Top Class Polymers: Reverse Osmosis
Reverse Osmosis
• Polysulfone is most commonly the middle layer in a three layer thin film
composite RO membrane
Typical composition:
trimesoyl chloride in solvent
m-phenylene diamine in water
Typical solution
in DMF or DMAc
Nonwoven
support layer
Polysulfone

Hemodialysis
• UF membranes used in dialyzers to treat
patients with renal failure
• The dialyzer performs the following
functions:
• Rid the body of wastes, such as urea, from
the blood
• Restore the proper balance of electrolytes in
the blood
• Eliminate extra fluid from the body
Hemodialyzer
(where filtering takes place)
• Sulfone polymers (PSU, PESU) are
utilized thanks to:
• Tailored grades compatible with PVP
• Medical Approvals ASTM F702-10 and
ISO 10993
• Ability to form fine UF hollow fiber
membranes with high manufacturing
productivity

Blood flows to dialyzer
Cleansed blood
flows back to body

Specialty Applications
• Membrane cartridges are utilized in several filtration
purposes for high end applications such as
biopharma, electronic industry, highly polluted industrial
wastewater treatment, air particulate and hot air
filtration
• These end uses requires high chemical and
temperature resistance due to the harsh conditions
of use and/or cleaning
Solvay portfolio includes high performing polymers for use in
extreme conditions
