Abstract

This study is conducting comparisons between effluent quality of full-scale ozone-biologically activated carbon (BAC) and reverse osmosis (RO) systems by measuring various organic/inorganic water quality parameters. Assessment of relationship with levels of disinfection byproducts (DBPs) and/or their respective precursors will be performed. Pilot testing will allow for ozone dose optimization and performance evaluation of columns operating at two different empty bed contact times. Measurement of various water quality parameters (including total organic carbon) and their relationship with DBPs will be examined. Media microbial characteristics will also be examined using 16S rRNA gene amplicon sequencing.
