Welcome to the Floating Island powerpoint presentation Welcome to the Floating Island powerpoint presentation! These notes have been written to expand on the slides and help you to present the main points to others, or to enjoy it at your own computer screen. If you have any questions or any suggestions for improvement, we’d love to hear from you (please contact Anne).

Floating Treatment Wetlands are the newest advance in the established field of constructed wetlands. The BioHaven® Floating Treatment Wetland is the “most innovative” constructed wetland technology developed to date. New Zealand Institute of Water and Atmospheric Research

He turns for inspiration to the natural floating peat bogs of the Chippewa Flowage, Wisconsin, which he knew from his youth, and days as a fishing guide. Associated with clean water and with world-record muskies, he studies them and looks to nature for inspiration.

Nature BioHaven Matrix The base of the natural floating island consists of a matrix of roots; our search for a man-made equivalent took us to our matrix (Americo is the manufacturer), made of 100% recycled polyester, filtration material, certified non-toxic, coated with acrylic, UV-resistant (being tested at present).

This is meant as a quick overview. Move on This is meant as a quick overview. Move on. The time to explain the fabrication in detail – and to show an island – is on the slide “how BioHavens work”.

Effluent water polishing The largest launch to date (June 2008 launch). Positioned near the outlet of the fish-hatchery, to “polish” the effluent water before it enters the Bow river. The water has been circulated and recycled 11 times before it gets to this point, then fed through a constructed wetland, consisting of a shallow pool and gravel. The biohaven “floating fen” gives it a concentrated boost of microbial activity. This is not a pilot study – no measurements being taken.

Unaffected by fluctuations in water levels Versatility - simple, passive to active, dynamic Zero-to-low power consumption Solar, wind Small footprint Deep water applications Intensified results Modular – add more as needed Additional values - habitat, aesthetic, economic Aggressive aeration capability Temperature homogenization De-stratification ability Don’t plug up – see “pathways” coming up for an explanation. The matrix is sufficiently open to allow good circulation (this was tested in the R&C study). Intensified results = concentrated wetland effect.

Important points: Slide one: BioHavens provide surface area for microbes. Concentrated surface area Microbes remove contaminants from water, such as the ones listed on the left (carbon, phosphorus, heavy metals (eg, copper and zinc), nitrates, ammonium. These microbial processes are well documented. Microbes “consume” nutrients which would otherwise produce algae. The more biofilm (microbes) the less algae. Biofilm forms, containing millions of microbes bonded together, reproducing like crazy (populations double within 2 – 3 hrs and sometimes 20 mins). They can’t reproduce without a surface area because they are single-cell organisms that reproduce by splitting in two. Microbes secrete sticky stuff which other stuff bonds to: algae, suspended solids in the water. This is without plants! Click: adding plants adds a whole new dimension. The roots provide even more surface area for microbes, especially when you take into account the roots hairs. The plants themselves take up nutrients, but only 15 – 20% of the total. Microbes do 80 – 85% of the work.

The Sequestration Pathways

The Sequestration Pathways - upward Carbon is sequestered in terrestrial plant growth on top of the islands

The Sequestration Pathways - upward Here you see gas coming off biofilm in a Leviathan runway

The Sequestration Pathways - downward Carbon is sequestered in organic debris accumulating below the islands

The Sequestration Pathways - inward Carbon is sequestered in roots and microbes growing within the islands

The Sequestration Pathways – outward – Floating Supermarket effect Carbon is sequestered in the organisms that benefit from the islands

MBRCT Grant #1 Nutrient Removal - matrix only Reduce Nitrate at a rate of 10,600 mg/(ft2*day) Reduce Phosphate at a rate of 428 mg/(ft2*day) Nitrify ammonia at a rate of 770 mg/(ft2*day)

This is the data from the NIWA study, relating to storm water. They used 4 native NZ wetland plants, pre-vegetated with good root growth. These results are excellent and show great promise for biohavens in storm water ponds. See NIWA article on our website for full description of the research

“The aeration system is a coiled tube that forms a disk and air is pumped into the tubes.  The small bubbles emitted from the disks aerate the lake and cause an upward draft to mix the lake.  This helped but still was not enough.  This spring they installed six 250 foot Floating Islands and it is believed that the combination of aeration, mixing and habitat for zooplankton is what has made a huge difference for managing the algal blooms”.
