Publication number: 20210002158Abstract: A header-equipped air diffusion device can sufficiently suppress the intrusion of sludge into the air diffusion device from the header and allow stable operation even with repeated operating and stopping, and a membrane separation activated sludge device. The header-equipped air diffusion device can include an air diffusion device and a header which are immersed in water to be treated. The header includes an air storage unit, on the lower end of which is formed an inlet for the water to be treated, and an air supply part and an air sending part provided on the upper section of the air storage unit. The air sending part and a horizontal tube of the air diffusion device are connected, the air sent from the header is diffused by the air diffusion device, and an air sending of the air sending part in the air storage unit is positioned above an air supply port of the air supply part.Type: ApplicationFiled: September 24, 2020Publication date: January 7, 2021Applicant: MITSUBISHI CHEMICAL AQUA SOLUTIONS CO., LTD.Inventors: Yunje LEE, Makoto IDEGUCHI, Shinsuke FURUNO

Patent number: 10874996Abstract: To provide a nanobubble generating nozzle that is compact and capable of generating nanobubbles with high efficiency. The problem is solved by a nanobubble generating nozzle and a nanobubble generator including this nanobubble generating nozzle. The nanobubble generating nozzle includes an introduction part for introducing a mixed fluid of a liquid and a gas into an interior thereof, a jetting part for feeding out the mixed fluid containing nanobubbles of the gas, and a nanobubble generating structure part for generating nanobubbles of the gas, between the introduction part and the jetting part. The nanobubble generating structure part includes a plurality of flow paths having different cross-sectional areas through which the mixed fluid of the liquid and the gas is passed, in an axial direction of the nanobubble generating nozzle.Type: GrantFiled: January 3, 2019Date of Patent: December 29, 2020Assignee: AQUA SOLUTION CO., LTD.Inventors: Yukihiro Tsuchiya, Tomohiro Ota, Takahumi Goto
