When selecting an HDS device you might just be checking for 80% TSS removal rates and moving on. But what does that mean? Sure the device says it was tested, but on the red clay of Tennessee or the sands of Florida?
All too often MTD selection does not take into account the nature of the particles present in the runoff. Depending on soil types your next project may need to consider that an HDS should not be expected to perform well in a clay or silt-dominated environment. For best results in those cases, a filtration device is needed. On the other hand, an HDS is a good option for coarser materials such as sand and loam.
Check out this free selection tool to pick the right option for your next design.
Easy to use selection tool helps engineers identify hydrodynamic separation (HDS) and filtration options based on soil types.
