### Time: 13h00 - EST

**Webinar presented in English**

The **City of Portsmouth** in southeastern New Hampshire **upgraded** its 11 MGD Peirce Island WWTF with **a Veolia nitrification and denitrification BIOSTYR® system** to remove BOD and Total Nitrogen. By incorporating the BIOSTYR**®** system, the plant was able **to upgrade within its very limited footprint** and **meet strict EPA mandates** for TN discharge into the Piscataqua River, while maintaining the aesthetics of the economically and environmentally sensitive surroundings. In this presentation, the City of Portsmouth will share their experiences in technology selection (piloting efforts), construction, startup, and current performance of the plant and BIOSTYR**®** system.

**Hosted by WEF buyers guide**
