Wastewater Treatment Case Studies and White Papers

  1. Picking The Perfect Pump

    Pumps and pumping systems are like unsung heroes of modern society – quickly and quietly transporting vital water supplies, chemicals and waste to and from locations, which rely upon their consistent, reliable operation.

  2. Tradeshow Technical Session Leads To Significant Reduction In Polymer Use For South Carolina WWTP

    Greer Commission of Public Works (CPW) has been providing water, wastewater and electric services to the City since 1914 with natural gas service added in 1957.

  3. Evaluating Different Blower Technologies On A Wire-To-Air Basis

    In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove. By Andrew Balberg

  4. Disc Thickener Technology Becomes Essential Key Component In Process

    BCR Environmental utilizes the Huber Technology S-Disc thickener in their sludge neutralization process. Because the system is both simple and reliable they chose to standardize on the S-Disc. The design of the technology enables the operators easy access to monitor their process. Read how BCR is putting the S-Disc to work.

  5. Wastewater Plant Cuts Mechanical Aeration Run Time With Solar-Powered Circulation Technology
    In the Buckeye State, the village of St. Henry, OH, is bucking the trend of many rural farming communities. Instead of losing residents and local businesses to bigger cities, this community is growing. Local industries such as turkey processing are expanding as well. By: Michael Christensen, SolarBee, Inc.
  6. Gas Transfer: Theory And Key Process Factors

    This paper discusses gas transfer theory and key factors of the process along with sample applications using the Dif-JetTM including; transfer of CO2 gas for pH neutralization of wastewater, for aeration and oxygenation, and for disinfection using ozone.

  7. Article: Floating Horizontal Aerators Enhance Eufaula, Alabama Activated Sludge Plant
    The Eufaula, Alabama, wastewater treatment plant (WWTP) is an extended aeration activated sludge facility designed for an average daily flow rate of 2.7 million gallons per day (mgd). Prior to February, 2005 this WWTP used vertical aerators to provide oxygen and mixing in its aerator basins. The plant has two aeration basins, each 1.87 million gallons in volume, which had 160 horsepower (hp) of vertical aerators in each basin
  8. Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker

    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.

  9. Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits

    Prior to 2007, Concord, Massachusetts wastewater treatment plant operated under a NPDES permit that allowed a seasonal phosphorus limit of 0.7 mg/L. But with the issuance of a new five-year permit with a phosphorus limit of 0.2 mg/L and the probability that future limits could reach as low as 0.05 mg/L, Concord needed a treatment solution that would be reliable and cost-effective today and over the long term.

  10. Trinity River Authority Increases Filtration Capacity And Decreases Backwash With AquaDiamond® Cloth Media Filters By Aqua-Aerobic Systems

    The Trinity River Authority (TRA) of Texas established its Central Regional Wastewater System (CRWS) in 1957 and began operations in December 1959.
