PURPOSE:To surely prevent carry-over even when high temp. raw water is flowed in, by providing an intake trough to the supernatant layer formed to the upper part of an inclined apparatus partitioned at every one pitch. CONSTITUTION:The supernatant layer 2 formed to the upper part of an inclined apparatus 1 is partitioned from the front part of a sedimentation basin 6 toward the rear part thereof by flow barrier plates 4 erected at every one pitch of inclined plates (pipes) 3 for constituting the inclined apparatus 1. A trough 5 is provided almost horizontal so as to pierce through each flow barrier plate for partitioning the above mentioned supernatant layer 2. Intake ports 7 for taking in water from the supernatant layer 2 partitioned at every one pitch are provided to the trough 5. As a result, because raw water exceeding the intake capacity of the trough 5 is surely prevented from rising through a water channel, carry-over can surely be prevented even when high temp. raw water is flowed in.
