Floating Islands

The engineered BioHaven® Floating Treatment Wetlands (FTW) bio-mimic natural wetlands. The FTW remove harmful nutrients such as nitrates, ammonia, BOD, phosphorus, suspended solids and other pollutants in urban, rural and industrial water bodies. The FTWs provide an exponentially higher surface area for plants and microbes to thrive in than those found in naturally occurring or constructed wetlands. Therefore, they are also called Floating Concentrated Wetland (FCW) because they actually stimulate and expedite the natural process.

Organic solids stick to the biofilm and become the base of the freshwater food web, for fish and other aquatic life. BioHaven floating treatment islands fluctuate with water levels without becoming stranded or inundated and are resistant to ice build-up. Above the waterline the BioHaven matrix supports dense plant growth and nurtures a healthy riparian and wildlife habitat.

There are about 40 different known applications for the floating islands which can be summarized in the following categories: water quality improvement in ponds and lakes, waste water treatment, habitat restoration, shore erosion control and protection, aquaculture, landscape beautification, bio-dock, streambed...
