Waterschap Brabantse Delta (NL) - Case Study
For two sewage treatment plants of Dutch water board “Brabantse Delta”, Landustrie supplies 3 no. brush aerators, also called aeration rotors. Unique here is the design of the aeration units. Normally the brush aerators are fixed mounted between the side walls of an aeration ...

Aerators Enhance Aerobic Digestion Process
The city of Eden,N.C.,operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l. This high biomass concentration is necessary to provide a well-settling sludge and good effluent quality. Further, the plant influent is approximately 40% domestic wastewater and 60% industrial ...

Floating Horizontal Aerators Enhance Eufaula, Alabama Activated Sludge Plant
The Eufaula, Alabama, wastewater treatment plant (WWTP) is an extended aeration activated sludge facility designed for an average daily flow rate of 2.7 million gallons per day (mgd). Prior to February, 2005 this WWTP used vertical aerators to provide oxygen and mixing in its aerator basins. The plant has two aeration basins, each 1.87 million gallons in volume, which had 160 horsepower (hp) of ...

Performance of mechanical aerator in wastewater treatment with special reference to oxidation ditch: a critical review
Mechanical aerators used in wastewater treatment are the largest energy consumers in biological reactors. Well-known researchers have been working on the oxygen transfer by mechanical aerators in oxidation ditch process and they have successfully enhanced the efficiency of aeration system with considering the factors affecting oxygen transfer such as speed of rotors and geometry of aeration ...

Why does modern aeration technology make the treasurer happy?
The aerzen combined system provides optimum efficiencies at the wallau wastewater treatment plant The combination of different technologies for air conveying enablesoptimal energy use of oxygen for biological degradation processes in wastewater treatment plants. Concrete savings resulting from the use of AERZEN machines demonstrate this in practice at the Wallau plant. In 2016, the ...

Controlling Aeration Bioaerosols
Aeration of wastewater can cause pathogens to go airborne, but the right choice of aerator can minimize the danger During wastewater treatment, an adequate disinfection stage kills virtually all bacteria and viruses that might be harmful the public, agriculture, and ecosystems before effluent is discharged or reused. But disinfection is generally the final stage of treatment, so when wastewater ...

Performance of Floating Horizontal Aerators in Aerated Lagoons and Oxidation Ditches
INTRODUCTION When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and ...
