Hydro DryScreen Performance Testing

Hydro DryScreen® performance testing.

This report reviews results from laboratory tests on a Type I Baffle Box, compares these results to estimates using settling equations in horizontal tanks and provides efficiency estimates for the Hydro DryScreen® Type II Baffle Box using Computerized Fluid Dynamics (CFD).  Full-scale laboratory testing was also completed to compare to both the CFD model and results of the original Type I Baffle Box laboratory tests. 

Removal efficiency testing correlated well with theoretical settling calculations for 80% removal of all particles down to 100 microns at about 30 gpm/sq-ft.  However, at high loading rates of 150 gpm/sq-ft 80% removals of particles down to 400 microns was measured compared to settling calculations that predicted removals down to the 700 micron range.
