Aeration & Blowers White Papers And Case Studies

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. Pulp and Paper Mill Finds Solution To Improve Onsite Lagoons
    5/23/2016

    Pronal, a recycled paper plant, produces craft paper. The plant produces an average flow of 14,000 m3/day (3.7 MGD) of wastewater with high contents of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS).

  9. Submersible Pumps Help With Flood Control
    5/1/2016

    Sims Bayou begins near Missouri City, TX, and meanders northeast until it reaches Buffalo Bayou.

  10. Switch To Hybrid Blowers Offsets 68% Electrical Rate Increase For WWTP
    3/2/2016

    The Old Orchard Beach Wastewater Treatment Plant (WWTP) serves the town of Old Orchard Beach, Maine, a coastal resort community where the population swells from 9,000 year-round residents to 75,000 in late June through early August, when seasonal residents and day trippers descend for the peak summer months.
