Aeration & Blowers White Papers And Case Studies

  1. Packaged Wastewater Treatment For Uneven Terrain
    7/31/2017

    Storey County, NV, just southeast of Reno, needed to replace an outdated wastewater treatment plant that serves the historic communities of Virginia City and Gold Hill. The new site was on the side of a hill, presenting challenges for the design of the plant and the orientation of its processes. Also, the new plant area was entirely within a district on the National Register of Historic Places. Read the full case study to learn how the new modular design allows for an efficient wastewater treatment solution.

  2. Blower System Integration For Wastewater Aeration Applications
    7/27/2017

    The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

  3. Use Of Pure Oxygen To Resolve Capacity And Odor Problems
    7/27/2017

    The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

  4. Affordable Wastewater Collection And Treatment
    7/26/2017

    A modern, master-planned community in the Texas Hill Country needed an affordable wastewater collection and treatment system that could be installed in phases and would perform as reliably as a large municipal system but without the cost, odor, or need for a full-time operator.

  5. Pure Oxygen Injection Into A Pipeline
    5/4/2017

    The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

  6. Supplemental Aeration System Reduces High BOD Levels And Solves Odor Issues
    5/4/2017

    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. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.

  7. Post-treatment Aeration Maintains Dissolved Oxygen In Effluent High-Solids Wastewater Prior To River Discharge
    5/4/2017

    The LeSourdsville WWTP in Butler County, Ohio, was required to meet their NPDES permit requirement of 6 mg/l dissolved oxygen at the plants Miami River outfall.

  8. Aeration System Solves Odor And Nutrient Problems For Carrot Packing Plant
    5/3/2017

    A carrot packing plant was having severe odor problems due to septic conditions in their truck washout water holding lagoon. In addition, nutrient and nitrogen levels were becoming an issue for land application of the wastewater for crop production.

  9. In-line Aeration System Provides Required Level Of Dissolved Oxygen In Pressurized Effluent Line
    5/3/2017

    The treated effluent from all wastewater treatment plants across the country must meet local dissolved oxygen (DO) limits before discharging into receiving waters.

  10. Aeration System Solves Lagoon Odors And High Maintenance Problems
    5/1/2017

    A large vegetable processing facility was experiencing problems with its lagoon surface aerators. The company’s treatment process includes a collection and screening assembly, two anaerobic stabilization ponds and a 40 million gallon aerated lagoon.
