  • Oriented structure for treating a fluid
    Patent number: 6602407
    Abstract: An oriented structure for treating a fluid, comprising an inlet end for receiving a fluid to be treated and an outlet end opposite the inlet end and from which a treated fluid is discharged, the fluid being allowed to flow into the structure from the inlet end to the outlet end defining a flowing direction. The oriented structure comprises a juxtaposition of layers of porous material having a different porosity, each layer spanning from the inlet end to the outlet end of the structure whereby in use the layers are oriented generally parallel to the flowing direction of the fluid. The oriented structure is designed so to better control the different biological and physical phenomena related to the accumulation or exchange processes taking place in the structure.
