BioHaven technology is successfully used to protect and restore sensitive coastlines
Protection and restoration of sensitive coastal areas is a key use of BioHaven systems. The proven wave-dampening qualities of the BioHaven Matrix allows it to function as a breakwater, absorbing energy and protecting the shoreline from further damage. Its ability to act as a sediment trap enables marsh grasses to be re-established and thrive in areas where they have disappeared. The projects covered by this case study have been hugely successful, and have garnered a Gulf Guardian award for Shell Oil, a key proponent of this technology.

Marton Waste Water Treatment (New Zealand)
First-of-its-kind floating island “Lid” eliminates odor, reduces BOD and cuts annual operating costs. In this innovative application of a BioHaven floating island from New Zealand, a blanket or lid is built to cover and treat a pond anaerobically, thereby reducing troublesome odors which had until then plagued the residents of Marton. This treatment option was highly successful in improving the effluent, and saved the city approximately $150,000 in annual operating costs. Please Choose Case Studies from the Form Below |

Prototype BioHaven FTW Streambed treats private sewage lagoon
Lodi, California A BioHaven Streambed FTW installed in a wastewater retention pond reduced levels of ammonia, total nitrogen, BOD and TSS by up to 99%, 78%, 96% and 95%, respectively. The visual appearance and odor of the pond were noticeably improved after BioHaven installation. Please Choose Case Studies from the Form Below |

BioHavens north of Chicago win storm water BMP award for local conservation group
Barrington, IL The Citizens for Conservation used BioHaven floating islands to augment a wetland for storm water treatment in a housing sub-division in Barrington, IL. Their algae problem disappeared and dissolved oxygen levels went up – and Sandhill cranes successfully reared chicks on the islands. Please Choose Case Studies from the Form Below |

Elevated BioSwales: using floating island technology to treat runoff in streams and ditches
Shepherd, MT and Virginia BioHaven matrix has been successfully deployed in the treatment of runoff inside streams and ditches prior to it entering a lake or river. By form-fitting the swale to the stream channel, circulation is assured, short-circuiting is eliminated and treatment capacity is optimized. Please Choose Case Studies from the Form Below |

Floating Island Provides Bass Spawning Habitat
Elephant Butte, New Mexico USA The New Mexico Bass Fishing Association’s mission is to enhance bass fishing habitat and opportunities within the state. A subgroup of the association, Kids of the Southwest, undertook a project in 2009 to increase the bass population at Elephant Butte, NM. These youth partnered with the New Mexico Game and Fish Department, marina owners and other local interested parties after discovering a Floating Island International licensee, Floating Islands West, which has developed floating botanical gardens to increase fish and other wildlife habitat, along with providing water quality improvements.

Floating island habitat gives endangered bird (California Clapper Rail) hope for survival
Arrowhead Marsh, Oakland, California This is the story of how the clapper rail, a nearly-extinct species of bird threatened by rising sea levels and loss of coastal marshland, has been given a new hope by deploying floating islands to biomimic its natural habitat.

Establishing Brush Park Aquaculture - combining BioHaven technology with wisdom from SE Asia
Minnow Pond, Shepherd Research Center Native minnows are an established and widespread solution for keeping disease-bearing insects under control. Brush-park aquaculture has been practiced for centuries in SE Asia where the yield per acre is phenomenal. This case study documents how we have created ideal conditions at the Shepherd Research Center to support a burgeoning population of fathead and stickleback minnow, following the brush-park principles.

Floating Islands Remove Propylene Glycol from Airport Stormwater in an independent study
Bangor, ME, USA This case study demonstrates the capabilities of Floating Island International’s (FII) patented floating treatment wetland (FTW) technology and its ability to purify water by significantly reducing carbon concentrations. Constructed of post-consumer polymer fibers and vegetated with native plants, FTWs mimic the ability of natural wetlands to clean water by bringing a “concentrated wetland effect” to any water body – in this case, an aerated stormwater pond.

Early-stage study shows removal of BPA (estrogen mimicker) by Floating Treatment Wetlands
Test Tanks, Billings, Montana USA This elegant study, conducted by two senior high school students as a prize-winning entry in a Science Fair competition (under the supervision of Dr Mark Osterlund), used Betta fish to measure the impact of doses of Bisphenol-A. This is a chemical pervasive in our waterways which causes fish to become sterile. When the test fish were subject to the chemical, their gill flares declined rapidly, indicating a loss of virility. However, when floating islands were present, the fish recovered quickly and were back to normal within 10 days. This study suggests that more research would be well justified, and very timely.

A BioHaven® Floating Island is tested in a harsh Marine Environment off the coast of SE Alaska
Elfin Cove, SE Alaska Two modules were launched at Elfin Cove, AK, to study the affect of salt water on plants, to find out what biota would colonize the islands and see how the islands would hold up to the forces of Nature in a marine environment. After a whole winter in the water, the island maintained its buoyancy and structure, and the perennial plants came back in the spring. Please Choose Case Studies from the Form Below |

Early-Stage Floating Island Achieves Nutrient Removal in Aerated Facultative Wastewater Treatment Lagoons
Wiconisco Township, Pennsylvania, USA Results of this case study illustrate the early stages of the FTW technology as passive installations with no integrated circulation or aeration. They represent the first steps in the progression of the FTW technology in wastewater treatment applications. As with any technology, early versions serve as the critical basis for refining and developing more advanced latest generation manifestations. Please Choose Case Studies from the Form Below |

Enhancing fish productivity in the Chicago River: a Masters Capstone project
In this study by a Masters student, fish numbers were measured at three nearby sites: in open water, under a dock and under a BioHaven floating island. The BioHaven showed statistically higher numbers of fish than the other two sites. Please Choose Case Studies from the Form Below |
