Abstract
A method of producing an algal turf for use as a scrubber of carbon dioxide, nutrients and pollutants as well as biomass production is disclosed. A growing surface for spores or benthic microalgae is provided on a water surface. The growing surface is subjected to periodic water surge action to promote metabolite cellular-ambient water exchange and light is provided, natural or artificial to promote growth. The growing turf is harvested before being overgrown by larger macroalgae.
