Ultrafiltration is a membrane-based separation process used to remove suspended solids, colloids, bacteria, and viruses from water. It operates using membranes with pore sizes ranging from 1 to 100 nanometers, ensuring high-efficiency filtration. UF systems are especially effective as a pretreatment stage before Reverse Osmosis (RO) plants. Known for their precise filtration—capable of filtering particles as small as 0.01 microns—they significantly reduce turbidity and outperform traditional media filters in clarity and performance.
