Tomorrow Water introduced the Proteus high-rate filtration system for wastewater treatment during WEFTEC in Chicago.

The system uses floating media and effectively removes suspended solids and soluble organic compounds through physical filtration and biological treatment. As a replacement for primary clarifiers, it can shrink process footprints while increasing carbon capture and biogas production.

The process can be applied for treatment of primary and wet-weather flows, secondary treatment without clarifiers, tertiary filters and nitrification/denitrification. It can be used for retrofits and plant expansions.

The expanded polypropylene media provides a high solids-loading rate with a unique shape and a high void ratio. Gravity-based zero-energy backwash uses only process water for cleaning. With continuous aeration capability and no settling required, the system can manage high peaking factors and variable flow rates, simplifying treatment of dilute flows. Visit www.tomorrowwater.com.
