Large Energy Savings for Equalization (EQ) Basins - Case Study
AP Series Air-Powered Wastewater Mixers provide better mixing with less CFM.
Topics: energy savings, eq basins, mixing
Basin Overview:
West Basin: 30,000 square feet. For raw sewage influent.
East Basin: 20,000 square feet. For a mix of secondary effluent and raw sewage influent.
Operating depths for both basins ~4 - 6 feet.
Pre-Deployment Conditions: Both basins contained grids of coarse bubble “tube style” diffusers for mixing. They were powered by three (3) 75HP blowers, one dedicated for each basin, and a third for use as a spare.
Project Objectives: To provide thorough mixing and solids suspension with less CFM as well as to eliminate the need for a high-horsepower mechanical mixing system.
Solution: A total of forty (40) AP2000 Air-Powered Wastewater Mixers and two (2) 25HP blowers.
- West Basin: Twenty-five (25) AP2000 mixers.
- East Basin: Fifteen (15) AP2000 mixers.
Results: Improved mixing requiring substantially less CFM. The Customer observed significant energy savings estimated to be upwards of 135HP.
Update (February 2019): The Customer continues to be very happy the AP2000 mixing system.
