Embodiment Construction

[0029] will refer to Figures 1 to 3 The membrane modules, membrane units and membrane separation devices according to the embodiments of the present invention are discussed in detail.

[0030] In this embodiment mode, the membrane separation device of the system using the diaphragm separation activated sludge method (membrane bioreactor: MBR) in sewage and wastewater treatment facilities is exemplified; however, the membrane module and the membrane separation device according to the present invention are not It is limited to this embodiment, and therefore applicable to filtration of various treated water to be treated (the treated water is not limited to water, and thus may be an organic solvent, etc.).

[0031] Such as figure 1 As shown in , a membrane separation device 1 according to an embodiment of the present invention includes a membrane unit 2 and an air diffusion device 7 arranged below the membrane unit 2 to diffuse air, and the membrane unit passes more The membra...

Abstract

A membrane separation device wherein the occurrence of membrane clogging is minimized to reduce a load in a filtering operation. A membrane module (3) is configured by providing separation membranes (4) in a housing (6), which has openings in the upper and lower portions thereof, in such a manner that the separation membranes (4) are upright and are parallel to each other. A water flow guide (5) is provided to the membrane module (3) in the flow path thereof through which water to be treated flows, and the water flow guide (5) is provided so that the area (S2) of the opening of the flow path out of which treated water flows is less than the area (S1) of the opening of the flow path into which the water to be treated flows. Such membrane modules (3) are stacked on each other in the direction of the height of the housing (6) to configure a membrane unit (2). A membrane separation unit (1) is configured by providing an air diffuser (7) below the membrane unit (2).

Description

technical field [0001] The present invention relates to a membrane module, a membrane unit formed by stacking said membrane modules one on top of another and a membrane separation device provided with said membrane module or said membrane unit, and in particular to a membrane unit to be used in the field of water treatment membrane modules, membrane units and membrane separation devices. Background technique [0002] Membrane separation technology has hitherto been used for seawater desalination, water purification treatment, gas separation, blood purification, etc., among which, from the viewpoint of environmental protection, research has recently progressed to apply membrane separation technology to wastewater treatment. [0003] So far, sand filtering, gravity settling, and the like have been practiced as processes for achieving solid-liquid separation of treated water with high turbidity, such as water purification treatment, sewage, wastewater treatment, industrial wast...
