This paper presents study conducted on air driven rotating biological contactor. The wastewater treatment efficiency was examined in two different discs submergence. The results of studies indicated that the treatment efficiency with 70% discs submergence was 84.75% while with 100% discs submergence wastewater treatment efficiency was 84.38%.

In this paper presented preliminary results of studies conducted on a laboratory model of rotating biological contactor driven by compressed air. As a result of tests it was found that the average COD removal efficiency using hybrid technology was 85%, while using only the biofilm this value was 33%. The calculated contribution of the biofilm in the wastewater treatment by a hybrid process was approximately 50%.
