The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

Aerobic Treatment Of Wastewater For Fish Flour And Fish Oil Company Reuse
Aerobic Treatment Of Wastewater For Fish Flour And Fish Oil Company Reuse

A fish flour and fish oil processing company produces 100 tons of flour a day from fish waste resulting from the broth concentration plant and from drying of flour, washing water, boiler blowdown and cooling towers. The company needed to treat its wastewater and to reduce its water supply costs.

Fine bubble membrane disc aeration has been significantly improved by the group of Aquarius engineers who bring decades of aeration experience to the market.

MicroShield Technology MicroShield Technology

Our diffusers can last upwards of 10 years. It isn’t science fiction. It’s simply science, multiplied by our MicroShield Technology to protect against degradation.

TWISTER® Low-Speed Aerator TWISTER® Low-Speed Aerator

Long-lasting performance, and the highest oxygen-transfer rates of any mechanical aeration system on the market.

OX™ Disc Aerators OX™ Disc Aerators

The bigger and completely redesigned OX™ disc aerator doubles the amount of oxygen transferred by the original Orbal® system disc aerator. This means that the same amount of oxygen can now be delivered with fewer discs, which reduces maintenance, construction and capital costs. It also allows facilities with existing Orbal systems to increase capacity if they replace their existing discs with new OX disc aerators.

SmartAerator™ TORNADO® SmartAerator™ TORNADO®

Complete energy saving aeration solution for municipal and industrial wastewater treatment. The SmartAerator provides up to 50% annual energy savings for wastewater treatment facilities. Ideal projects are those that require large horsepower aerators and projects with multiple aerators where energy savings would be significant.

Often times the biosolids management portion of the treatment plant may not be optimized, resulting in inefficient operation of the entire treatment plant. For instance, did you know that aerobic digestion is the second largest consumer of energy after biological treatment aeration at a wastewater treatment plant? Or, do you realize that up to 50% of the nutrient loading on any given day may be coming from the biosolids process?

Discussing the projects that RWL Water has been involved with in 2016, you understand just how variable the world of water treatment really is.

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.
