The IFAS technology has increasingly been employed for incorporating BNR into large conventional activated sludge systems that are constrained by tankage or space availability. The incorporation of fixed film into activated sludge systems enables the resultant IFAS systems to significantly increase the total SRT of the system and achieve more or better treatment within a smaller existing or new footprint than CAS systems. The webinar will share the background, design details and challenges of two large IFAS BNR systems.
