A Cost-Effective Approach To Aeration Optimization A Cost-Effective Approach To Aeration Optimization

The need for water utilities to update aging infrastructure and meet emerging challenges has reached a critical point across the country, but investing in solutions typically costs more than most municipalities can afford. The good news is that advanced aeration technology is available to optimize existing infrastructure at lower costs than major modifications or new construction.

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.
