Abstract: A chromatographic separation method for separating plural components contained in a liquid to be separated by a chromatography, with a separating device 1 including plural filling portions 10 filled with a separating agent for separating the plural components contained in the liquid to be separated, a supply portion 20 provided in each of the plural filling portions 10 to supply the liquid to be separated or an eluent for extracting any component contained in the liquid to be separated to the filling portion 10, and an extraction portion 30 to extract any component contained in the liquid to be separated from the filling portion 10, the method including: an upward supplying and extracting step of extracting any component contained in the liquid to be separated from an upward stream extraction portion while supplying the eluent to at least one filling portion 10 from an upward stream supply portion by an upward stream.

Abstract: A plant cultivation apparatus including a conveyor that contains a conveying device for a cultivation bed and a blowing means that sends a flow of air to plants on the cultivation bed on the conveying device. The plant cultivation apparatus is provided with a space for causing the flow of air to pass between the cultivation bed adjacent in a conveying direction and pass through a bottom surface of the conveying device.

Abstract: A method for separating steviol glycoside, including: a separating step 55 of performing a continuous liquid chromatography for continuously separating at least one type of steviol glycoside by allowing a liquid to be separated containing plural types of steviol glycosides to pass through a separating agent in which polyethylene imine is immobilized to a carrier.

Abstract: 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.
