WASTEWATER AERATION & BLOWERS WHITE PAPERS AND CASE STUDIES

Packaged Wastewater Treatment For Uneven Terrain
Packaged Wastewater Treatment For Uneven Terrain

Storey County, NV, just southeast of Reno, needed to replace an outdated wastewater treatment plant that serves the historic communities of Virginia City and Gold Hill. The new site was on the side of a hill, presenting challenges for the design of the plant and the orientation of its processes. Also, the new plant area was entirely within a district on the National Register of Historic Places. Read the full case study to learn how the new modular design allows for an efficient wastewater treatment solution.

Mounting S&N's unique rotor on an adjustable floating platform insures optimum operating depth for maximum mixing and oxygen transfer
Sanitaire Ceramic Disc Fine Bubble Aeration Systems by Xylem Sanitaire Ceramic Disc Fine Bubble Aeration Systems by Xylem

Sanitaire fine bubble ceramic disc aeration systems incorporate superior and advanced engineering features in the ceramic element, the diffuser sealing method and the piping system joints and supports. The premier line of SANITAIRE fine bubble ceramic disc diffusers is considered the most efficient technology available for oxygen transfer in wastewater treatment applications.

Directional Jet Manifold Aerators 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.
OxyStream™ Oxidation Ditch OxyStream™ Oxidation Ditch

The OxyStream™ Oxidation Ditch from WesTech Engineering has proven to be the ideal equipment for biological wastewater treatment applications throughout the world. It combines vertically mounted, low-speed surface aerators with an oxidation ditch design to maximize oxygen transfer efficiency while maintaining the greatest flexibility for power turndown. In addition, the OxyStream™ has greater side water depths and fewer required aerators than a conventional brush rotor or disc rotor oxidation ditch. The vertical slow-speed surface aerator eliminates maintenance-prone horizontal shafts, pillow block bearings, and drive units near the water surface. Above all, the OxyStream™ Oxidation Ditch provides energy savings and produces predictable, high-quality effluent.

Three Largest Challenges With Wastewater Lagoons Three Largest Challenges With Wastewater Lagoons

When it comes to wastewater lagoons, there are three main challenges that operators run into. The first, similar to other parts of the nation’s wastewater treatment infrastructure, is age. The second is compliance with new EPA ammonia, nitrogen and phosphorus limits which many lagoon plants weren’t designed to deal with. And the third is expansion as communities grow and need additional capacity.

Enhanced Primary Treatment Reduces Energy By Separating BOD Before Aeration Enhanced Primary Treatment Reduces Energy By Separating BOD Before Aeration

At WEFTEC 2016, Evoqua Water Technologies explored six core challenges faced by wastewater treatment plants -- energy reduction, nutrient removal, odor and corrosion control, aging plant equipment, water reuse and disinfection. In this Water Online Radio interview, Paul Rice, Municipal Marketing Director with Evoqua Water Technologies, discusses energy reduction and nutrient removal in more detail.

Energy Efficiency Boosted By Replacing Controls Not Blowers Energy Efficiency Boosted By Replacing Controls Not Blowers

At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.

ABOUT AERATION

 

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.
