Waste-gas treatment and odour removal

In Likusta waste-gas treatment systems, harmful and odorous substances from waste-gas and exhaust-gas flows are decomposed to non-toxic, odourless and largely low molecular weight substances. This is done biochemically by the metabolic activity of microorganisms.

Your system from a single source

At Likusta, we believe that plant projects should be planned and implemented as a whole, not as a combination of isolated packages. This is why we create our own electrical design and manufacturing.
