Full Description

This study evaluated the potential of ozone-assisted biofiltration (OAB) for removing taste and odor(T higher MIB removals were observed in filters with higher EBCTs.Most of the MIB removal occurred in the top few inches of the filters indicatingpredominance of biological oxidation in the upper layers of the media. Increasing ozonedose resulted in slightly enhanced MIB removal. The GAC/sand filters outperformedanthracite/sand filters in terms of total organic carbon (TOC) and UV254 reductions. Higher heterotrophic plate counts (HPCs) wereobserved in GAC/sand filters compared to anthracite/sand filters indicating higherbioactivity in GAC/sand filters. Both GAC/sand and anthracite/sand filters producedwater with turbidities less than 0.2 NTU. Includes 5 references, figures.
