2022年5月26日 · The Membrane Filter (MF) Technique was introduced in the late 1950s as an alternative to the Most Probable Number (MPN) procedure for microbiological analysis of
2022年12月29日 · Ultrafiltration is a filtration process that uses a high pressure to force water through a membrane. Ultrafiltration has a tiny pore size of 0.1-0.01 microns, making it a good choice for removing tiny contaminants that pass through most filters. UF can remove contaminants as small as 0.025 microns from water.
