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?

Automatic pH Balancing Systems Automatic pH Balancing Systems

ClearBlu builds package pH balancing systems for high strength wastewater that are robust and low maintenance.  High strength strength wastewater can easily blind pH sensors, even when they are insertion mounted in a pipe.  ClearBlu utilizes digital self-cleaning immersion sensors for reliability, longer periods between calibration and lower chemical usage.

Radial Jet Pod Aerators Radial Jet Pod Aerators
The Mass Transfer Systems radial jet pod aerators are designed with jet aeration nozzles installed around the circumference of an integral liquid / air pod body. This configuration is most applicable for smaller round and square tanks and sequence batch reactors where directional flow patterns are not desirable.
1500 Series For Cost-conscious Municipal and Industrial Water Markets 1500 Series For Cost-conscious Municipal and Industrial Water Markets

EPDM elastomers’ fully saturated backbone lends these diffusers superb resistance to ozone and oxygen, while its non-polar nature provides resistance to ketones and alcohols. These economical membranes also offer excellent chemical, heat, acid and phosphate fluid resistance. With good low temperature flexibility, this series’ technology provides optimum performance and stability over a broad range of operating temperatures. Our Columbus, Drake and Magellan membrane technology is not recommended for applications where petroleum or mineral oils, or di-ester lubricants are present.

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.
