Characteristics of ultrafiltration

Thread Content

Features of ultrafiltration: Compared to traditional purification methods, ultrafiltration offers many advantages:  It can completely remove microorganisms and particles. Removal rates for pollutants in water are as follows: PM10 – 99.8%, PM100 – 99.0%; colloidal silicon – 99.8%, 99.0%; colloidal iron – 99.8%, 99.0%; colloidal aluminum – 99.8%, 99.0%. Suspended solids: 5 LRV, 4 LRV; turbidity: < 0.3 NTU (usually less than 0.1 NTU); SDI: < 1.0. Giardia: 6 LRV, 5 LRV; protozoa: 6 LRV, 5 LRV; bacteria: 6 LRV, 5 LRV; viruses: 5 LRV, 4 LRV; endoviruses: 4 LRV, 2 LRV. TOC: average of 70%, average of 30%.  The filtering efficiency is not affected by the quality of the raw water.  It can remove chlorine-resistant pathogens.  The concentrate produced by ultrafiltration contains only those substances that were originally present in the water.  Compared to other traditional methods, ultrafiltration results in significantly less sediment.  The compact design of the units allows for better use of space, reducing costs; it also enables flexible installation within existing facilities.  Ultrafiltration enables fully automated continuous industrial production.  Since ultrafiltration can almost completely remove the substances that form the coating layer, it is possible to increase the area load in subsequent membrane purification steps, thereby reducing the size of the subsequent purification equipment.
