Description

technical field [0001] The invention relates to an automatic membrane flux evaluation device and method, in particular to an automatic normal or tangential flow filtration device and method for membrane flux process analysis and development. Background technique [0002] For the purpose of purification (removal of particles or molecular pollutants) or concentration, the use of polymer membranes to filter liquid samples is an environmentally friendly technology that has been maturely used in the industry. For the purpose of such purification or concentration, the liquid sample flow through the membrane can be characterized as being substantially parallel (i.e. tangential flow, also known as cross-flow filtration) or substantially normal (normal flow, Also known as dead-end filtration), where the tangential and normal directions are relative to the surface of the filter membrane. [0003] Regardless of whether it is a dead-end or cross-flow filtration system, as the system ru...
