Filter element for water filter treatment

Abstract

The invention relates to a filter element for water filter treatment. The filter element is characterized in that an inner-outer dual-layer filter structure is adopted, wherein the outer layer is a cheap flake-type filter membrane which can be detached for washing and changed, and the inner layer is an external-pressure hollow fiber ultrafiltration membrane which is high in filter fineness, excellent in performance, durable and practical; in the filtering process, rust and other stains in water are firstly removed by the outer filter membrane, and bacteria and other tiny particles are removed by the inner external pressure type hollow fiber ultrafiltration membrane, so that a dual-layer serial-connected filter structure is formed; the filtered water flows out from two ends of the filter element; when the filter element is blocked, the outer filter membrane can be washed or changed, and the inner membrane can be washed. The filter element has a better filter effect than that of an existing disposable filter element, can be detached and washed by users easily, is convenient to use, and has the advantages of durable effect, economy and environmental friendliness.

Description

technical field [0001] The invention relates to a filter core for water filtration treatment. Background technique [0002] Ions and oxides of iron, manganese, aluminum, silicon and other elements and organic compounds such as humic acids are the most common pollutants in tap water and all natural water. These pollutants generally pollute water quality in the form of turbidity, color, and turbidity, and are the first pollutants to be removed in water treatment. The easiest way to remove these contaminants is to filter them out with a suitable filter. However, these pollutants are often combined with the filter element or filter medium in the filter (filter materials made of PP material, chemical fiber material, ion exchange resin, activated carbon, etc., and microporous filter membranes made of various materials. ) react to form contamination that is difficult to clean from the filter element or filter media. Once these pollutions are formed, they will cause clogging of t...

Problems solved by technology

However, these pollutants are often combined with the filter element or filter medium in the filter (filter materials made of PP material, chemical fiber material, ion exchange resin, activated carbon, etc., and microporous filter membranes made of various materials. ) react to form contamination that is difficult to clean from the filter element or filter media

Once these pollutions are formed, they will cause clogging of the filter element or filter medium, making the filtration unable to continue

[0003] In order to solve the above problems, the current method is basically to replace the filter element (in case the filter element is blocked, replace it with a new filter element), which not only wastes resources and increases the amount of waste, but also increases the economic burden of the user, which is neither economical nor harmful.
