Devices, apparatus, systems and methods of using baffle boxes with turbulence deflectors and flow spreaders. Turbulence deflectors are added about the inlet port of a baffle box, and a flow spreader is added centrally beneath an outlet port to increase removal efficiency of pollutants and prevent the conveyance of pollutants down stream. The turbulence deflectors and the flow spreader will increase the removal efficiency of particles, especially fine and ultra fine particles without impeding the water flow. The turbulence deflectors will significantly reduce the turbulence within the sediment chambers which will lead to better settling and less re-suspension. The flow spreader spreads the flow wide sooner within the baffle box to reduce the linear velocity of the water current, and directs water flow away from the area of greatest turbulence adjacent to the inflow, and will increase the settling of particles and minimize re-suspension. By increasing the removal efficiency of the first sediment chamber the shielding will prevent the re-suspension of fine and ultra fine particles.
