HydroMentia Technologies LLC develops and supports natural, cost-effective, and sustainable water treatment technologies for nutrient reduction, water quality improvement, and aquatic ecosystem restoration. The company’s work is centered on the Algal Turf Scrubber® (ATS), an attached-algae treatment technology that uses managed algal growth and periodic biomass harvesting to remove nutrients from water.
HydroMentia’s experience includes commercial-scale managed aquatic plant systems, full-scale ATS facilities, pilot-scale demonstrations, and long-term operational evaluations across a wide range of treatment settings. These applications include stormwater and surface-water restoration, agricultural and municipal water treatment, industrial water management, and nutrient polishing for sensitive receiving waters.
The Algal Turf Scrubber® technology provides a practical treatment platform for converting excess nutrients into recoverable algal biomass. By combining ecological processes with engineered floways, controlled hydraulics, and routine harvesting, ATS systems provide a sustainable approach for improving water quality while supporting long-term nutrient removal.
