Batch-type apparatus for filtering

A batch-type filtering apparatus, comprising:

• a filter cartridge;
• a first flow path configured to guide filtrate received from the filter cartridge;
• a second flow path configured to communicate with the first flow path;
• a third flow path configured to communicate with the first flow path;
• a fourth flow path configured to communicate with each of the second flow path and the third flow path;
• an external port configured to communicate with each of the third flow path and the fourth flow path;
• a first direction switching valve configured to allow at least two from among the first flow path, the second flow path, and the third flow path to communicate with each other;
• a second direction switching valve configured to allow at least two from among the third flow path, the fourth flow path, and the external port to communicate with each other;
• a flow cell connected to the third flow path, and configured to store therein the filtrate that has passed through the first flow path and the first direction switching valve while the first flow path and the third flow path are in communication via the first direction switching valve;
• and
• a vessel connected to the second flow path, and configured to store therein the filtrate discharged from the second flow path.
