Sometimes liquid passes in a plug flow mode through a porous matrix such as soil, sand or porous rock. Biofilms initiated in such a matrix can be used to slow the rate of flow of contaminants through the matrix in what is called a biobarrier.n an ideal plug flow reactor, it is assumed that there is no mixing of the medium along the long axis (X-axis) of the reactor although there may be lateral mixing in the medium at any point along the long axis (ie the Y-axis).
