网页2022/05/26 · Uses of Membrane Filter (MF) Technique It is used to analyze a series of dilutions of water samples collected upstream and downstream from an outlet of a sewage treatment plant. EPA-approved guidelines for the determination of fecal contaminating organisms (EPA Method 1103.1) are routinely utilized worldwide to examine water
网页Membrane filters made of a colloidal polymer film are used in general particle filtration. They have a complex, open, colloidal-type structure, and in contrast to depth filters, mainly retain caught particles on the surface of the filter. Pore size is one of the most commonly discussed characteristics of a filter.
