Stormwater Suspended Solids Reduction in Sand-Zelbrite Filter Media

Abstract:

The use of the filtration process based on zeolite for stormwater treating has been recently increased. This study reports the results obtained from a laboratory experimental testing on a treatment unit consisting of a gravel drainage layer, a filtering media composed of zelbrite (a synthetic zeolite) and silica sand. The filter media is fed with typical stormwater particulate matter (PM) loadings. The treatment performance is evaluated in terms of total suspended solids (TSS) reduction. In addition, the transformation of PM particle size distribution (PSD) through the filtering media is also determined. The findings show that TSS reduction varies from 76% to 91% for different influent PM loads.
