摘要
A stormwater treatment system having a treatment container with two chambers, a treatment chamber and a bypass chamber. The bypass chamber includes an inlet for receiving stormwater. Disposed adjacent the inlet is an overflow tray secured to the walls of the bypass chamber. The tray includes an inlet opening for receiving the stormwater to be treated, and a discharge opening through the baffle wall that separates the two chambers for discharging stormwater that enters at low flow rates. The stormwater to be treated passes through the discharge opening into the treatment chamber where it is treated by the filter media. High flow rates will bypass the treatment chamber by overflowing a dam wall or weir defined by the overflow tray directly into the bypass chamber. Treated water from the treatment chamber passes through an underdrain pipe that enters into the bypass chamber. All water from the bypass chamber exits through pipe openings, preferably on each of three sides of the bypass chamber wall.
