DIALYSIS
If such a mixture is placed in a sack made of parchment,
collodion, or cellophane and suspended in water, the ions and
small molecules pass through the membrane, leaving the
colloidal particles in the sack. Separation by dialysis is a slow
process, depending for its speed on the differences in particle size and diffusion rates between
REVERSE OSMOSIS
The process of reverse osmosis forces the water with a
higher concentration contamination into the tank containing
water with lower concentrations .A high-pressure water is
used to "transform" the natural osmotic process, with the
semi-permeable membrane, it allows the passage of water
and reject most of the other ingredients. Ion exclusion
process in which the concentration of ions in the surface
membrane of the barrier allows other water molecules to pass through and not including other
materials
GAS PERMEATION
Gas Permeation is one of separation process which involved
at least two components where those are fed to the
membrane that has a higher permeation flux for at least one
of the components in the feed mixture.The difference in
partial pressure between the feed side and the permeate side
of the membrane acts as a driving force for components to
permeate.Hence, the permeate side of the membrane is maintained at a substantially lower
pressure than the feed side.In the gas permeation process, the operating pressures may be
very high. Therefore, there may be substantial differences in the feed, retentate, and
permeate temperatures due to the Joule-Thompson effect.
ULTRAFILTRATION
Ultrafiltration with an abbreviation of UF and it is
commonly used in cross-flow or dead-end mode of
separation application in industry such as purifying
of proteins solutions or any process that require

macromolecular purification of continuous systems.It works by which hydrostatic pressure
forces a liquid against a semipermeable membrane.Suspended solids and solutes of high
molecular weight are retained, while water and low molecular weight solutes pass through the
membrane.The retained substances used are captured on the membrane surface and removed
from the module continuously or periodically, depending on the filtration mode type and
considering whether it is concentrate or in the backwash effluent.
REAL APPLICATION OF THE MEMBRANE IN THE INDUSTRY
Membrane Technology and Research, Inc. (MTR), based in Menlo Park, CA, is a privately
owned developer, manufacturer, and supplier of customized membrane process solutions.
MTR was founded in 1982 as an R&D company with a long-term goal of developingmarketable membrane technologies, especially in the newly-emerging field of industrial gas
separations.MTR is a world leader in the development and production of membrane-based
separation system fot the petrochemcial,natural gas and refining industries. The MTR group
conducts application analyses, develops process designs, and manages field tests of
innovative membrane systems.Ultrafiltration membrane process is used in this production.
Recently the development principle membrane product of this company is include the
following:
• VaporSep®
systems to remove organic vapors from air and nitrogen
•NitroSepTM and fuel
gas conditioning systems for natural gas treatment
• Hydrogen recovery systems for refinery and other applications MTR’s current R&D
extending use of membranes to carbon sequestration and biofuels separations.
