Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to an ultrafiltration water purification device. Background Art

[0002] Ultrafiltration water purifiers utilize a membrane filtration method powered by pressure differentials through a composite filter element with an ultrafiltration membrane. These devices purify water using ultrafiltration technology. Existing composite filter element ultrafiltration water purifiers typically have filter elements bolted directly into the unit without a specific mounting structure. This makes the fixed filter element difficult to remove and clean. Over extended use, the filter element's surface can become covered with impurities trapped while removing suspended matter, colloids, and other impurities from the raw water. This can cause scale clogging, impacting the filter element's filtration effectiveness and resulting in substandard filtered water. Utility Model Content
