Wastewater - Aeration

Supplemental Aeration System Reduces High BOD Levels And Solves Odor Issues A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. By Mazzei Injector Company, LLC
The Re-Habilitation Of 43 Year Old Waste Lagoons In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. By Dale Klussman
Sewer Authority Ends Plant Bypasses And Introduces Nutrient Removal With New Treatment Process
The original contact stabilization activated sludge process at the Portage Area Sewer Authority generated hydraulic limitations that required repeated bypasses during heavy rainfall. Find out how the treatment plant upgraded its secondary treatment aeration system to include nutrient removal through a nitrification/denitrification/phosphorus process and has successfully processed I&I induced surges that reached a 10-MGD peak.
Fine Bubble Aeration System Reduces Power Consumption, Saves Money
With significant increases in production, the static tube aeration system at F&A Dairy was unable to deliver sufficient oxygen to the lagoon treatment system. By Environmental Dynamics International
Meeting State Nutrient Regulations With SBRs
After the Missouri Department of Natural Resources reclassified the effluent receiving stream in the city of Sullivan, officials learned that its wastewater treatment lagoon required a more advanced treatment process to comply. They selected a continuous-flow sequencing batch reactor (SBR) system that utilizes a modified activated sludge biological treatment. The new infrastructure has provided cost-saving results for the ongoing removal of nitrogen and phosphorous.

Directional Jet Manifold Aerators

The Mass Transfer Systems directional jet aerators are designed with jet aeration nozzles installed on only side of the liquid / air jet aeration manifold. This configuration is most applicable for round tanks, lagoons, and ditches where directional flow patterns can be achieved to aid in the mixing of the tank contents.

Aeration: Aire-O<sub>2</sub> TRITON® Process Aerator/Mixer

Aeration: Aire-O₂ TRITON® Process Aerator/Mixer

With the AIRE-O₂ TRITON® Process Aeration And Mixing, biological nutrient removal (BNR) is now easier and more cost effective by combining mixing, aeration and BNR in a single compact unit with separate on/off modes. And, the Triton's proprietary engineered propeller/diffuser result in higher oxygen transfer and greater mixing capabilities to 33 feet (10 meters) deep! Low speed (900 rpm/60Hz - 750 rpm/50Hz) operation extends aerator life and ensures quiet operation. Together with our AIRE-O2 aspirator aerator, more than 60,000 aeration units delivered worldwide since 1974.

VARI-CANT® Jet Aeration Systems

Our VARI-CANT® jet aeration systems utilize proven principles of jet aeration, combined with state-of-the-art design and materials, resulting in a system with superior performance, efficiency and trouble-free operation.

The VARI-CANT® jet aeration system intermixes air with a motive liquid and injects the stream into the wastewater. The aerator itself consists of two jet nozzles. The motive liquid - recirculated mixed liquor is discharged from an inner nozzle into an outer mixing nozzle . Compressed atmospheric air is introduced, and sheared into tiny bubbles which are entrained in the motive liquid stream. As the stream is discharged into the surrounding mixed liquor, it forms a highly turbulent jet plume. The plume entrains the surrounding mixed liquor and brings it into contact with the tiny air bubbles, resulting in a extremely high oxygen transfer rate.

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
