Reduces preparation time as compared to many traditional methods. Disadvantages of MBR process: 1. Microfiltration membranes retain particles according to the size of the pore, and the affinity of the filter materials for the solute. While materials are held largely on the surface of the membrane, they can also retain within the matrix itself, as in depth filtration. The process can be easily modified (pre-coating filter process). Advantage of Membrane Filter Technique The membrane can be transferred from one medium to another for purposes of selection or differentiation of organisms thus allowing isolation and enumeration of discrete colonies of bacteria. Usually about 100 ml of water is passed through a membrane filter (pore size 0.45 m). Spread Plate Method. No filter aids are needed, and the membranes have an extended lifetime. Almost all industrial membrane filtration is carried out as cross-flow filtration, where the liquid being filtered flows parallel to the membrane at high velocity and under pressure. .
