Enhanced Primary Treatment Reduces Energy By Separating BOD Before Aeration

At WEFTEC 2016, Evoqua Water Technologies explored six core challenges faced by wastewater treatment plants -- energy reduction, nutrient removal, odor and corrosion control, aging plant equipment, water reuse and disinfection. In this Water Online Radio interview, Paul Rice, Municipal Marketing Director with Evoqua Water Technologies, discusses energy reduction and nutrient removal in more detail.

As Rice explains, enhanced primary treatment is an energy reduction strategy that is gaining momentum where BOD is separated out before aeration and sent to digestion, resulting in more biogas and less aeration energy.  

For nutrient removal, Rice discusses Evoqua’s Orbal System which utilizes a concentric loop design to achieve simultaneous nitrification denitrification and also touches on a redesigned aeration disc called Ox.
