Wastewater Lagoon Treatment

BioHaven Floating Islands can extend the life of a rural community’s wastewater lagoons, buying the citizens time while they plan for the inevitable upgrade. Large treatment facilities can utilize BioHavens to polish their tertiary effluent. Retrofitting existing assets with BioHavens is straightforward, non disruptive and scalable. They can be added incrementally as budget allows.

With BioHaven Floating Island lagoon treatment you can expect:

  • Proven technology verified by independent case studies

  • Year-round biological removal of key contaminants

  • Active and passive systems or a combination of both

  • Non-disruptive installation, nominal maintenance and low operator input

  • Specialized plants that target specific pollutants

How BioHavens Help Wastewater Lagoons

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.

The main function of floating islands in removing pollutants from effluents is:

  • Growth of plants, and biofilms on matrix and root surface, uptakes phosphorus. 
  • Aerobic and anaerobic bacteria, which co-exist within the biofilms, promote nitrification / denitrification and BOD removal. 
  • Plant roots assist in filtering and settling TSS.
  • Mild acidification of water due to release of humic acids, and a C input from senescent vegetation; assisting denitrification.
  • Ammonia removal requires aeration for nitrification and anoxic conditions for denitrification. Both processes occur simultaneously in BioHaven treatment under aerobic conditions.
  • Cold-weather ammonia removal, which is a temperature-dependent process, has been effective with BioHaven systems (Rehberg Ranch, Billings, MT).

BioHavens can easily be adapted to suit a wide range of situations. They can:

  • Fit into any existing lagoon or polishing pond
  • Work within the energy limitations of the facility
  • Operate in cold climate or extreme environmental conditions
  • Be adjusted to manipulate specific treatment conditions
  • Be installed in stages to meet changing treatment requirements

We work directly with the client or with city engineers to design a tailored solution:

    • Utilizing a proprietary BioHaven-specific modeling tool, system sizing is optimized
    • Our engineers understand the resource recovery environment and remediation technologies
    • Installation and service contracts available.
