Membrane (separating layer)

A diaphragm or membrane (about late Middle High German membrane , piece of parchment 'from latin membrane , pellicle') is a thin layer of a material which affects the mass transfer through this layer. Membranes occur in a wide variety of applications and functions.

Every biological cell is surrounded by a semipermeable membrane. Also the fascia , which cover the soft tissue components of the connective tissue, the body-internal areas of the whole body, like all collagenous fibrous connective tissue, in particular joint and organ capsules, tendon plates, muscle septa, ligaments, tendons and other, as an enveloping and connecting tension network Membranes.

In separation technology, membranes are used as a separating layer in membrane technology .

Membranes have different permeability:

• impermeable
• selectively permeable
• unidirectional permeable
• omnipermeable
