Beautify and add interest to the waterscape
Thick with green growth and with the colorful spark of flowers a small floating Island will be an enchanting addition to any waterscape. Islands can be small enough for a water garden or large enough to help clean larger water ponds. There are no hard and fast rules of what size island to add; go with the number of islands that looks best! Attaching several islands together can look stunning in a backyard pond!

BioHaven™ Floating Islands
The unique matrix material of the island, a unique blend of re-cycled polyester fibres, actually allows plants to grow as if they were in rich soil. The roots of the plants absord nutrients directly from the pond, reducing the phosphates and other nutrients in the pond while flourishing plants bloom on the floating island and provide shelter and nesting areas for birds, turtles and other pond creatures.

The islands are available in standard shapes and sizes ranging from 25 square foot up to 400 square feet.
Custom sized island sizes and shapes are available and include the required amount of planting BioMix

Canals and ponds in cities and towns can become a haven for birds and aquatic creatures. This panoramic photo shows 19 floating islands clustered along a river that slowly winds through the City of Chicago. Such projects can bring residents together as they take ownership of their environment.

Natural improvement of water quality. Report on the East Lake Floating Island Project

Floating Islands can be an effective tool in maintaining the health of water gardens, ponds and lakes. The island itself is constructed of a patented combination of materials that encourage the stabilization and efficient growth of plants and vegetation.

The plant root structures that grow through the floating island's substrate feed on nutrients in the pond. Since these nutrients often lead to algae, cloudy water or mucky buildup a floating island becomes a natural water filter, one that is not only natural and highly effective, but also extremely beautiful.

By adding a floating island and a combination of aeration and beneficial bacteria to the same pond or lake you can see dramatic improvements in pond water quality. Islands are ideal for municipalities or in commercial applications where harsh chemicals are not an option but a water treatment program is required.

BioHaven^™ Floating Islands are on the cutting edge of water quality maintenance and habitat restoration and are available through CanadianPond.ca Products Limited. The floating islands use the basic principles of hydroponics to clean ponds and lakes via the filtration effects that plants offer. BioHaven floating islands are available in sizes ranging from 25 to 400 square feet and beyond.

Root structures penetrate the materials of the floating island and absorb surplus nutrients from the pond or ecosystem providing a natural cleansing of the pond. BioHaven^™ Floating Islands use patented materials and designs, making them the only choice for any serious project involving water treatment or guaranteed aesthetics and longevity.

Islands can be easily attached together to create larger areas or clustered groups.

Beautify and add interest to the waterscape
Thick with green growth and with the colorful spark of flowers a Floating Island will be an enchanting addition to any waterscape. Islands can be small enough for a water garden or large enough to help clean larger water bodies. The pond cleaning powers of the island are increased with aeration systems and bio-augmentation.

Wastewater and Stormwater Management Easy to manage 4 foot by 8 foot floating island modules can be attached to form extremely efficient filtration systems to reduce suspended materials, reduce phosphates and nitrates, and help sequester carbon. This diagram shows possible ways of retrofitting a given surface area of floating treatment wetland into the wet pond stormwater treatment system recommended in ARC TP10.

Enhance fish habitat
Fish will naturally benefit from improvements in water quality, and the root masses growing down into the pond water help provide a source of food source for small fish - which in turn feed the bigger ones. Fish regularly gather under floating islands to take advantage of the cool shade and to escape predators like herons, osprey, and eagles.

<< This photo shows a large floating island being anchored in place. The choice of plants and vegetation is dependent on the local conditions and the wishes of the client.

Indigenous plants are often best but some islands use a combination of decorative flowering aquatic plants with hearty grasses. An island this size can be planted and anchored into place in a few hours by 3 or 4 people.

Provide wildlife habitat
Floating islands provide resting and nesting habitat for ducks and loons, avocets and snipe, and a host of other local bird species. Frogs deposit their eggs on the plant root structure, salamanders patrol the waterline, turtles climb aboard out to sun themselves, and dashing blue dragonflies hover and feed on mosquitoes..

Floating islands overcome many of the disadvantages and limitations of current biotechnology for natural water purification. By providing an expandable biological process to include wetland plants perched in artificial substrate, add-on super airlift biofilters, add-on subsurface aeration and a regimen of microbial supplements, the technology efficiently and effectively breaks down aquatic pollutants in lake, pond, wetlands and wastewater environments.

Built of recycled polymer matrix bonded with marine foam, the BioHaven^™ Wild Floating Island creates a super-enhanced floating habitat. Water can circulate through the body of the island and plant roots can grow through it. Compared to earthen islands, the BioHaven Wild Floating Islands are lighter, easier and less expensive to install, allow plants to establish faster, and can extend the growing season.

Scientific Construction

• Plant growth substrate is recycled polymer matrix. Plant roots can easily grow through, and anchor to, the excellent plant base.
• Matrix fibers and wetland plant root hair provide high, specific surface area attachment points for colonization of nitrogen- and phosphorus-reducing microbes.
• Substrate also supports microbe attachment and growth of select beneficial microbes. On-site biofiltration and rapid nutrient removal is possible. The aerobic microbial purification process converts waste organic matter in two steps: by direct oxidation of biodegradable matter, and by endogenous respiration where cellular material is oxidized. The entire process is carried out by specialized, naturally occurring microbes developed over years of research. These processes can be illustrated in the following two equations:
  • Eq 1: Organic matter + NH₄⁺ + Cellular Material + nitrifying microbes +C0₂ + H₂0
  • Eq 2: Cellular material (nutrients) + Oxygen ^microbes digested sludge + C0₂ + H₂0 + N0₃
