Reduced Land Requirements

Algal Turf Scrubber® systems are optimized to create flow conditions that maximize the nutrient uptake of the algal turf. Optimal hydraulic loading rates for Algal Turf Scrubber® systems are typically 40-100 times higher than constructed wetland systems. Higher hydraulic loading results in greater biomass production and higher pollutant removal rates, thus less land is needed.

HydroMentia End ProductsIn typical stormwater applications, Algal Turf Scrubber® systems will remove 200-1,000 pounds of phosphorus and 500-8,000 pounds of nitrogen for every acre of process area. At these rates, Algal Turf Scrubber® systems require only 3-5% of the land area of comparable treatment wetlands.

The footprint for a 10 mgd treatment module requires as little as 2.5 acres, making the Algal Turf Scrubber® ideal where land is limited.
