The concept of sequential biofiltration combines two infiltration steps with an intermediate aeration to established favored oxic and carbon-limited conditions for enhanced biotransformation of trace organic chemicals in the second system. This study provides first results from combination of sequential biofiltration with intermediate ozonation and GAC post-treatment for water reuse.

University of Nevada, Reno (UNR) Nevada Water Innovation Institute is conducting a comprehensive pilot testing under OneWater Nevada initiative investigating the emerging frontiers in potable reuse Ozone-Biofiltration treatment systems: 1) inactivation of Crypto and Giardia, 2) bromate formation during potable reuse ozonation, and 3) determination of biofilter empty bed contact time (EBCT).
Evaluating Direct Potable Reuse using Ozone Biological Filtration without Reverse Osmosis

Gwinnett County, Georgia currently practices potable reuse through surface water augmentation. The feasibility of direct potable reuse (DPR) to achieve potable quality water without the use of reverse osmosis (RO) was evaluated through a 10-month pilot study. An alternative treatment train with ozone-biological filtration was used to treat various blend ratios of reclaimed water.
