SUBMERGED-TYPE FILTRATION APPARATUS

摘要

Disclosed is a submerged-type filtration apparatus which can be easily installed, safely and comfortably maintained, and enables observation of bubbles discharged from an aeration tube during filtration work. The submerged-type filtration apparatus of the present invention comprises a filtration bath having raw water needed to be processed input, and located on the ground; multiple filtration membrane modules arranged in line in the filtration bath; and an aeration tube arranged under the filtration membrane modules, and discharging bubbles toward the filtration membrane modules, wherein the filtration bath has a transparent window on a lower part for a discharge state of the bubbles to be observed from the outside of the filtration bath.
