Indian River County’s Egret Marsh Stormwater Park Opens Featuring HydroMentia’s Algal Turf Scrubber®

December 1, 2009

Vero Beach, Florida (December 2009) – Indian River County’s Public Works Stormwater Division has officially opened the Egret Marsh Stormwater Park. The park features the Algal Turf Scrubber® water treatment system designed by HydroMentia, Inc.

HydroMentia’s Algal Turf Scrubber® technology uses algae to remove excess nitrogen and phosphorus from water. Polluted water is conveyed to the Algal Turf Scrubber®, where it is pulsed in waves across a sloped floway. Algal turf or dense mats of simple algae are cultivated on the surface. As the algae grow, they remove nutrient pollutants (nitrogen and phosphorus) from the water. Algal bio- mass is then regularly harvested and processed into an organic soil amendment. Excess nutrients are thus safely and beneficially recycled.

The Egret Marsh Regional Stormwater Facility will treat fertilizer-laden urban and agricultural runoff currently discharging to the Indian River Lagoon. By reducing nitrogen and phosphorus levels, the ATS™ will allow the county to better meet Total Maximum Daily Load (TMDL) limits for these nutri- ents and reduce harmful algal blooms while improving overall water quality. These improvements are one part of Indian River County’s comprehensive program to restore the Indian River Lagoon – the most biologically diverse estuary in North America.
