at a reduced capacity in order to optimize performance while reducing operating costs.

  2. Pumps Reduce Costs, Improve Reliability, And Deliver Outstanding Energy Efficiency For Ohio WWTP
    7/8/2015

    An aging lift station in Marietta, OH, was the first of 12 stations to be upgraded as part of a capital improvement plan at the city’s wastewater treatment plant (WWTP).

  3. A Tale Of Two SCADA Conversions
    7/6/2015

    J.D. Irving, Limited Sawmill Division has invested $70 million in the latest operational equipment as part of their continuous investment in sustainable forest management strategies. In 2015, the company chose VTScada monitoring and control software to replace the aging SCADA systems used in their biomass boiler and trim line processes. Jody Gallant, an Electrical Engineering Technologist for JD Irving describes the some challenges and benefits of implementing a modern industrial SCADA system.

  4. Dripping Springs Water Supply Corp. Installs A VTScada System
    7/2/2015

    Serving a suburb of the Greater Austin Metropolitan Area, Dripping Springs Water Supply Corporation (DSWSC) recently decided to replace their Wonderware and WIN-911 system with VTScada, with the help of Austin area integrator, Central Texas Water Maintenance (CTWM).

  5. $9M Renovation Of Secondary Municipal Wastewater Treatment Facility
    7/1/2015

    Pangnirtung is an Inuit hamlet in the Canadian territory of Nunavut, located on Baffin Island. Fredericton based integrator, exp Services Inc., was selected for the nine million dollar renovation of Pangnirtung’s secondary municipal wastewater treatment facility. They chose VTScada for the brand new Supervisory Control and Data Acquisition (SCADA) system which gives the operators the ability to monitor and control the plant, receive alarms and notifications, view historical data trends and report.

  6. Sulzer Pumps Reduce Downtime At Water Utility
    6/26/2015

    Winslow Township — the largest town in Camden County, NJ — sought relief from its clog-prone, unreliable pumps.

  7. Cooling Process Control Panels Effectively
    6/25/2015

    Over the past few decades, the use of sophisticated high density electronics within automation and process control panels has become commonplace. Thermal management and its related costs for these electronic enclosures are very important considerations in managing these valuable assets. Choosing the appropriate and most cost and energy efficient cooling solution from the many types available requires knowledge of their individual strengths and weaknesses, and the ability to match that to the operational environment. By Doug Wilson, Noren Products Inc.

  8. Addressing Chronic Flooding In Texas
    6/18/2015

    The city of El Paso, TX, lies on the tip of the Chihuahuan desert, and it is not uncommon for a year’s worth of rain to occur in a matter of days during the summer.

  9. Continuous Analyzer Integrated Data Validation
    5/28/2015

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

  10. Five Years Of Post-Aeration At A Wastewater Treatment Plant
    5/28/2015

    To protect the environment, wastewater treatment facilities across the country are required to deliver dissolved oxygen (DO) into the treated effluent, with most DO permits ranging from 2 to 10 mg/L.
