Multiple stage treatments

Every emission has its own history, its own impact and its own treatment technology.

Physical and chemical characteristics, type of emission process, emission location, neighbouring context and ways of managing the treatment, are some aspects making each single emission problem special and unique. 


Odors treatment, due to the complexity, vastness and touchiness of its various aspects, implies some rules as regards design. Quite often, it is not possible to consider only one single operation, i.e. one treatment only. 

This is why Labiotest designs “special” plants, i.e. hybrid plants, as custom-made systems resulting from Multiple stage treatmentsa thorough knowledge of various treatment methods. Redesigned in view of a group action, they ensure exceptional abatement rates, while keeping management costs and by-products to the lowest possible level

This last aspect is often more strategic than the choice of the abatement system itself.  


Special plants

Among various hybrid systems it is possible to design wet + dray solutions, based on the washing action of a liquid solvent and selective adsorption of substances having no affinities with the solvent. 

The result is a high abatement rate in a wide range of applications. Costs remain under control due to the optimization of reagents or adsorbing materials used in high yield processes only. 

Otherwise, solutions may foresee the introduction of advantages by means of a stack osmogenic barrier. This allows for an additional olfactometric reduction, when system performances tend to decrease (or in the case of revamping), due to scarce maintenance or reduced adsorbing power. 

To increase the olfactometric power, it is thus possible to include natural substances capable of linkinghydrophobic substances in the watery phase and neutralize them from an olfactometric point of view in the aerial phase, during the evaporation process. The result is an olfactometric abatement rate of 50% and more, if compared to that of a simple wet system, and there is no production of by-products or additional waste.  

The ability consists in creating a multiplestep process by making the best possibleuse of each intermediate process in orderto optimize the efficiency of followingabatement steps.
