SAFL Baffle Comparison SAFL Baffle vs Hydro Dynamic Separators Attribute SAFL Baffle Hydro Dynamic Flow Performance (CFS): 80 Cubic Feet per Second 8 Cubic Feet per Second TSS Removal Efficiency: 84% 85% Maintenance: No Maintenance Requires Routine Maintenance Longevity: Guaranteed 20 Years No Guarantee Materials: All Stainless Steel (No Plastic) Plastic Ease of Cleanout: Easy Complicated By-Pass Required? NO YES Cost: $5,000 $24,000 The Minnesota DOT switched from Hydro-Dynamic Separators to the SAFL Baffle and in 3 Years, saved the taxpayers over $8 Million Dollars! The SAFL Baffle: Provides lowest cost per pound sediment removal High Performance: 80 CFS Long Life - Guaranteed 20 years Typical comparison found on over 1000 projects SAFL Baffle Hydro Dynamic Separators Cost: $5,200 TSS Removal Efficiency: 84% By-Pass Flow Rate: 80 CFS Cost: $24,00 TSS Removal Efficiency: 85% By-Pass Flow Rate: 8 CFS Operates by stopping the vortex The SAFL Baffle stops the natural vortex that is created in standard sump structures, dissipating hydro energy and causing sediment to drop to the bottom of the sump. As sediment collects in the bottom, the SAFL Baffle's design prevents vortex scouring and resuspension, retaining all previously captured sediment, even during high-flow storm events up to 80 cubic feet per second. Operates by creating a vortex Hydro Dynamic Separators operate with average flows of 8 cubic feet per second. At greater flows, stormwater bypasses the device and does not capture any sediment. Internal plastic parts are prone to vibrate and break. SAFL Baffles can, and have been, retrofitted in existing hydrodynamic structure for a cost-effective replacement.
