BioHaven Floating Islands mimic natural wetlands in form and function. Using sophisticated man-made materials, BioHavens are easy to handle and easy to install. Different product models are also available to fit specific purposes: private pond aesthetics, lagoon-scale municipal wastewater treatment, high-energy breakwaters and coastal restoration.

  • labelGeneral Description

    All BioHavens share the same unique characteristic: the high volume of bio-reactive surface area provided by the high-tech matrix. Upon launching, the matrix delivers instant benefits and continues to deliver habitat and water quality improvements throughout its long life. Its longevity is assured by the protective armor coating it receives during the manufacturing process.

    BioHaven matrix is robust, tolerant of wind and waves in high-energy settings. It is inert and long-lasting as well as lightweight and flexible. BioHaven technology is a sustainable, green infrastructure solution that provides benefit to any waterbody.

    For large projects, such as water resource recovery and wastewater projects, BioHavens can be scaled up to whatever size our proprietary modeling program determines is required.

    BioHaven solutions can be configured passively, actively or in combination. Projects can take advantage of natural circulation through the biofilm-covered surface area utilizing BioHaven Floating Islands. Projects requiring active airlift technology to aerate or to force water to circulate more aggressively through the matrix can utilize one of our StreamBed systems.

    BioHavens are a superb platform for allowing the bushy-rooting perennial plants that grow through the matrix to fully mature and form an extensive root biomass below the island. The upper layers of matrix lie above water level, ensuring the oxygen transfer necessary for plants to thrive; once their roots descend into water, they pull their nutrients from below.

    A huge range of wetland and non-wetland plant species thrive in our matrix, including specialized hyper-accumulator plants. The BioHaven platform has been chosen by NASA plant scientists to deliver their patented technologies for water remediation and nutrient recovery projects.

    BFIs come in two standard sizes, large and small. They can be either rectangular with rounded edges or have naturalized shaping. Each BFI has two fixtures for anchoring or tethering to shore. Optionally, BFIs can be joined together in a cluster for larger projects requiring greater nutrient removal or aesthetics.

    BFIs have sufficient buoyancy to support a profusion of healthy plants but not the weight of an adult. They are suitable for low-wind, low-wave environments. Size and buoyancy can be customized.

    BioHaven Streambed (BSB) / Forced-Flow StreamBed FFSB)

    BSBs integrate an efficient, low-energy airlift system into the BioHaven matrix. There are two standard models:

    • The BSB has a stream channel on top that allows deep water to be drawn up into it and exposed to the atmosphere. Its main purpose is aeration.
    • The Forced-Flow BSB sits mostly below the waterline to promote optimal biofilm growth. The stream channel is submerged, allowing water to circulate through the matrix under pressure. The FFSB has heat-retention capabilities for increased wintertime efficacy. Its main purpose is forced circulation particularly in a wastewater environment.

    Both BSBs can be anchored or tethered. The blower assembly in both systems is housed onshore.


    WasteWater BioHaven (WWB)

    WWBs are passive BioHaven modules specifically designed to be scaled up for treatment applications. They are joined together with corrosion-proof fittings and tethered to shore. Easy access for maintenance is designed in through a central walkway.


    High-Energy BioHavens (HEB-W, HEB-N)

    HEBs are substantial BioHaven modules engineered for settings that experience high winds or waves. HEBs have multiple anchor points for extra security in tough conditions.

    Vegetated EcoShield™ uses BioHaven matrix technology to protect stream banks and the leading edge of coastal systems from erosion. It is available exclusively from our partner Martin EcoSystems.

  • labelEnvironmental Safety Statement

    BioHaven Floating Islands are made of inert, long-lasting materials that are fit-for-purpose and certified safe for use in the environment. FII avoids the use of organic materials that readily break down and contribute to aquatic oxygen depletion.

    The BioHaven matrix is manufactured with 100% recycled PET-sourced from plastic drinking bottles. These are mandated by the FDA to use the highest quality fiber available. Its high intrinsic viscosity (IV) ensures the quality of recycled matrix fiber exceeds most virgin fibers and keeps millions of bottles out of landfills each year. It is important to note that PET sinks and is not found in the floating garbage gyres in the ocean.

    Every BioHaven receives a polyurea coating of ‘armor’ that maintains its integrity against UV damage and against the pecking of ducks and geese. The armor is the same material that is used to line municipal concrete water tanks and truck beds and meets food-grade quality standards.

    BioHavens are lightweight when dry and can be handled safely without the use of heavy equipment. If they have to be removed from their waterbody for any reason, drying them out on shore first will facilitate transportation.

    Today, there are legitimate concerns about microplastics in water which are too small for normal filters to remove. Specifically, these are beads used in exfoliants and such. BioHavens are actually one of the few technologies that can remove them because they stick to biofilm-covered surfaces.

    After 15 years of rigorous testing, no side effects have occurred utilizing BioHaven technology. When we consider the multitude of noxious and harmful pollutants known to be in water, BioHaven’s proven ability benefits the overall environment.
