Schematic diagram of a conventional and b crossflow filtration operation

Schematic diagram of (a) conventional and (b) crossflow filtration operation 

CEike), jj, is the viscosity of filtrate, and R is the resistance of the porous bed. The resistance R consists of resistance of medium, Rm and resistance of caJse, Rc. 

The resistance of cake is a function of voidage, e, the specific axea of paxticle, S and the cake thickness, 1. 

For incompressible fluids the e and S axe constant resulting in the following equation 

Equation 12.1 can be written in terms volmne of the filtrate as follows.
