The Osprey Marsh Algal Turf Scrubber® (ATS) facility is a full-scale surface-water treatment system located in Indian River County, Florida. The facility uses the Algal Turf Scrubber technology to support nutrient management, water quality improvement, and long-term operational evaluation under Florida field conditions.
Facility Summary
Facility: Osprey Marsh ATS
Location: Indian River County, Florida
Technology: Algal Turf Scrubber®
Scale: 10 MGD
Status: Operating
Initial Operation: 2015
Application: Surface-water treatment / nutrient management
Owner: Indian River County
HydroMentia Role: Technology provider, design support, and operational reference
Technology Description
The Algal Turf Scrubber® process uses shallow, sloped flowways that support attached algal communities. As water flows across the system, the algal turf assimilates nutrients and other constituents from the water. Periodic harvesting removes accumulated algal biomass from the system, providing a physical mechanism for long-term nutrient removal.
Operational Significance
Osprey Marsh ATS provides a full-scale operating reference for evaluating ATS design, operations, harvesting, solids handling, and long-term performance. The facility demonstrates the use of managed attached algal growth as a scalable approach for surface-water treatment and nutrient management.
