Indirect Potable Reuse Pilot Test
Innovative Aquifer Recharge
Our pilot test developed a treatment train that produced high quality effluent while reducing costs.
Project Outcomes and Benefits
- Developed a treatment approach that minimized the need for reverse osmosis treatment that is typically used for indirect potable reuse, potentially greatly reducing capital and operating costs.
- Demonstrated acceptable emerging contaminant oxidation using treatment technologies alternative to MF/RO/UV-AOP that are more cost effective and have a smaller carbon footprint.
- Produced water that satisfied primary and secondary drinking water standards with the exception of certain constituents present in the Floridan Aquifer, such as chloride.
- Included the following process components in two flow streams - diverted secondary effluent from the wastewater treatment plant clarifier, chlorine addition, deep bed media filtration, ultrafiltration, ion exchange (TOC, Ammonia, Phosphate), ozone, UV-AOP, and BAC filters.
- Monitored several emerging contaminants that may be regulated in the future.
- Pilot test found that both process schemes are viable options for recharge in Broward County and to the state reuse requirement.
