Produce water filter core structure

Technical Field

The utility model relates to the technical field of household water production equipment, in particular to a water production filter element structure.

Background

In the field of household water purification, various filter elements such as reverse osmosis filter elements, composite PP cotton and activated carbon filter elements in scenes are available, and ultrafiltration filter elements are also used in the field of household water production.

Ultrafiltration products are typically used for dead-end filtration where the filtered contaminants accumulate until the ultrafiltration membrane is replaced due to excessive accumulation of contaminants. External pressure type hollow fiber membranes are generally used, so that the capacity for pollutants is large; this scheme is similar to the traditional PP cotton filtration mode because of the accumulation of contaminants.
