摘要： The invention relates to a membrane filter for operating while submerged, with a frame (1), which can be lowered into the liquid to be purified, and with modules (2) adjacently arranged in a row. The modules (2) each have a base element (3) with a permeate collecting chamber (4), tubes (5) for a fluid that are connected to both ends of the base element (3), and with hollow fiber membranes (6) that, with an open end, are embedded in the base element (3). The hollow fiber membranes (6) are closed at their other end and terminate inside the liquid to be purified without being fixed whereby being able to freely move. The tubes (5) are vertically oriented and, at the top, are connected to a collecting line. Fiber holding devices (7) for laterally guiding the hollow fiber membrane (6) are fastened to the tubes (5). According to the invention, the fiber holding devices (7) are provided in the form of U-shaped brackets that have a web (8) and limbs (9), which are located at the ends of the web and can be fastened to the tubes (5), and these brackets surround the hollow fiber membranes (6) of a module (2) on one side in the longitudinal direction and, due to a correspondingly large dimensioned limb length, also surround the membranes at the ends in front of the tubes (8).

摘要： The invention relates to a membrane module for an immersed operation with a fibre bundle (1) of a large number of hollow fibre membranes (2) which with an open end are cast into a headpiece (3) and in immersed operation are surrounded by a liquid to be filtered, having a permeate collection chamber (4) connected to the headpiece with at least one permeate outlet (5) for the permeate draining from the interior of the hollow fibre membranes and a gas supply (6) having a pipe (7) guided by the headpiece. The pipe (7) terminates in the interior of the fibre bundle (1) and has a gas outlet (8) for a gaseous medium which after the transfer from the pipe (7) to the liquid to be filtered largely rises between the hollow fibre membranes (2) of the bundle as bubbles. According to the invention the fibre bundle (1) is divided into sections (11) each comprising a group of hollow fibre membranes (2). Free spaces (12) remain between the sections (11) which extend from the pipe (7) to the outer circumference of the headpiece (3) and promote an inflow of the liquid to be filtered into a foot area of the fibre bundle (1) adjoining the headpiece (3).

摘要： The invention relates to a method for aerating a number of membrane modules of a membrane filtering installation operating in a submerged area. Air or a gas is supplied from a common source to the membrane modules and rises in the form of bubbles in the liquid to be purified. On-off valves are placed in the supply lines leading to the membrane modules whereby enabling or preventing the supply of air to an assigned membrane module. In a first method step, when all other membrane modules are closed, the on-off valve assigned to a first membrane module is additionally opened. At the beginning of a second method step, the on-off valve assigned to a second membrane module is opened whereby causing the formation of two partial air flows. At the beginning of a third method step, all membrane modules are aerated in succession until the aeration cycle in the first membrane module starts again.
