Ultrafiltration System

Ultrafiltration (UF) is a membrane technique used to remove the dissolved and colloidal material in low transmembrane pressure. Dissolved metal ions as low-molecular weights or hydrated ions could easily transmit UF membranes, because their membranes have pores that are greater than dissolved metal ions.Ultrafiltration is the removal of fluid from a patient and is one of the functions of the kidneys that dialysis treatment replaces. Ultrafiltration occurs when fluid passes across a semipermeable membrane (a membrane that allows some substances to pass through but not others) due to a driving pressure.: Blood enters the glomerulus under pressure because the efferent arteriole is very narrow. Due to that pressure, it undergoes filtration, which is called ultrafiltration. Most of the particles get filtered; that is why it is called ultrafiltration.
