Ultrafiltration: Benefits, Applications, and How It Differs from Reverse Osmosis

Choosing between UF and RO? Here’s a clear, practical guide for whole-house and point-of-use applications. What is Ultrafiltration (UF)? • Benefits of UF • Best Applications (Whole-House & POU) • How UF Differs from RO • Which Should You Choose? What Is Ultrafiltration (UF)? Ultrafiltration is a membrane-based process that uses pores around ~0.01 microns . Under low pressure, water passes through a semipermeable membrane that retains suspended solids, bacteria, protozoa, and some viruses while allowing water and dissolved salts to pass. UF improves clarity and microbiological safety without altering mineral content. Key point: UF does not remove dissolved salts or most dissolved chemicals . It’s built for particulate and microbial control, not for high TDS or dissolved contaminants like nitrate or arsenic. Ultrafiltration: How it works and where to use it! Benefits of Ultrafiltration ...
