OBIT technology is a biological deodorisation technology developed and aimed at treating odours in wastewater treatment plants. It offers environmental and economic benefits over chemical deodorisation.

The OBIT technology operation is identical to chemical scrubbers, and the treatment is performed by bacterial cultures immobilised in a specialised support to achieve high treatment performance. The main attributes of this technology are the ability to co-treat several pollutants in one reactor, and the fact that no chemical reagent addition is required, making this technology more sustainable than chemical scrubbing. Since the OBIT biological treatment occurs in identical operating conditions as chemical scrubbing, the conversion of existing chemical scrubbers into OBIT treatment systems is feasible with minor infrastructure adaptations, providing significant environmental and economic advantages.
