Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, and more specifically to a hollow fiber ultrafiltration equipment. Background Art

[0002] Hollow fiber ultrafiltration equipment is an advanced liquid separation technology, and its core component is the hollow fiber membrane. This membrane has a unique structure, with both the inner and outer walls open, forming many tiny channels. The hollow structure of these channels allows liquids to pass through efficiently, while achieving separation and purification of substances. When liquid flows through these hollow fiber membranes, smaller molecules and ions can pass through the membrane wall, while larger particles, bacteria, viruses, etc. are trapped on the outside of the membrane. This selective filtration effect makes ultrafiltration technology widely used in many fields, such as drinking water treatment, industrial wastewater treatment, biomedicine, etc.
