MegaBubble installed at MMSD Oak Creek facility

MegaBubble mixers were installed in July of 2015, they have been running since with only scheduled maintenance and contiunue to run.  Though MegaBubble mixers use air, ORP levels for biological phosphorus removal are below -150 and mixing is consistent through the whole water column.  

MegaBubble in action

12 MegaBubbles installed in the anaerobic basin for biological phosphorus removal.  On the bottom, one will notice the fine bubble aeration, while on the top of the animation one can see MegaBubble mixers deploying intermittently.  The mixing is adequate to keep solids in suspension while using a small fraction of the energy needed for convention aeration, while also keeping dissolved oxygen to a minimum.
