Tubular Micro FILTRATION (TMF). What is TMF. Microfiltration (MF) is a low pressure ( 7 bar, 10-100 psig) separation process for separation of solids from aqueous solutions by means of a membrane. This crossflow process is carried out by having a process solution flow along a membrane surface under pressure.
