Aeration & Blowers Resources

81. History Made With New Aeration System 7/23/2018

    The challenge for Sulzer was to prove that the new products are even better than the reliable and proven components previously used in two aeration basins of the new Pulawy wastewater treatment plant in Poland.

82. Aerobic Treatment Of Wastewater For Fish Flour And Fish Oil Company Reuse 6/29/2018

    A fish flour and fish oil processing company produces 100 tons of flour a day from fish waste resulting from the broth concentration plant and from drying of flour, washing water, boiler blowdown and cooling towers. The company needed to treat its wastewater and to reduce its water supply costs.

83. BIOSTYR® Improves Health Of The Long Island Sound 6/13/2018

    The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

84. CAGI Data Sheets: Blower Performance Comparison Technical White Paper 2/13/2018

    Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

85. MABR Is The Big Cheese For This Dairy Farming WWTP 1/29/2018

    Hayogev is a residential development in the rural area of Jezreel Valley, with 1000 homes, agricultural fields and dairy farms. Located in an open field next to small farms, the local treatment facility handles wastewater from HaYogev and Midrach Oz. The customer was looking for a localized wastewater treatment solution to replace the existing pond system, which faced difficulties in treating the wastewater due to high levels of nutrients. A new state-level regulation concerning reclaimed water required the wastewater treatment plant (WWTP) operator to reduce the nutrients in the effluent stream. The solution had to be odorless and quiet, have low power consumption, and use the existing pond and structure.

86. Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits 11/9/2017

    The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve their effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate.

87. Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency 11/9/2017

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

88. The Evolution Of High Speed Turbo In The Wastewater Industry 11/3/2017

    High speed turbo (HST) technology was the most quickly adopted blower design to enter the U.S. wastewater market.  HST appeared in 2006, at a time when there was a need for more efficient plant operation. 

89. 10 Water-Tech Winners From WEFTEC 2017 10/25/2017

    For the second straight year, the Water Environment Federation Exhibition and Conference (WEFTEC) came to McCormick Place in Chicago, returning also to the city which launched WEFTEC 90 years ago. As always, it was a showcase of the latest technologies and ideas available in the water/wastewater industry, but each show also has its own "feel" that reflects the times.

90. The Proper Application Of Rotary Lobe And Rotary Screw Blower Technology 9/28/2017

    Written by Kaeser’s system experts, this white paper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.
