2021年3月19日 · Membrane filtration is a technique for testing water samples. In this procedure, water is drawn through a special porous membrane designed to trap microorganisms larger than 0.45 μm. Afterward, the filter is applied to the surface of Endo agar plates and incubated for 24 hours. Endo agar is a selective media that encourages gram-negative
2018年9月19日 · In recent years, there has been a growing interest in utilizing inorganic membranes, particularly alumina (Al2O3) ceramic membranes (CMs), and to address a variety of separation problems in miscellaneous industry. Al2O3 membranes are commercially predominant in CMs market. Al2O3 material is generally used either as membrane support
