ultrafiltration (uf) is a membrane filtration process similar to reverse osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. The pore size of the ultrafiltration membrane is usually 103 - 106 daltons. Ultrafiltration (uf) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density.

ultrafiltration (uf) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.

ultra filtration plant is designed on the basis of 4 membranes or modules which are:

spiral wound module which less expensive yet more sensitive to pollution and consisting consecutive layers of large membrane
plate and frame module: combination of plates and membranes to improve the bad quality of water
tabular membrane: it is not compact and very costly as compare to others fluids discharge activities.
hollow fiber membrane: containing small tubes or fibers to carry out "inside-out" and "outside-in" filtration process.

Ultra Filtration System

Working Principle

Ultra filtration is a unique pressure-driven physical separation process in which the water is passed through porous (partially permeable) membranes with pore sizes in the range of 0.1 to 0.001 micron. These membranes are in the form of long hollow fibers. The result is high pure water free from physical and biological contaminations. Ultra filtration is not fundamentally different from micro filtration or neno filtration, except in terms of the size of the molecules it retains. Ultra filtration is utilized in two different operational modes such as Dead-End and Cross-Flow.

In Dead-End ultra filtration process, without circulation overall quantity of feed water is pressed through the membrane module; whereas, in Cross-Flow process the feed water passes parallel to the membrane face, one part is passed through membrane and other part is re-circulated to create turbulences over the membrane.
