Abstract
(EN)
A water treatment device comprising: a jet nozzle (7) for mixed raw water flow; a filtration tank (5) for containing a filtration material layer (4) which comprises two layers which are an upper layer (2) and a lower layer (3) and are arranged below the jet nozzle for mixed raw water flow, the upper layer consisting of filtration materials having a smaller specific gravity and a greater particle diameter than the filtration materials of the lower layer; a water collecting/distributing pipe (13) for extracting filtered water and supplying reverse washing water to the filtration material layer in reverse washing operation; a filtration material vibrating means for vibrating each particle of the filtration materials, the filtration material vibrating means being provided with a vibration element (9) connected to the power source and also with vibration expansion elements (10) embedded in the upper layer (2) in such a manner that the vibration of the vibration element (9) is transmitted to the vibration expansion elements (10); and a drainage trough (12) provided above the filtration material layer.
