What is the primary function of an ultrafilter?

The primary function of an ultrafilter is to control and remove particulates and microorganisms from water. Ultrafiltration utilizes a semi-permeable membrane with specific pore sizes that allow water and small dissolved solids to pass through while effectively blocking larger particles, bacteria, and some viruses. This process is crucial in various water treatment applications, particularly where the removal of pathogens and suspended solids is necessary to ensure water safety and quality.

This function is essential because maintaining the microbial and particulate integrity of water is vital for both health and aesthetic reasons, ensuring that the treated water meets quality standards for consumption or other uses. In contrast, enhancing flavor, heating water, or filtering out chemical pollutants are functions that other treatment processes or technologies perform, but they do not represent the primary role of ultrafilters.
