DEAD-END INCLINED ULTRAFILTRATION BY USE OF DYNAMIC MEMBRANES

Dead-end inclined ultrafiltration is examined, using a dynamic membran e comprised of fine particles formed on the microfiltration membrane b y dead-end downward filtration. The formation behavior of the dynamic membrane is described by the cake filtration rate equation in which th e compressibility of the cake is taken into account. A dynamically bal anced rate of filtration can be obtained by the inclined ultrafiltrati on technique, because the growth of the gel-cake can be significantly suppressed. If the membrane is inclined before enough cake to be exfol iated is formed, the dynamically balanced filtration rate is not influ enced by the time when the membrane is inclined.
