Ultra Filtration (UF) uses membrane technology to reject contaminants from 0.01 to 0.2 microns. Compared to RO, UF filtration features a larger pore size, requiring a much lower operating pressure (10 to 100 psi) while maintaining higher flow rates (up to a maximum of 2 gallons/min). UF is effective in the removal of bacteria, pyrogens, high molecular weight dissolved solids and other water contaminants while allowing healthy minerals and ions through.
UF represents the most advanced filtration technology available. Compared to RO, UF provides bacteria and contaminant removal without the risk of bacterial contamination, the loss of healthful minerals, high levels of waste water, or a bulky storage tank.
