Reduce foam and bulking with pure oxygen
Using pure oxygen, lowers the formation of foams in biological treatments. The energy applied for stirring up is the minimum required for this purpose (unlike when air is use). Also, the lower biomass mortality due to the adequate oxygen transfer rate. Filamentous biomass caused by limited oxygen in the systems is also eliminated.
