LEVIATHAN™
Treatment Wetland

Floating Island International offers a variety of products incorporating patented BioHaven® technology, none more powerful than the Leviathan.

Leviathan uses integrates high-volume, low-head circulation with matrix surface area for maximum wetland performance. Its efficient air-driven directional diffuser draws in and aerates in excess of ten thousand gallons of water per minute, pushing it through the BioHaven matrix and plant roots. A key innovation is the floating streambed, which contributes to the aeration and nutrient uptake.

In a standard Leviathan configuration, nutrients and contaminants are exposed to over 1,000,000 square feet of sticky, biofilm-laden surface area; however, Leviathan is scalable. In fact, those now being designed are large enough to circulate up to 10,000 gallons of water every minute. This makes Leviathan floating treatment wetlands the most promising biological tool for lake restoration and cleaning up the damage caused by oil spills and other man-made and natural disasters.

Leviathan floating treatment wetlands can be complemented with conventional BioHaven floating islands, optimizing the opportunity to provide a landscaped habitat for fish and wildlife while cleaning polluted water.
