Minimizing Mixing Energy in Activated Sludge Selector Basins. How Low Can You Go?

With the goal to minimize energy consumption in the BNR process, a mixing energy pilot study is under way at MMSD in Milwaukee, WI. Results show that power consumption of only 0.28 W/m3 is sufficient to fully homogenize activated sludge. This record-setting low energy mixing is achieved using a high-efficiency adjustable-thrust submersible… More
