Document Type and Number:
WIPO Patent Application WO/2016/084555
Kind Code:
A1
Abstract:
In the present invention, raw water flows from the lower side to the upper side in a raw water supply path (21) and goes over an overflow part (28) between the raw water supply path (21) and a separation tank (22), with the raw water flowing into the separation tank (22). A plurality of dams (41) forming flow rate differential control parts are provided on the raw water supply path (21) side of the overflow part (28). The plurality of dams (41) are provided in an arrangement in the direction of the rotational axis of a magnetic drum (24) on the separation tank (22) side of the raw water supply path (21). The upper end position of each dam (41) can be adjusted in the vertical direction by a prescribed adjustment mechanism.
