Wastewater Treatment Case Studies and White Papers

  1. VTScada And OpWorks Provide Advanced Wastewater Reporting And Analysis
    11/17/2015

    Rapid City is the second-largest city in South Dakota, serving over 72,000 residents. Their Water Reclamation Department treats nearly 3.5 billion gallons of wastewater annually.

  2. Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker
    12/6/2016

    The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.

    In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.

  3. Recognized Results Based On Quality Assurance And Quality Control
    5/11/2016

    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.

  4. Case Study: Dr. Roddy Tempest And The Ultrameter II In Disaster Response
    3/19/2008

    Find out how the Ultrameter II gave Dr. Tempest fast accurate results that let him act quickly and help save the lives of thousands of people.

  5. Maximum Water Reuse, Zero Liquid Discharge — A Power Plant Case Study
    3/1/2015

    ELCOGAS, established in 1992 with the aim of building and operating a 335 MW Integrated Gasification Combined Cycle (IGCC) power plant as well as the commercialization of its technology.

  6. The Next Generation In Water Filtration For The Oil And Gas Industry
    4/17/2013

    There is a need in many segments of the oil and gas production industry for an improvement in water filtration over traditional methods. By Michael Dejak, P.Eng. 

  7. FGD Purge Treatment In Coal-Fired Power Generation
    3/6/2015

    Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.

    These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.

  8. Meter Technology Used For Verification
    11/13/2015

    The core of Coriolis mass flowmeters are oscillating tubes. As soon as mass is flowing through them, a Coriolis force is affecting the oscillation, creating a phase shift.

  9. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  10. Natural Gas Fractionation Process Facilities Rely On Flow Switch For Relief Valve Leak Monitoring
    12/2/2017

    A company with multiple natural gas liquid (NGL) fractionation process facilities located in the Southeastern U.S became concerned about a series of missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief valves. The company wanted a highly reliable flow instrument solution that would detect a real event and avoid the lost productivity of nuisance alarms.
