Lagunair technology

Treatment of olfactory nuisances from lagoons and storage of process water.

Lagun’Air technology has been designed for the treatment of bad odors generated by pools, lagoons or malodorous pools of water, of all sizes and shapes, stagnation or in motion .

Some examples of treatments with Lagunair:

  • sewage treatment plants
  • lagoons
  • reservoirs
  • storage tanks for process water

The Lagun’Air process is applicable to all types of ponds or lagoons, whatever their size.

Lagun’Air products are formulated to treat water of all kinds.

We use this system in many areas of activity:


  • sugar factory
  • canning
  • petrochemistry
  • distillery
  • dehydration of vegetables
  • waste treatment
  • water purification
  • and many others

How does Lagunair work?

Lagun’Air can be diffused on or under the surface of the water.

The active ingredients will slowly evaporate and come into contact with the smelly molecules, as soon as the molecules appear above water, ensuring olfactory neutralization.

Lagun’Air products are stored and delivered through an automatic feeding unit designed and developed by Biothys™.

The operation of this unit is fully programmable.

The setting of the time slots and the diffusion sequences of the product makes it possible to optimize the consumption of the treating product.

Lagoon of leachates treated by a Lagun’Air unit with 12 injection nozzles and a wind vane.

Advantages of LAGUNAIR technology

The Lagun’Air process is managed by a simple programming of the injection sequences.

The position of the injection network allows precise control of the residential areas to be protected.

Can be managed by a wind vane to treat only when the winds are unfavorable compared to the sensitive area to protect.

Possibility of manual implementation by simple gravity or by means of a pressure sprayer or thermal backpack atomizer.
