Wastewater Treatment Case Studies and White Papers

  1. Energy-Efficiency Showdown: A Comparison Of Aeration Technologies
    11/18/2013

    On paper and in practice, aeration options and their corresponding efficiencies are calculated and compared.

  2. Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test
    9/25/2018

    In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

  3. Z-88® Radium Treatment Process - City Of New Underwood, South Dakota Case Study
    8/9/2012

    This radium removal pilot study was conducted for the City of New Underwood, South Dakota. New Underwood’s water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).

  4. Understanding The PeriFilter Technology
    8/15/2013

    There is a newly-developed technology, the so-called PeriFilter® that will hit the market within the next few weeks. This offers many heretofore technological and economic advantages in the separation of solid phases from liquid phases with concomitant transformation of the solid phases into processable forms for further usage and/or products.  It may be used in the separation of solids from liquids in water purification and in wastewater treatment applications as well.

  5. Green Slime Plagues Florida, Drives Home Importance Of Nutient Removal
    7/31/2016

    While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.

  6. Monster Clears Clogs And Streamlines Septage Delivery At Ventura Regional Sanitation District
    1/21/2015

    The Ventura Regional Sanitation District’s Liquid Waste Treatment Facility (LWTF) was experiencing a double-threat to safety and productivity.

  7. Freeport Wastewater Treatment Plant Saves Money And Energy With Hybrid Blowers
    9/30/2013

    Best known as the home of outdoor retailer L.L. Bean, the community of Freeport is a popular summer destination on the shore of Casco Bay in southern coastal Maine. In 2010, the Freeport Sewer District brought in engineering firm Woodard & Curran (also of Freeport), to conduct an energy analysis of the Freeport Wastewater Treatment Facility. The assessment revealed that the Freeport plant consumed more than 8.9 kBtu per gallon of wastewater treated, more than double the national average of 4.1 kBtu per gallon. While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80 percent of the electricity consumption.

  8. Complete Blower Package Results In Quiet Operation, Easy Maintenance
    9/21/2016

    Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

  9. 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.

  10. 10 Fluid Measurement Plant Imperatives That Increase Process Efficiency And Reduce Costs
    1/1/2018

    Accurately measuring the flow and level of the various liquids and gases that travel through a process industry plant is a critical function for effective and efficient plant operations. Read more to learn ten important industrial process plant functions that can benefit from accurate, repeatable and reliable electronic flow or level measurement.
