Wastewater Treatment Case Studies and White Papers

  1. Centerfeed Fine Screen Dramatically Increases Throughput

    The Rotamat screen has been a popular choice for protecting debris sensitive technologies downstream such as MBRs. Through a constant program of responding industry needs, Huber Technology has developed the RPPS Star Pro series centerfeed fine screen. When combined, the Star and Pro options for the RPPS increases capacity and enables for even finer perforations, allowing for increased screenings removal in a tighter footprint.

  2. Pulp And Paper Manufacturer Significantly Increases Production While Complying With Discharge Limitations

    A U.S.-based pulp and paper manufacturer required high purity process and boiler feed water. It was using water from a local well and treating it with a 150 gpm conventional RO system operating at 75% recovery, but this was creating 50 gpm of wastewater – over 26 million gallons per year.

  3. Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

    There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

  4. Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations

    Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

  5. Water Level Concerns In Texas Require A Stable Solution

    The Sabine River Authority (SRA) operates the 36,700 surface-acre reservoir of Lake Tawakoni and Iron Bridge Dam on the headwaters of the Sabine River. A number of historic Indian tribes settled in the surrounding land area prior to construction of the reservoir in 1960, giving Lake Tawakoni its name. By The Gorman-Rupp Company

  6. Kirin Beer Uses 3M Liqui-Cel Membrane Contactors For CO2 and O2 Removal to Prevent Pipe Corrosion at Three of Their Japanese Breweries

    In the food and beverage industry, there is a growing awareness of environmental considerations wherever chemicals are used. In response, companies are trending towards alternative systems that operate with less chemical usage.

  7. Dependable Operation And Longevity Invaluable To Guelph’s Screening Process

    It had become obvious to The City of Guelph that it was time to replace several of the components in its treatment process. Project leaders wanted to upgrade its treatment processes by implementing leading edge technology. By thoroughly researching what was available they choose the technology and vendor that was the best match for their long-term wastewater treatment goals of the City.

  8. Supplemental Aeration System Reduces High BOD Levels And Solves Odor Issues

    A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant.

  9. Are Test Strips Still Relevant For Water Analysis?

    Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?

  10. Louisiana Wastewater Treatment Facility Benefits From Siemens Product Support

    A municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
