METHOD FOR HOISTING MEMBRANE SEPARATION DEVICE |
摘要 |
A method for lifting a membrane separation device immersed in liquid to be treated so as to obtain permeated liquid passed through a filtration membrane provides a method for lifting the membrane separation device in a visible state without lowering the liquid level of a treatment tank. The method includes injecting a gas into a predetermined region of the membrane separation device, thereby raising the membrane separation device by a buoyancy generated by the injected gas through the liquid to be treated, and engaging an engaging portion of a lifting apparatus with an engageable portion provided to an upper portion of the membrane separation device, thereby lifting up the membrane separation device. The predetermined region may be a space constituting a flow path for the permeated liquid permeated through the filtration membrane. |
