ABSTRACT:
A conical floway culture system for cleansing water of pollutants is presented that has a downward slope between the central region and the outer edge and a wall for retaining water within the floway. The water-impervious bottom surface has a texture conducive for growing an algal turf. In use, water is admitted into the floway from the waterway and is permitted to flow over the algal turf. The algal turf bioassimilates the pollutants and thereby cleanses the water, and the water is discharged in a cleansed condition. Mature algal turf is harvested periodically by an angled plowing system having a notched, fixed, or rotating scraper that travels in a downward spiral path, pushing harvested algal turf downslope toward the outer edge.
