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. **In cooperation with TPO magazine (Treatment Plant Operators Magazine)** [Register here](https://register.gotowebinar.com/register/7435386228523364621?utm_source=newsletter&utm_medium=email&utm_content=Veolia%20Webinar%20Banner&utm_campaign=TPO211018)
