The Next Generation in Floating Wetlands

In 2005, when BioHaven Floating Islands came to the attention of eminent wetland scientist Dr. Chris Tanner, he heralded them as the “new generation” of floating treatment wetlands. Tanner immediately began a research program to measure their ability to remove nutrients and heavy metals from stormwater. His success sparked over a decade of BioHaven research at leading universities and institutes around the world.

What Makes BioHavens Different?

  • Their matrix structure is a perfect plant-growing platform, allowing perennial plants to fully mature and be effective over many years without reaching a performance plateau.
  • They are a quasi-hydroponic system that uses a growing medium to supply plants with nutrition that does not leach into the water.
  • Oxygen is allowed to permeate the upper layers to benefit plant growth, while below the waterline, biofilm covers every fiber.
  • The permeable matrix, even when coated in biofilm, does not plug up.
  • Plants, plant roots and BioHaven matrix combine to perform a vast surface area for biofilms to attach to as the optimal pathway for removal.
  • Their internal buoyancy provides depth and rigidity, making them extremely robust.
  • They are scalable in length, width and depth to meet the demands for small and large system sizing, suitable for use in any waterbody.

Our Expertise

Floating Island International has partnered with biofilm engineers and plant scientists to bring a best-in-class approach to nutrient management and water resource recovery. Our engineers are graduates and associates of Montana State University’s world-class Center for Biofilm Engineering and fully understand the water remediation and recovery environment. Our plant specialists are experts in choosing hyper-accumulator plants and microbes for the best possible phytoremediation results in aquatic settings.

Case Studies

To verify the efficacy of our products and to enable comprehensive sizing of new projects, FII and partners conduct extensive field testing. Project results are published in FII case studies. Our case studies are unique to BioHaven technology and do not correlate with any other floating wetland system.
