Loading-type multi-stage filtration device |
| abstract |
[Problem] To provide a loading-type multi-stage filtration device capable of improving, with high efficiency, water quality to the level of beverage applications by ensuring sufficient contact time with filtration sand in a space-saving manner. [Solution] A loading-type multi-stage filtration device 100 comprises: a first filtration tank 20 into which rainwater stored in a rainwater tank 10 enters; a second filtration tank 30 that is connected to the lower part of the first filtration tank such that the first filtration tank is stacked thereon; a fresh-water tank 70 that stores purified rainwater filtered by at least the first and second filtration tanks; and a control water tank 80 that receives rainwater from the rainwater tank and that is connected to the fresh-water tank to enable adjustment of the storage capacities of the rainwater tank and the fresh-water tank. |
