Coarse Bubble Diffusers
Coarse bubble diffusers are suitable for almost any type of water and wastewater application. The primary application of coarse bubble diffuser systems today are as indicated below: Aerobic Digestion Applications Coarse bubble diffusers have been the traditional diffusers used in these applications. The standard design rate for this application is 30 scfm per 1000 ft of tank volume. ...

An assessment of oxygen transfer efficiency in a gas permeable hollow fibre membrane biological reactor
The clean water oxygen transfer efficiency (OTE) of a full scale non-porous hollow fibre gas permeable (GP) membrane (surface area of 500 m2) was evaluated at inlet air pressures of 1.2, 1.4, and 1.8 atm using two established testing methods. To form a basis of comparison with traditional aeration technologies, additional testing was done with conventional aerators (fine bubble and coarse bubble ...

Surface Aeration or Diffused Aeration
When designing lagoon aeration systems selection of optimum aeration components is critical to maximum performance, long-term operation and easy maintenance. Lagoon aeration is generally broken down into two major categories surface aeration and diffused aeration. Surface Aeration Lagoon aeration systems dating back to 1960’s were almost all surface aerators. Surface aerators are still ...

Submerged Fixed Film: Top 5 Considerations for Evaluating Different Systems
Submerged fixed-film systems are ideal for significantly increasing nitrification in existing wastewater treatment plants. A well-designed and operated system can double the nitrification capacity of an existing aeration basin. When choosing media for fixed-film applications, typical options include small, floating biomass carriers (moving bed systems) or structured-sheet PVC modules fixed in ...

Maximum Air Pressure for Diffusers
In the water and wastewater treatment field there are many needs and/or opportunities to upgrade existing facilities or to construct new facilities where space is limited. The available space can severely constrict the capacity of treatment facilities, or reduce the options available for design and implementation of the treatment process. Some of the needs facing many potential facilities is the ...

Field Performance of Fine and Ultra Fine Bubble Diffusers
History - Coarse, Medium, Fine Bubble Diffusers Diffuser efficiencies are generally measured in clean water to allow basis of comparison of similar products and prediction of actual performance in a wastewater treatment plant application. Before standard testing procedures were implemented, SOTE data were managed by the various suppliers of aeration equipment with optimistic results from ...

Fine Bubble Aeration
Fine bubble aeration systems are inherently more efficient in oxygen transfer than coarse bubble aeration systems. Overall, a fine bubble aeration system configured in a grid configuration will operate at approximately 50% the energy consumption of coarse bubble systems. Because of this high operating efficiency and corresponding reduction in energy consumption, fine bubble aeration systems have ...

Modelling a full scale membrane bioreactor using Activated Sludge Model No.1: challenges and solutions
A full-scale membrane bioreactor (1,600 m3 d−1) was monitored for modelling purposes during the summer of 2006. A complete calibration of the ASM1 model is presented, in which the key points were the wastewater characterisation, the oxygen transfer and the biomass kinetics. Total BOD tests were not able to correctly estimate the biodegradable fraction of the wastewater. Therefore the wastewater ...

The rehabilitation of 43 year old waste lagoons
In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. The main industry in Concordia is a Tyson renderings plant, and the lagoon system was designed to also handle that plant’s final waste and water polishing requirements. The lagoon system was a relatively standard design, consisting of an 18.7 acre primary lagoon, a 5.6 acre ...
