a wise investment

KAMAK technology is based on floating biological reactors specifically designed according to actual treatment needs. It is the perfect solution for phasing capacity increase projects. Investment is thus gradual, as urban development progresses.

Developed in Canada and its design ensures treatment performances for the harshest northern conditions. Materials used provide a high resistance level to waves, winds and ice.

Biofilm growth on its patented media provide for optimal performance in cold waters, for carbonaceous degradation as well as nitrification.

The technology relies on its ease of operation and energy efficiency.



Floating biological reactors

  • Modular according to lagoon geometry
  • HDPE structure (weather resistant)
  • Permanent diffusers = no replacement needed
  • Contain BIONEST media

patented media

  • High treatment capacity: increases purifying bacteria concentration
  • Fixed: no risk of media loss into the environment
  • Permanent: no degradation over time
  • Freestanding: no fluidization energy required
  • Reliable: treatment resistant to hydraulic and toxic shocks
