Two filter medium layers are, therefore, formed both at the top and the bottom of the chamber 1a. The original water is divided into upward and downward flows, which are filtered by layers of the floating filter medium 6 and the sinking filter medium 7 respectively. When a rate of filtration becomes slow, a pump P is stopped, the original water is made to flow reversely and discharged through the supply port 8 and a discharge pipe 12 until a water level arrives at a lower limit L of a water level gauge 15. Next, a washing air is ejected into the original water by a blower B, the floating filter medium 6 and the sinking filter medium 7 are agitated for the sake of having suspended substances, which are attached to them, removed, and the original water containing those substances is discharged out the discharge pipe 12. The washing of filter media is finished and the filtration process is reopened, after the original water is once again supplied into the filtration chamber 1a, the aeration washing is repeated for a short time and the original water containing remaining suspended substances is discharged.
