Abstract
The present disclosure relates to a filter apparatus for oil-water separation, and according to an embodiment of the present disclosure, when the filter apparatus for oil-water separation is mounted in a mixed fluid storage tank for storing a mixed fluid collected in seas or rivers in the event that an oil spill accident occurs, it is possible to drain off only water in the mixed fluid. In addition, it is possible to increase the storage efficiency of the mixed fluid storage tank by selectively draining and removing only water other than oil and impurities in the mixed fluid stored in the mixed fluid storage tank.
Claims5
A filter apparatus for oil-water separation, comprising:
- a prefilter module having a hollow and half-capsule shape which has a semispherical end and an open end opposite to the semispherical end and allowing a prefiltered fluid in an external mixed fluid to flow in through an outer surface thereof while disallowing an external impurity in the external mixed fluid to flow in;
- and
- a first hydrophilic filter module having a half-capsule shape and abutting onto an inner surface of the prefilter module to filter the prefiltered fluid.
