Ultrafiltration is a membrane based technology, which is used for separation of higher molecular weight particles from water. It can separate particles of even 0.01 microns from liquid ( i.e. Molecular weight 10KD to 100KD). Different membrane configurations and sizes are available for filtration requirements. Hollow fiber and Spiral wound configurations are most commonly used in the industry.The UF membranes have tolerance for free chlorine also they do not alter minerals compositions.
