text_B: Rotating Cell Biofilm Reactor -LRB- RCBR -RRB- is a new type of biological process based on biofilm active sludge used in wastewaters treatment .. biofilm. biofilm. wastewaters treatment. Wastewater treatment. RCBR reactors represent an evolution of Rotating Biological Contactors plants  : in fact , they are able to develop about ten times the biological surface of Rotating Biological Contactors plants , considering the same biological reactors volume -LRB- made of the set of disks -RRB- .. Such a result is obtained using - instead of a set of disks fixed on the central structured tree - many tridimensional plastic elements as carriers .. These carriers are used to furnish the necessary biological surface for the cohesion of the bacterial film , responsible of the depuration process .. These plastic elements are contained in a cilindric permeable cell , which is like the shape of the reactor cell of a traditional rotating RBC plant .. One of the main peculiarity of the RCBR plant is represented by the fact that the biological carriers are common recycled water bottle plastic caps .. The intrinsic message of this technology is obvious  : `` transform a waste into a resource for the environment '' .. After a first settling and / or screening treatment , wastewaters to be treated -LRB- civil , industrial , domestic -RRB- are pumped into RCBR modules .. By the wastewaters contact , plastic caps are covered by a bacterial biological film .. Bacteria are nourished by the organic substance dissolved into the water , purifying it .. Purified waters can be drained on a surface body water or on the ground .. If they are conveniently disinfected and complementing the modules with a tertiary depuration plant , these waters can be used to irrigate , to full the toilets , to wash objects and streets .
