Constructed wetlands are commonly used to cleanse water of pollutants. They work by exposing water to natural processes - microbial processes - facilitated by plants and organic matter. In order to expose as much water as possible to the beneficial activity of the wetland, they are created wide and shallow.
This approach is natural and effective, but very costly in terms of the land required to create this shallow, wide tract.
 BioHavens act like a constructed wetland but with none of the land requirements. They represent a concentrated wetland effect. With the huge surface area presented by the individual matrix fibers, every 250 sq ft island equates to 1 acre of wetland surface.
Whenever you launch a BioHaven you effectively launch a floating wetland. The water doesn't have to be shallow for the benefits to be realised - solar-powered pumps can be used to circulate water through the island to increase exposure to microbial activity.
Floating Treatment Wetlands (FTWs) are a relatively new development. In a recent review of all the offerings on the market today, NIWA (the National Institute of Water and Atmospheric research, of New Zealand) identified BioHaven floating islands as the most innovative and advanced of all.
