KLa Slot Injector™ Aeration System Expands the Capacity of an SBR at a Landfill Leachate Treatment Facility
The Challenge A landfill had an existing single basin SBR plant to process the leachate which is notable for its high nitrogen load. The original system was installed with a fine pore diffuser aeration system and due to the chemical/biological composition of the mixed liquor it was prone to diffuser fouling and premature membrane failure Over time this was detrimental to the biological process ...

The Power of the Duckbill
Backflow is among the most common causes of failure in bubble diffusion systems. Learn how adding only a few inches of elastomer can eliminate backflow risks and optimize diffused aeration processes. For a steadily growing percentage of wastewater treatment facilities, bubble diffusion systems are the centerpiece of an efficient, reliable, and thorough aeration process. In settings ranging from ...

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 ...

Floating Horizontal Aerators Enhance Eufaula, Alabama Activated Sludge Plant
The Eufaula, Alabama, wastewater treatment plant (WWTP) is an extended aeration activated sludge facility designed for an average daily flow rate of 2.7 million gallons per day (mgd). Prior to February, 2005 this WWTP used vertical aerators to provide oxygen and mixing in its aerator basins. The plant has two aeration basins, each 1.87 million gallons in volume, which had 160 horsepower (hp) of ...

Assessment of diffuser pressure loss on WWTPs in Baden-Württemberg
Aeration of activated sludge is a critical treatment step for the operation of activated sludge plants. To achieve a cost effective treatment process, assessing and benchmarking of aeration system performance are important measures. A simple means of gauging the relative condition of a fine bubble diffused aeration system is to evaluate the pressure loss of the diffusers as oxygen transfer tests ...

Indianapolis, Indiana Installations - Case Study
Maintain solids in suspension to prevent build-up in grit removal system for a dry weather flow of 70 MGD. SPECIAL REQUIREMENTS: The pulsed air mixing system is provided in JS101 B to suspend solids which settle out following grit removal so they can pass on downstream for further removal or treatment. Keeping solidsfrom accumulating in JS101B will minimize or eliminate the need to periodically ...

Full scale evaluation of diffuser ageing with clean water oxygen transfer tests
Aeration is a crucial part of the biological wastewater treatment in activated sludge systems and the main energy user of WWTPs. Approximately 50 to 60% of the total energy consumption of a WWTP can be attributed to the aeration system. The performance of the aeration system, and in the case of fine bubble diffused aeration the diffuser performance, has a significant impact on the overall plant ...

Energy Consumption Perfomance of Aeration Systems
One of the key factors to consider when evaluating performance characteristics of various aeration mixing system options is the predicted cost of energy to operate the system over its useful life. The challenge in calculating such costs is including efficiency data from manufacturers that reliably reflects performance one could expect to measure in the field. The performance of any aeration ...
