Aeration & Blowers Resources

81. Post-Treatment Aeration Maintains Dissolved Oxygen In Effluent High-Solids Wastewater Prior To River Discharge 8/17/2018

    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.

82. Aeration System Solves Lagoon Odors And High Maintenance Problems 8/15/2018

    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.

83. Activated Sludge Treatment In A Municipal Sewage Treatment Plant 8/1/2018

    A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP that was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. Read the full case study to discover how Mazzei solved the problem.

84. 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.

85. 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.

86. 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.

87. 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.

88. 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.

89. Aeration System Prevents Septic Conditions 1/11/2018

    Circa 2010, Carollo Engineering designed and implemented expansions at wastewater treatment plants in Delano, California and Reedley, California to handle increased flows of up to 8.8 MGD and 5.0 MGD respectively. The proposals for both facilities specified a need for storage and processing of secondary sludge produced by the processes’ secondary clarifiers. Mazzei Injectors were selected to provide an efficient, zero maintenance method of freshening and mixing the sludge. Read the full case study to learn more.

90. 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.
