ULTRAFILTRATION

WHAT IS ULTRAFILTRATION?

•Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.

• Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate.

ULTRAFILTRATION (UF)

HOW IT WORKS :-

•Ultrafiltration uses hollow fibers of membrane material and the feed water flows either inside the shell, or in the lumen of the fibers.

•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.

• When strategically combined with other purification technologies in a complete water system, UF is ideal for the removal of colloids, proteins, bacteria, pyrogens, proteins, and macromolecules larger than the membrane pore size from water.

BENEFITS

•No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment)

•Lower energy consumption is in comparison of nano-filtration or reverse osmosis

•Good and constant quality of the treated water in terms of particle and microbial removal

•Process and plant compactness

•Simple automation

•Environmentally friendly
