Exploring aeration-associated energy savings at a conventional water reclamation plant
Aeration accounts for a large fraction of energy consumption at conventional water reclamation plants (WRPs). Older plants were designed when control techniques were relatively primitive and energy consumption was less of a concern. As a result, although process operations at older WRPs can satisfy effluent permit requirements, they can operate with excess aeration. In this study, we ...

Industrial Pond Treatment
This small municipality was experiencing difficulty in maintaining dissolved oxygen levels in their industrial ponds. During the processing season, they were receiving 3MGD of industrial wastewater from tomato and green pepper processors. During the previous season, they had been out of compliance on numerous occasions and received several complaints from the public concerning odors from the ...

Modelling aerated flows with smoothed particle hydrodynamics
Modelling aerated flows is a complex application of computational fluid dynamics (CFD) since the interfaces between air and water change rapidly. In this work, the simulation of aerated flows with the smoothed particle hydrodynamics (SPH) method is investigated with a focus towards the application in engineering practice. To prove the accuracy of the method, the processes of air entrainment and ...

Intensification of flotation treatment by exposure to vibration
In this paper, an intensification of wastewater flotation treatment by exposure to vibration is studied. Exposure to vibration results in the decrease of air bubble size, increase of air flow through the aerator and more even dispersion of air bubbles in water. This intensifies the aeration process, thus significantly improving the treatment efficiency. A multistage model of flotation kinetics ...

Optimizing Aeration Rate in Wastewater Treatment
OVERVIEW A significant portion of a wastewater treatment plant’s energy costs are due to aeration operations (~45-75% of the total energy). The required aeration rate of a biological treatment system is determined by three key parameters: incoming organic loading expressed in terms of COD or BOD, dissolved oxygen (DO) concentration maintained in the aeration tank, and the concentration of ...

Energy efficient aeration of wastewaters from the pulp and paper industry
More than 50% of the electrical power needed to treat pulp and paper industry effluents is used for aeration in biological treatment stages. A large share of the oxygen that passes through the wastewater is not consumed and will be found in the off-gas. Energy can be saved by aerating under conditions where the oxygen transfer is most efficient, for example at low concentrations of dissolved ...

Eliminating sludge islands in your wastewater lagoon
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. Of course, this is because the solids entering the lagoon have enough weight to fall out of the water as flow velocity is reduced, so the solids pile up just after ...

Development of a model for activated sludge aeration systems: linking air supply, distribution, and demand
During the design of a water resource recovery facility, it is becoming industry practice to use simulation software to assist with process design. Aeration is one of the key components of the activated sludge process, and is one of the most important aspects of modelling wastewater treatment systems. However, aeration systems are typically not modelled in detail in most wastewater treatment ...
