Report
Summary
Aeration membrane diffusers facilitate oxygen transfer during the aeration process at the wastewater treatment plants located at 23rd Avenue and at 91st Avenue. Testing services document the performance of existing aeration membrane diffusers. These tests are used by treatment plant staff to make aeration membrane diffuser replacement decisions and to minimize energy usage during the aeration process. Regular aeration membrane diffuser testing confirms that the correct amounts of dissolved oxygen are transferred during the aeration process to ensure permitting compliance.
