INTEGRATED CARTRIDGE FILTER ASSEMBLY

WIPO Patent Application WO/2020/168847

A1

An integrated cartridge filter assembly, comprising an outer cartridge (1), a cartridge cover (2), a primary water channel (5), a filter membrane module (4), and a pre-filtering module (3). The pre-filtering module (3) filters raw water introduced into the pre-filtering module (3), and guides the filtered water from inside to outside into a first primary water layer located between the outer cartridge (1) and the pre-filtering module (3) so as to generate primary water. The filter membrane module (4) is used to separate the primary water introduced into a second primary water layer into purified water and concentrated water, wherein the second primary water layer refers to the space between the filter membrane module (4) and the pre-filtering module (3). The primary water channel (5) connects the first primary water layer and the second primary water layer. Compared with an existing single-use cartridge filter assembly, the invention provides two independent modules, namely the pre-filtering module (3) and the filter membrane module (4), thereby resolving the issue in which the different service lives of integrated cartridge filters and filter membranes result in wastage or poor efficiency, and reducing the use costs of integrated cartridge filter assemblies.
