Abstract

A stormwater treatment device includes a tank defining an internal volume and having an inlet and an outlet, a rotatable screen unit mounted within the tank, the rotatable screen unit defining a through path with an inlet end and an outlet end. The rotatable screen unit includes a screen structure with a plurality of screening openings for allowing passage of at least some stormwater from the through path outwardly through the screen structure while inhibiting passage of at least some trash items through the screen structure such that the trash items move along the through path from the inlet end to the outlet end. The stormwater treatment device may include both a normal treatment flow path and one or more bypass treatment flow paths.
