Wastewater Lagoon Treatment
& Water Resource Recovery
Treating wastewater lagoons with BioHaven Floating Islands can mean huge savings for the small community struggling to meet discharge standards.BioHaven lagoon treatment can extend the life of lagoons and buy the community time until an expensive upgrade is called for. Large treatment facilities can utilize BioHavens to polish their tertiary effluent and even achieve Water Resource Recovery (WRR) through harvesting marketable products, such as forage fish or trees. Retrofitting existing assets with BioHavens is straightforward, non-disruptive and scalable.
How a BioHaven Floating Island Works in Wastewater Lagoon Treatment
BioHavens promote a type of fixed-film treatment that employs bio-reactive processes in combination with plant remediation. The floating island matrix provides an effective treatment surface as water is circulated through the fine mesh to promote biofilm growth. As plant roots grow unimpeded through the permeable matrix, a massive surface area is created within and beneath the island to accommodate the bacteria that consume organic matter and nutrients in wastewater. Suspended solids are digested (organic) or sloughed off (inorganic). The symbiosis between plants and microbes increases both microbial activity and plant growth to provide an unsurpassed, natural, inexpensive water-cleaning approach.

Marton, New Zealand
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. |
