Application of dissolved oxygen (DO) level control for polyhydroxyalkanoate (PHA) accumulation with concurrent nitrification in surplus municipal activated sludge.

This study suggests a method for PHA accumulation using nitrifying activated sludge, while feeding ammonia-containing organic feedstocks by means of DO level control where: (1) NOB activity and growth are both mitigated, (2) nitrogen removal is facilitated, (3) alkalinity is controlled through simultaneous denitrification, and (4) energy demand for aeration is reduced.
