Composite membrane filter

Abstract

The invention discloses a composite integrated membrane filter element. The composite integrated membrane filter element comprises a carbon ceramic tube membrane, ion exchange active carbon fiber membranes, brominated resin and a membrane core tube, wherein the membrane core tube is provided with a vertical tube part; the ion exchange active carbon fiber membrane, the brominated resin and the ion exchange active carbon fiber membrane are arranged in the tube cavity of the vertical tube part from the opening end to the other end in sequence; the carbon ceramic tube membrane covers the peripheral side of the vertical tube part; water penetrates from the carbon ceramic tube membrane and enters the inner cavity from the opening end of the vertical tube part of the membrane core tube, and flows out from a water outlet of the membrane core tube after being filtered and softened by virtue of the ion exchange active carbon fiber membrane, the brominated resin and the ion exchange active carbon fiber membrane in sequence, and remaining mineral substances in water are about 20%. The composite integrated membrane filter element disclosed by the invention is suitable for filtering northern drinking water with great hardness without losing mineral nutrients in water, and can be used for obtaining drinking water which is free of thermonatrite or water scales in the sensory, and relatively good in mouthfeel.

Description

technical field [0001] The invention discloses a composite integrated membrane filter element, which belongs to the technical field of filter element manufacturing according to the International Patent Classification (IPC). Background technique [0002] At present, most of the drinking water in the south of China is surface water with soft water quality, while the drinking water in the north is mostly ground water with high hardness. Water hardness (temporary hardness) refers to the content of Ca2+ and Mg2+ ions in water, that is, the carbonate content in water. Boiling can form water alkali or scale, which affects the taste of drinking water, and water alkali or scale precipitates (a layer and One layer) at the bottom of the water boiler, it is hard and difficult to dissolve, and it is not easy to remove. The water boiler reduces the service life. The above-mentioned white water alkali or scale is actually the carbonate precipitation of calcium and magnesium, which are mine...

AI Technical Summary

Problems solved by technology

Therefore, drinking water filtration and softening is the key to drinking safe water. The filter elements in the existing filter faucets are all suitable for the water quality in the south, while the drinking water in the north solves the problem of water hardness, and generally adopts reverse osmosis membrane or softener. This will filter out all the minerals in the water that are beneficial to the body, and drinking a certain amount of water-alkali dissolved in water is beneficial to the human body, and it takes four cups of water to purify a cup of water, which is costly
