Filtration is a physically or mechanically separation process in which suspended solid particles in a fluid are removed by using a porous medium that retain the particles as a cake and passes the clear filtrate. The porosity distribution and filtrate production during cake filtration in a plate-and-frame filter press were simulated mathematically. The model considered filtration that occurs after the filling process, not filtration that occurs as the suspension fills the cell. Operational equations and theoretical calculation K, s, C, m were developed for a plate-and-frame press.
