Aeration & Blowers White Papers And Case Studies

  1. A Small Town With Big Challenges
    11/14/2016

    Aqua America water treatment plant in Tiffin, Ohio, was built in the 1920s and is situated on the Sandusky River. The plant processes 3.4 million gallons per day and was facing challenges of producing high-quality drinking water. A full measure of seasonal variety, combined with the runoff from a thriving agricultural environment, caused the small-town water facility to constantly encounter adverse conditions. In an effort to remain compliant, Aqua America enhanced coagulation, but this increased sedimentation rates and exacerbated sludge blanket depths.

  2. Meeting Stringent Discharge Levels With AccuFAS
    11/14/2016

    When the Coldwater Board of Public Utilities in Coldwater, Michigan abruptly received new ammonia permit limits in August of 2007, they hired consultants to help guide them to the best solution for their new problem. With a full‐measure of influent waste variety consisting of residential, commercial, industrial and septage and a new seasonal permit limit of 2mg/L, Coldwater hoped for a budget friendly solution to consistently perform through peak flows and industrial shockloading.

  3. Smooth Operator
    10/31/2016

    All turbo manufacturers are not created equal. After a different supplier failed to perform, Aerzen’s technology, expertise, and customer service took the Charles River WWTP from extreme frustration to smooth operation.

  4. Improving Total Nitrogen Removal
    10/21/2016

    To protect the sensitive waters of the Neuse River Basin, the State of North Carolina formally adopted a nutrient management strategy in 1997 which established Total Maximum Daily Loads for all point source contributors of Total Nitrogen (TN) to the Neuse River. By upgrading its oxidation ditches, this Eastern NC plant saw a reduction of 76% TN compared to its average discharge from the past 6 years.

  5. Quality Effluent: BIO-DENITRO™ + Hydrotech Discfilter
    10/18/2016

    In order to meet the demand of growth within the city and to achieve stringent effluent limits, the City of Sanford worked with CPH Engineers to design the Sanford South Water Resource Center (WRC), located in the heart of Central Florida. The facility produces a high quality effluent of reclaimed water standards, which is distributed throughout the region.

  6. 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.

  7. In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    6/16/2016

    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.

  8. AquaSBR System Installed To Increase Capacity In A Small Footprint
    6/9/2016

    The West Central Conservancy District (WCCD), located in Hendricks County, IN, was formed to resolve sewer issues that the service area was experiencing with the local utilities company in the mid- ’80s.

  9. WWTF Receives EPA Award For Achieving Low Level Nutrient Limits
    6/9/2016

    Lee Wastewater Treatment Facility (WWTF), located in Massachusetts, received an award for its excellent treatment performance in 2012 from the Environmental Protection Agency (EPA), 4 years after start-up.

  10. Innovative Use Of Dissolved Air Flotation With Biosorption As Primary Treatment To Approach Energy Neutrality In WWTP’s
    6/1/2016

    This paper presents two types of DAF applications together with biosorption (the “Captivator system”) as primary treatments. In one case, the Captivator system is the sole primary treatment for a new plant installation and helps to gain 65 percent more biogas while requiring only 44 percent of aeration for COD oxidation, compared to a conventional process.
