Abstract
A filtration apparatus includes a flow path, a valve provided on the flow path, a first light source configured to emit a first light including ultraviolet (UV) light toward the flow path, a second light source configured to emit a second light including visible light or infrared light toward the flow path, a first optical sensor located out of a path of the first light and the second light, electrodes provided on the flow path, and a processor electrically coupled to the valve, the first light source, the second light source, the first optical sensor, and the electrodes. The processor is configured to alternately operate the first light source and the second light source, receive a first signal from the first optical sensor while the first light source emits the first light, and control the valve and the electrodes to sterilize the flow path based on the first signal.
