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
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
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.
