Matlab software, a mathematical model of the wort filtration performance and granularity relationship was established, which is applicable for predicting and improving the wort filtration performance. The granularity distribution and percentages of particle numbers and volumes of the wort before and after filtration had great impact on the wort

Numerous mathematical models have been developed to evaluate both initial and transient stage removal efficiency of deep bed filters. Microscopic models either using trajectory analysis or convective diffusion equations were used to compute the initial removal efficiency. These models predicted the removal efficiency under favorable filtration conditions quantitatively,

interesting opportunity is given by exploiting the internal filtration (IF)/back filtration mechanism that occurs spontaneously in highflux dialyzers, but is difficult to quantify. In view of overcoming this drawback, a semiempirical, lumpedparameter mathematical model for characterization of IF phenomena was developed. The model considers a dialyzer as

greatest difficulty arising during crossflow microfiltration is the formation of a cake layer on the membrane surface (also called fouling), thereby affecting system performance. Fouling has been related to permeate flux decay resulting from changes in operating variables. Many articles have been published in an attempt to explain this phenomenon but it has not yet

In mathematics, a filtration is an indexed set S i of subobjects of a given algebraic structure S, with the index i running over some index set I that is a totally ordered set, subject to the condition that if i ≤ j in I then S i ⊆ S concept dual to a filtration is called a cofiltration.. Sometimes, as in a filtered algebra, there is instead the requirement that the be subalgebras

In this presentation we will consider a filtration process governed by the Darcy fluid flow equations, coupled with an equation for the changing porosity (permeability) of the medium. Of particular interest is to determine a ``reasonable'''' mathematical model which permits a solution for the fluid velocity and pressure in the H_{div} and L^{2
