Because the RO filter element in the traditional composite filter element filters all mineral substances, but also filters and removes the good mineral substances of human body, the healthy and beneficial mineral substances can not be obtained in the drinking water of human body. Therefore, the technical scheme of replacing the RO filter core with the nanofiltration membrane and the chromatographic membrane provided by the invention can effectively filter heavy metals and retain part of beneficial minerals so as to achieve the technical effect of reasonable filtration.
The composite filter element comprises a preposed filter element (pretreatment filter element), a nanofiltration and chromatographic membrane (fine filter element) and a postposition filter element. The preposed filter element is as follows: the first-stage filter element is used for primary filtration and activated carbon fiber filter element filtration, and the PP filter element is used for pretreating the entering tap water and filtering silt, suspended matters, colloid and impurities in the water. The active carbon filter element is used for removing substances harmful to human bodies, such as heterochrosis, peculiar smell, residual chlorine, RouHua hydrogen and organic matters, and can be used for removing pollutants with the size of more than 10 microns. The active carbon fiber is soft paper-shaped, is rolled into a cylinder shape, is supported by the framework, and can increase the paper folding amount compared with paper folding and carbon rod matching in the delayed performance requirement, and the dirt holding amount is better.

The chromatographic membrane has larger water flux under lower driving pressure, and the removal efficiency of the nanofiltration membrane is greatly improved. Therefore, the conventional mineral ions can be retained and the heavy metal ions can be removed in the water purification process.
The third stage filter core is a post-positioned filter core, is a filter core made of a composite carbon material with a degerming function, and can be a silver-loaded activated carbon filter core. The water purifier is used for improving the water production taste (through carbon) and sterilizing (through silver), two-stage filtration is realized through one filter element, and the size of the filter element assembly and even the water purifier can be further reduced.
The front filter element can also be used for filtering a PP filter element, an active carbon filter element and a PP filter element, and then a layer of PP filter element is added for filtering so as to further filter suspended matters, colloid, impurities and the like in water. The water quality of the packed and filtered water meets the water quality requirement of the inlet water of the nanofiltration membrane. The activated carbon may also be a carbon rod.
The nanofiltration membrane can be an organic nanofiltration membrane or a ceramic nanofiltration membrane, and compared with the organic nanofiltration membrane, the ceramic nanofiltration membrane has the advantages of chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high temperature resistance, pollution resistance, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, simple and convenient operation and maintenance, long service life and the like, but the ceramic nanofiltration membrane and the processing difficulty and the cost are higher.
The post-filter element can also be activated carbon rod plus ultrafiltration/microfiltration, and the ultrafiltration can further sterilize and inhibit bacteria. To make the drinking water healthier.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention. The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
