Abstract
A bubble generation device capable of causing bubbles to hit filtration membranes almost simultaneously includes a housing having side plates and a top plate fixed to the side plates; bubble release ports disposed therein and arranged along a longitudinal direction of the top plate; and a bubble release chamber disposed in the housing and communicated with the bubble release ports. A folded-back path is formed by at least a folded-back plate and an inner plate disposed therein. One end and another end, respectively, of each of the folded-back plate and the inner plate in the longitudinal direction, are fixed to one of the two side plates and another of the two side plates, which face each other. One side and another side, respectively, of the folded-back path in the lateral direction are communicated with the bubble release chamber and a gas storage chamber.
