■ 回転板によってゆるやかな水流が生じ、その水流に
のって破砕されたスカムは、スリットから消化室に容易
に移行する。■ A gentle water flow is generated by the rotating plate, and the crushed scum is easily transferred from the slit to the digestion chamber.
■ ゆるやかな水流があるために仕切ホッパー面にスカ
ムが堆積するおそれがない。■ There is no risk of scum accumulating on the partition hopper surface because of the gentle water flow.
■ スカムが発生した場合でも隔壁があるのでスカムが
越流堰に移行することはない。■ Even if scum occurs, the bulkhead prevents the scum from moving into the overflow weir.
■ 万一浮遊物の一部が隔壁の発孔を通過したとしても
隔壁内の静止水面内で沈降し、下部の仕切ホッパーから
消化室へ移行するので流出することはない。■ Even if some of the floating material were to pass through the holes in the bulkhead, it would settle within the still water surface within the bulkhead and move from the lower partition hopper to the digestion chamber, so it would not flow out.
