Headworks Improvements Resulted In Significant Reduction Of Maintenance
Headworks Improvements Resulted In Significant Reduction Of Maintenance

Previously the crew at Payson WWTP wrestled with clogs that required constant attention and increased system downtimes. With the installation of the new headworks, the comparison was stark because suddenly the flow from the headworks was debris-free.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  • Carbon Dioxide For pH Control Of Landfill Leachate
    Carbon Dioxide For pH Control Of Landfill Leachate

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  • In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.

  • Time-Tested Technology: 25 Years of Trickling Filter Media Success
    Time-Tested Technology: 25 Years of Trickling Filter Media Success

    The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.

  • Building A Flexible Non-Proprietary SCADA System

    In 2008, Chatham County Public Works was using three different SCADA systems to monitor and control their remote tanks and pump stations. One was a sole-source software and hardware solution that used a unique communication protocol. By Christopher Little, Daniel Clevenger and Kevin Monk

  • Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations
    Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations

    Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.

  • Ultrasonic Flow Measurement System Saves WWTP $72,500 Annually
    Ultrasonic Flow Measurement System Saves WWTP $72,500 Annually

    If the wastewater treatment plant serving Reading, PA, and 11 surrounding municipalities has a mission statement for its day-to-day operations, it couldn’t be simpler or more critical: “95°F.”

  • Pipe Repair: Emergency Response In Compton
    Pipe Repair: Emergency Response In Compton

    When the Sanitation Districts of Los Angeles County (LACSD) were formed in the 1920s, the agency embarked on its first major project -- the construction of the backbone trunk sewer of the Joint Outfall System (JOS). Since then, the Sanitation Districts have completed many challenging projects, providing environmentally sound, cost-effective wastewater and solid waste management services to over five million people in Los Angeles County.
