Aeration & Blowers Resources

51. Abbottstown Retrofitted A Flow-Through System With An AquaSBR® System To Meet Stringent Effluent Requirements 4/9/2020

    The Abbottstown-Paradise Joint Sewer Authority was incorporated in 1973 and utilized a continuous flow activated sludge system with an average daily design flow of 0.21 MGD. At that time the plant was only required to reduce total suspended solids (TSS) and effuent ammonia to required levels to serve the area population of about 2000. Due to urban growth and increased storm flow runoffs, the plant was in need of an expansion and upgrade by the late 1990s. 

52. HST™ Turbocompressor For Sky-High Savings In Wastewater Treatment 4/1/2020

    The town of Fraser, Colorado, USA, with an annual mean temperature of 32.5°F is the coldest town in the lower 48 states and gets frost year-round. At an elevation of 8’574 feet, it is also the highest location for Sulzer’s HST 20 turbocompressor in the world. The Fraser WWTP high-speed blower upgrade was completed in early 2019, replacing older centrifugal blowers, which were loud and costly to operate.

53. HST Turbocompressor Survives Category 4 Hurricane 4/1/2020

    Victoria, Texas, is a small South Texas town of approx. 65’000 people just 30 miles inland from the Gulf of Mexico. This area is considered as humid subtropical, and the temperatures regularly exceed 100°F for the months of June through August. A record high temperature of 111°F was recorded in September 2000 and a record low of 9°F in December 1989. This location displays one of the most extreme temperature differentials in the United States. The HST high-speed blower was used in the new plant design which replaced an older two-stage trickling filter design in the Victoria WWTP.

54. Refinery Treats Groundwater Contamination While Saving Precious Facility Space 3/20/2020

    A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant.

55. Olathe, KS Cedar Creek Plant Boasts The First In-Line Fermenter In The Country 2/17/2020

    The City of Olathe is located just outside of Kansas City and is home to a growing population of 126,000, making Olathe the fifth most populous city in Kansas. Residents depend on the local Cedar Creek Wastewater Treatment Plant (WWTP) to meet their water demand.

56. A Model Integration Of State-Of-The-Art Technologies That Satisfied Both Initial And Long-Term Considerations 2/17/2020

    The surrounding areas of Rock Creek Public Sewer District of Jefferson County, Missouri experienced substantial development in recent years overloading existing privately owned wastewater plant capacities.

57. SBR System Boosts Capacity, Reliability Without Building A New Facility 2/17/2020

    Jefferson City, Missouri utilized a Sanitaire SBR System to meet current needs and allow for peak flow rates.

58. Technologies To Meet Smaller Footprint And Stringent Nitrogen And Phosphorous Requirements 2/5/2020

    The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.

59. Cuxhaven Treatment Plant Reduces Aeration Energy Use By 30% While Ensuring Effluent Water Quality Compliance 1/31/2020

    As a proactive wastewater treatment operator, EWE wanted a system to optimize the energy consumption associated with aeration and improve safety with better system control of chemical usage. 

60. Seeking Versatility And Simplicity In Troy, Alabama 10/30/2019

    Troy Alabama’s Wastewater Treatment Plant was faced with broken discs causing dropping dissolved oxygen (DO) levels in their oxidation ditch. The 3.5 mgd plant opened in 1979. In 1992-1993, a disc rotor system was installed. After 23 years of service, the discs started breaking. Dave Fiveash, Troy’s Plant Manager for the past 21 years, was driven to find a solution to keep the plant operating and meeting DO requirements.
