Algal Turf Scrubber® systems are supported by a 30 year performance record in research and commercial applications.

Since the late 1970s, researchers from around the U.S. have developed the use of Algal Turf Scrubber® systems for recovery of excess nitrogen and phosphorus from domestic and agricultural wastewater, and more recently stormwater. These studies repeatedly showed that Algal Turf Scrubber® systems were capable of effectively recovering nutrient pollutants for a broad range of water quality conditions.

Today, with advanced design and biomass recovery methods, the Algal Turf Scrubber® has the ability to cost-effectively remove nutrient pollutants from impaired surface waters and provide a valuable tool to meet TMDL requirements.

Decades of research and operation are incorporated into each Algal Turf Scrubber® facility design.  From system enhancement using patented phosphorus precipitation methods, to patented biomass management techniques, no other periphyton-based technology offers comparable performance and experience. Our Mobile Pilot Units ensure system design is calibrated to on-site conditions, and the company holds exclusive license rights allowing the use of harvested periphytic algae as a livestock feed ingredient.
