AERATION & BLOWERS RESOURCES

  • Municipality Looks To Expand Plant Capacity While Reusing Existing Systems

    Sharjah Municipality of the Untied Arab Emirates (U.A.E.) was requiring to treat more and more flow despite having very little space for new treatment systems. They were looking at wanting to expand their plants No. 4 & No. 5 plants to meet new total nitrogen limits and try to do so by having to reuse the existing systems. This type of upgrade would save on cost as well as space at the plant.

  • IFAS System Produces High Quality Effluent In East Central Kansas

    The City of Emporia, in East Central Kansas, recently experienced an increase in population and more stringent effluent permit requirements resulting in a strained wastewater treatment plant. Emporia retained the services of a local engineering firm to evaluate the current and future needs of the system and recommend an economical, sustainable, and effective solution. After evaluating several options, World Water Works’ Integrated Fixed Film Activated Sludge (IFAS) conformed to all the requirements and was selected.

  • Treating Food Wastewater Efficiently Using Jet Aeration

    Food processing is a water-intensive process, and its wastewater byproduct is typically high in volumetric daily flow and also biochemical and chemical oxygen demand (BOD and COD), organics, and nutrients. Consequently, significant on-site treatment and resources are necessary.

  • Memorial Park Pump Station, Tauranga City Council

    The Memorial Park Pump Station (MPPS) transfers wastewater flows from Memorial Park to Chapel Street WWTP and/or Te Maunga WWTP. It is a large pump station (PS) installed within a 9.0m diameter concrete structure. The pump station is approximately 12m deep, with a 6.5m maximum water depth and split into several compartments.

  • Reducing H2S And FOG At The Discharge Of A Force Main

    Beginning early in 2019 our office began receiving complaints of sewer odor in the neighborhood of Fountain Ridge Section III (FR III), located in Prince George County VA. The County Operations staff investigated the wastewater collection system that serves the neighborhood, and found that odor was proliferating throughout the neighborhood. Corrosion of the sewer manholes was clearly evident.

  • CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility

    For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.

  • New Turbocompressors Boost Efficiency At Wastewater Plant

    Sulzer engineers helped a plant in the Netherlands cut its energy costs with a turnkey project

  • Mixing Made Easy For Low Energy Lakes, Ponds, And Lagoons

    Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind. Neither of these natural mixing sources is sufficient to allow shallow water bodies to respire and deal with the natural biological degradation of wastes and detritus that eventually form on the bottom. Eventually, external problems will occur – algae begins to form in abundance, odors will emanate from the water due to stagnation, blue-green cyanobacteria will form on the surface and cause more odor and toxicity, and eventually the water is no longer capable of supporting basic aquatic fauna reproduction.

  • Leveraging Rentals For Pneumatic Conveying Applications

    Pneumatic conveying applications are critical to many facilities – when you can’t move material you can’t make or sell your product. Because of a historical lack of availability of specialized rental blowers and compressors for pneumatic conveying, plants often ether accepted the production outage or rented a more readily available 2 stage oil-free rotary screw compressor designed for 90-150 PSIG plant air service that is very inefficient at the reduced pressures needed for pneumatic conveying.

  • Saving The Most Money On Wastewater Aeration: Bringing It All Together

    The power required for aeration is 50 to 60 percent of the electric bill for a municipal wastewater plant, sometimes accounting for up to 4 percent of the associated community’s total power. Energy efficiency is a critical factor in evaluating blower performance.

WASTEWATER AERATION SOLUTIONS

  • Aeration Works Division The Aeration Works Division was created to give operators of aeration systems a source for fast, reliable installations and maintenance. Made up of experienced installers and field service professionals, the Aeration Works Division are experts at the installation and maintenance of EDI aeration systems.
  • Bi-Directional Jet Aerators Mass Transfer Systems bi-directional jet aerators are designed with jet aeration nozzles installed on both sides of the liquid/air jet aeration manifold. This configuration is most applicable for square or rectangular tanks, larger lagoons, and sequence batch reactors where directional flow patterns are not desired.
  • UNOX™ Process Upgrade

    Praxair has had an extensive history of innovation in the wastewater treatment process. About 15% of all wastewater treatment in the United States occurs in UNOX™ type systems. Since their original construction, many facilities now require adherence to new regulations. Praxair can help you make the required changes to ensure that your facility is running in the most efficient way possible and in line with current standards. We provide a wide range of technologies for UNOX™ facilities. These include enhancements that can help you achieve reduced operating costs and improved reliability through the upgrade of oxygen generation and dissolution equipment.
