Prevent nutrient pollution
Hydro DryScreen® stores leaves and organic material dry, rather than in a wet sump, preventing nutrients from leaching into stormwater.
Conventional screening baffle box designs send flow directly from inlet to outlet without slowing down the flow, causing debris to collect in piles and quickly blind some areas while not using other areas; in these boxes the velocity of direct flows are more likely to tear apart organic matter, causing it to fall into the wet sump and generate dissolved nitrogen and phosphorus.
Improve sedimentation performance
When the flow path is redirected by the patented flow diffuser it increases the time during which total suspended solids (TSS) remain in the Hydro DryScreen®, encouraging sedimentation of these suspended particles.
Reduce blinding and ensure optimal effectiveness
The flow diffuser distributes flow and debris evenly across the entire screen, reducing the risk of blinding and ensuring that the system continues to operate at its full design effectiveness.
The even flow distribution reduces the risk of ragging and blockage, and a larger screenings storage capacity than conventional baffle boxes means that the Hydro DryScreen® requires significantly less maintenance.
Adapt to a variety of site conditions
The Hydro DryScreen® works well with high peak flows, large pipes, shallow sites or anywhere where low headloss must be accommodated. The elevation can be adjusted to account for tail water or base flows.
