Filter medium, process for preparation thereof, filtering method and filtering apparatus

摘要: A filter medium comprising a body of the having space thereof partitioned three-dimensionally, irregularly and manifoldly by bent linear members strength sufficient to cause substantially no substantial deformation when is actually used, an effluent pipe connected medium, said opening located in interior body, from which filtrate flows out, disclosed. When at least one component filtered or separated material be treated dispersion as interposed between cake surface portion allowed pass very easily through cake. Accordingly, clogging not caused filtration can performed uniform flow rate throughout operation. In addition, process for preparation such filtering method apparatus using are provided. This effectively used any field separating components dispersions, example, oils water.
