Membrantest
Membrantest refers broadly to experiments and procedures used to evaluate the properties and performance of membranes, including synthetic polymeric filtration membranes and biological membranes. It is not a single standardized protocol but a family of tests designed to quantify permeability, selectivity, mechanical integrity, and compatibility with feeds and cleaning agents.
Key properties commonly assessed include permeability (flux under defined driving force), selectivity or rejection of solutes,
Common testing methods include: pure-water permeability tests to measure baseline flux; solute-rejection tests using representative feeds
Standards and practice are provided by international bodies such as ISO and ASTM, with specific membrane testing
Applications span water treatment, food and beverage processing, biotechnology, gas separation, and medical devices.
Results are typically reported as flux and rejection or selectivity curves, often illustrating the trade-off between
Limitations include dependence on test conditions, lab-scale versus module-scale results, and differences between model feeds and
