Information @ a Glance


  • The membrane can be defined essentially as a barrier, which separates two phases and restricts transport of various chemicals in a selective manner.

  • A membrane can he homogenous or heterogeneous, symmetric or asymmetric in structure, solid or liquid, can carry a positive or negative charge or be neutral or bipolar.

  • In medicine, microbiology, cellular physiology and biochemistry a membrane is a thin layer that separates various cellular structures or organs. It usually includes lipid bilayer reinforced by proteins and other macromolecules.

  • All eukaryotic cells contain elaborate systems of internal membranes which set up various membrane-enclosed compartments within the cell.

  • Peripheral Membrane Proteins more loosely associated with the membrane. They are usually attached noncovalently to the protruding portions of integral membrane proteins.

  • The membranes that surround the nucleus and other organelles are almost identical to the cell membrane. Membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure.


  • Membranes are highly organized and asymmetric having two faces with different topologies and different functions. Membranes are also dynamic, constantly adapting to changing environmental conditions.

  • The concentration of solutes, sugars, ions etc. are much higher within the cell than outside. The cell membrane prevents free flow of material and thus serves as an osmotic barrier.


  • Membrane technologies are commercially available for hydrocarbon processing operations such as removal of CO2/ H2S from natural gas and dehydration of natural gas. However, these technologies are  hampered by such limitations as performance degradation, high energy consumption, hydrocarbon losses, equipment complexity, and high initial-purchase costs.

  • A new membrane technology promises lower operating costs, improved reliability, lower maintenance needs, and reduced environmental impact for hydrocarbon separations.


  • U.S. membrane market is estimated at $1.6 billion dollars. Growing at AAGR (average annual growth rate) of 8.3% annually.

  • Ultrafiltration (UF), a $248 million market, is growing at an AAGR of 7.6%. Widely used in the booming pharmaceutical and biotech fields, UF membranes continue to improve and find new applications.

  • Microfiltration (MF) membranes, used mainly in drug and electronics manufacture, are a $707 million business growing at 9.0% on average per year. MF membranes also dominate in the expanding field of medical membrane devices such as hemodialyzers, blood oxygenators, IV filters and diagnostic kits.
