Process of colmatage in porous medium with closed circulation of suspension

Authors: A. Trzaska, K. Sobowska

In this paper a theoretical description of the phenomenon of colatage observed in a porous medium with a finite lenght "L" and a closed circulation has been presented.

Such circulation allows one to used the same suspension many times because after flowing through the medium, it can be forced again into it.

Theoretical considerations have been presented on the basis of a systems of balance-transport equation (1) and those of the kinetics of the colmatage process (2) with initial-boundary conditions (3), (4), (5).

Functions obtained determine the distribution of the concentration of flowing suspension "N" (x,t) (17) and the porosity epsilon (x, t) (18) in space x and time "t" of the proceeding phenomenon.

Based on equation of motion (20) the distribution of pressure in porous medium were determined (23).
