F:M Treatment in an Activated Sludge Plant

Wastewater systems located in regions with high annual precipitation, such as the Pacific Northwest, are prone to experiencing biological washouts due to high infiltration and inflow (I&I) from collection systems. I&I can critically disrupt the biological treatment at a plant.

Increased storm water and infiltration inputs can dilute influent organic substrate and washout established biomass. As a result, the biology in the system losses connectivity with the food supply and functional community structure. The following reference of work describes the application of ProBiotic Scrubber® II (PBII) and Candy Carbon® (CC) to restore the biological treatment in an activated sludge plant (ASP).
