The Algal Turf Scrubber® (ATS) can be designed and constructed to meet a wide range of nitrogen reduction goals. ATS™ units have been successfully applied to surface water, agricultural runoff, and domestic wastewater with total nitrogen concentrations ranging from 1-18 parts per million (ppm).

Chart-1Whether your treatment objective is nitrogen load reduction to meet TMDL requirements or to reduce wastewater discharge concentrations to below current Advanced Wastewater Treatment Standards (AWT), Algal Turf Scrubber® systems can be optimized to meet the most stringent water quality goals.

Designed to operate at hydraulic loading rates of 200-400 cm/day, Algal Turf Scrubber® systems can annually remove from 500 to over 8,000 pounds of nitrogen per process acres for a wide range of point and nonpoint source applications.

Annual nitrogen removal rates of over 6,400 pounds per acre of treatment area have been achieved while treating stormwater runoff in the Lake Okeechobee watershed. When compared to large constructed treatment wetlands operated under similar nitrogen inflow concentrations, the Algal Turf Scrubber® was able to remove over 200 times more nitrogen per acre of treatment area.
