Jaeger Aeration, the Pioneer of Fine-Bubble, first provided the direct 9” disc membrane as a direct replacement for ceramic diffusers. Evolution of membrane extrusion and testing provided the 1 and 2-meter Tube diffusers, which are more SOTE% efficient.
Ultimately, we introduced the OxyStrip product, which increases the membrane area per diffuser and increases the SOTE% even higher than the OxyTube diffuser.
Our innovations make the connections fewer while increasing the performance of membrane technology. Giving our clients more process options and higher energy efficiency for a lower O&M cost.
To the right are the SOTE% transfer curves and the differences between the products. The smaller the bubble, the higher the efficiency due to surface area.
A few of the technical differences are as follows:
Low Headloss across membrane
High SOTE% as the bubbles “spread out”
Multiple membrane materials
Cyclic Air capabilities without risk of plugging
Reduced connections
Consolidation of aeration to reduce construction costs
Oxygen transfer is a matter of bubble size and surface area. Jaeger Aeration has proven that over the past 50 years in business.
The smaller the bubble size, the larger the surface area.
The larger the bubble size, the lower the SOTE%.
The finer the bubble size, the higher the SOTE%.
The graph to the right illustrates that efficiency comparison. All mechanical devices (rotors, disc aerators, turbine aerators, aspirating aerators, jet aeration, and floating aerators only produce about 3#/Hr/Hp for oxygen transfer.
Fine bubble diffusers are more than 5#/Hr/Hp, which is a huge saving as illustrated in the graph to the bottom right from Farmington MO for direct power savings.
Jaeger Aeration's OxyLift OxyStrip product line was selected to replace a mechanical aeration product. To prove the energy savings graph above from Farmington MO, Jaeger Aeration installed the OxyStrip project to provide redundancy and higher efficiency (Lower O&M costs). The savings for the 2mgd facility are illustrated in the graph to the right. The net difference is over 50,000 kWh/month, which relates to wholesale electric savings as follows:
Savings: $6,000/Month or 21 Metric Tons of CO2/Month or 24000 pounds of Coal/Month
