Low oxygen start‐up of partial nitrification‐anammox process: mechanical or gas agitation?

BACKGROUND Partial nitrification‐anammox (PN‐A) is a widely recognized technology to remove nitrogen from different types of wastewater. Low oxygen concentration is the most used strategy for PN‐A start‐up, but stability problems arise during the operation; thus, in the present study the effects of...
