BioHaven floating islands can treat
organic carbon and suspended solids better than traditional methods
- and for a fraction of the cost.
Conventional technology can get the job done, but only at a very
high cost. Estimates, generated by consultants, are that Montana
municipalities would have to spend between $800,000,000.00 to one
billion dollars to achieve compliance over the next seven to ten
years, relying on existing technology.
However, floating islands are a viable, cost-effective
alternative. As our islands prove successful and achieve pollution
uptake numbers in the field, we are confident we will be able to
reduce these costs by 75%!
FLOATING ISLANDS FOR WASTEWATER AND STORMWATER
* Superior performance to constructed wetlands
* A viable solution to pollution
* Very affordable
A "Concentrated wetland effect"
BioHaven floating treatment wetlands (FTWs) cleanse water of the
major pollutants commonly found in groundwater. They remove
nitrates, ammonia and phosphates at a level comparable to
engineered solutions, but unlike other systems, they do so at the
same time. They are also effective at removal of heavy metals, such
as zinc and copper, when present in the water column as suspended
Their removal of suspended solids and BOD is extremely
Typically, after wastewater has passed through treatment
facilities, there is still a high level of Phosphate present, which
is finding its way into our major waterways and contributing to
pollution and even dead zones in the ocean. In the new regulatory
environment, levels of Phosphate must be drastically reduced.
Constructed wetlands have proven themselves to be an effective,
natural way of removing pollutants, but they have some
disadvantages. More recently, Floating Treatment Wetlands have come
on the scene, improving performance and reducing the drawbacks.
Research shows that, of these, by far the most successful are
BioHavens, out-performing the next best by 2000%. They have
additional advantages: they take up no land; they keep pace with
water level fluctuations; and they work in both shallow and deep
BioHaven floating islands act as floating treatment wetlands, only
more so. They provide a concentrated wetland effect.
BioHaven FTWs are constructed from a non-woven matrix made of
recycled plastic, and injected with foam for initial buoyancy.
Thousands of square inches of tiny matrix fibers (left) provide an
expanded surface area for microbes to colonize - aerobic microbes
which consume phosphates and ammonia, and anaerobic microbes which
convert nitrates to harmless atmospheric gas. Once the BioHaven is
launched, biofilm begins to grow inside and around it (biofilm =
microbes). As water circulates through and across the island, the
biofilm gets to work on the pollutants. The more the surface area,
the more biofilm forms, and the more nutrients are removed.
Inexpensive solar- and wind-driven pumps can assist water
re-circulation. A limited amount of aeration is necessary to
support phosphate removal.
Stormwater ponds experience similar problems with pollutants, and
are often challenged by heavy metals such as zinc and copper, which
are too fine to be filtered mechanically. Suspended particles
attach to the biofilm and the roots of plants growing through the
matrix. Eventually they slough off and fall to the sediment where
they remain sequestered as long as anaerobic conditions are
BioHavens are eminently suitable for both wastewater and
stormwater "polishing". Floating islands deployed in a wastewater
treatment setting should be resilient to fluctuations in water
quality influent. Some research even suggests they may help to
lower operating costs because of the optimal way they utilize
With BioHaven FTWs, though, you get more than a water polisher -
you steward your waterway with a beautiful natural system and
provide habitat for a myriad life forms in the process. BioHavens
can be made to any shape or any size, can be "off the shelf" or
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.
