Filter-Medium Filtration Formulas

Constant-pressure drop filtration can result in saturation or blockage of the filter medium. The network of pores within the filter medium can become blocked because of one or a combination of the following situations  [Pg.173]

Proper filter medium selection is based on understanding these mechanisms and analyzing the impact each has on the filtration process. [Pg.173]

Consequently, the initial filtration rate per unit area of filtration is  [Pg.174]

Consider 1 m of suspension eontaining n number of suspended partieles. If the suspension eoneentration is low, we may assume the volume of suspension and filtrate to be the same. Henee, after recovering a volume q of filtrate, the number of bloeked pores will be nq, and the number unbloeked will be (Np - nq). Then the rate of filtration is  [Pg.174]

Equation 46 states that when complete pore blockage occurs, the intensity of the increase in the total resistance with increasing filtrate volume is proportional to the square of the flow resistance. [Pg.175]
