Description: Advancement of Ozone-BAC Treatment Processes for Potable Reuse Applications
Advancement of Ozone-BAC Treatment Processes for Potable Reuse Applications
Abstract
Two advanced water treatment techniques (Ozone-Biological Activated Carbon and Reverse Osmosis) were compared to establish a baseline relationship between their effluent TOC levels and for the potential formation of disinfection byproducts. Six full scale ozone-BAC plants across US were sampled and their effluent data compared with two full scale RO systems. A pilot scale operation of an Ozone BAC system was also performed to optimize the operational parameters to achieve maximum removal of organic material. Further, microbial characterization of the media samples from the full and pilot scale operation will be conducted by sequencing the V3-V4 hypervariable region of the 16S rRNA gene. Ozone BAC proved to be a promising technique in terms of treatment efficiency and biological activity.
