Nontraditional constant pressure filtration behavior

Abstract

Pressure filtration is a common industrial process used for solid-liquid separation and laboratory technique used to measure the compressional rheological properties of suspensions. Traditional approaches to the modeling of constant pressure filtration behavior of particulate systems stipulate quadratic behavior of time with filtrate volume. However, this is not necessarily a fundamental attribute of pressure filtration, but rather a result of the assumptions made of the compressibility and permeability of the material. This work solves diffusion-type constant pressure filtration governing equations using a finite-difference technique to demonstrate that filtration, under certain circumstanc..
