Floating treatment media, or floating treatment wetlands, provide a vast surface area within the plant root zone. Within this root zone, pollutant digesting microbes and bacteria, bio remediate wastewater that is laden with nutrients, heavy metals and suspended solids.

Urbanization, waste treatment, landscape changes, agriculture, and natural resource extraction cause runoff of nutrients, contaminants, petroleum products, and organic materials to freshwater lakes around the world. The natural ability of plants and microbes to absorb nutrients (such as phosphorus and nitrogen) and break down contaminants through biological processes is known as bioremediation

Floating Treatment Wetlands (FTWs) or Islands are small artificial platforms that allow these aquatic emergent plants to grow in water that is typically too deep for them. Their roots spread through the Floating Islands and down into the water creating dense columns of roots with lots of surface area.
