Filtering film component

Abstract

The invention relates to an outside-in filtering membrane assembly (5) with long service life and capable of being filtered stably. Two ends or one end of multiple hollow fiber membranes (7) is fixed with sealing resin and are hold in a shell (8). The length direction of the hollow fiber membrane is arranged to be vertical to place the sealing resin part at the above part. The invention is characterized in that the space between the upper end (3a) of the upper drain discharge nozzle (3) at the side of the shell and the interface (4a) of the upper sealing resin layer (4) is above 10 mm; at least at the periphery part of the above hollow fiber member beam, the interface of the upper sealing resin layer to the outer surface of the upper drain discharge nozzle at the side of the shell of the hollow fiber member is coated with sealing resin. The upper end of the hollow fiber member of the filtering membrane assembly opens at the upper surface of the sealing resin and the lower part of the hollow fiber membrane does not open, with an introduction opening (10) capable of introducing gas and / or raw water.

Description

Filter membrane module technical field The present invention relates to a filtration membrane module used in a separation process such as precision filtration or out-of-limit filtration. More specifically, it relates to the purification of water used in the manufacturing process of various industrial products, such as river water, lake water, ground water, etc. Membrane filtration modules used in the production of tap water as raw water, in the water treatment process of domestic sewage, industrial wastewater, etc. Background technique It is used in the purification of water used in the manufacturing process of various industrial products, the manufacture of tap water using river water, lake water, groundwater, etc. as raw water, and the recovery of water after biological treatment of domestic sewage, industrial wastewater, etc. Separation processes by fiber membrane filtration are widely used. Fig. 3 shows the structure of a conventional membrane filtration module. In ...

AI Technical Summary

Problems solved by technology

Here, it was found that, in particular, by preliminarily forming a space at the upper sealing resin interface where the hollow fiber membrane is easily broken, so that water cannot be filled, the membrane at the upper sealing resin interface is not shaken, and the hollow fiber membrane during air cleaning is found. Fracture is greatly reduced, thereby completing the present invention
