Uniform Aeration. Optimized Performance.

Supporting a Modern WWTP Process
The City of McMinnville undertook a comprehensive modernization of its Water Reclamation Facility to increase biosolids processing capacity and improve long-term operational efficiency.
The project included:
-
A new Autothermal Thermophilic Aerobic Digestion (ATAD) process
-
Expanded biosolids storage
-
Modernized instrumentation and controls
-
Replacement of the existing odor control facility
-
These improvement provide the City with additional solids treatment capacity while supporting reliable, long-term odor control for the upgraded process.
The Challenge

The implementation of a new ATAD solids treatment process introduced new odor control requirements.
The upgraded facility required a biological odor control system capable of reliably treating the increased odor loading associated with the new solids treatment process while providing a long-term solution for future plant operation and possible expansion. The city would need something beyond the capabilities of the existing pipe-and-gravel system.
The BacTee Solution
The BioAer® Aeration Floor System was selected to provide uniform airflow distribution beneath the biofilter media while eliminating many of the operational limitations associated with conventional pipe-and-gravel systems.
The modular removable floor provides:
-
Uniform air distribution across the entire media bed
-
Simplified maintenance and access
-
Reduced potential for airflow channeling
-
A durable support system designed for long-term municipal operation
By constructing a new BioAer® equipped biofilter, the City was able to integrate the upgraded solids treatment process while maintaining operational flexibility throughout the transition, with the intent to phase out the old pipe-and-gravel system.
