Hydro DryScreen® Next Generation Baffle Box

The Hydro DryScreen® is a next generation baffle box designed to effectively remove a wide range of solids from stormwater runoff. It augments the typical baffle box design, wherein vertical baffles are used to create a series of sediment settling chambers, with a patented flow-diffusing mechanism to improve sediment capture.

The chamber contains both horizontal and vertical screens to capture larger materials such as trash and leaf litter. The horizontal screen sits above the standing water level in the sump, preventing captured gross organic solids from leaching dissolved nutrients between storm events.
