Microza Membranes |
Description
nnnnPolymeric Membrane Morphology
nnnnMicroza* ultrafiltration membranes are unique in their construction. Every
nnnnmembrane has an asymmetric structure,with a membrane layer both on the
nnnninside, and on the outside of the fiber, overlaying a core comprising a very
nnnnopen support for excellent flow characteristics, and a central strengthening
nnnnlayer for outstanding fiber durability in long-term service. Microza
nnnnultrafiltration membranes are resistant to flow In both directions, so there is
nnnnno risk of delaminatlon or membrane rupture during accidental back-
nnnnpressure. In fact, in many installations, backpulsing can be used to
nnnnmaintain flux during extended run times.
nnnnMicroza micofiltration membranes have smooth inner and outer membrane skins with a highly porous
nnnnsymmetrical support structure giving high-flow rates. These modules can also be backflushed. All Microza
nnnnmembranes have surfaces that minimize entrapment and facilitate cleaning. .All Microza membranes are
nnnnmanufactured in a single step, and are not composed of laminates. Membranes and modules are
nnnnsubjected to rigorous quality control to ensure consistency of performance, durability in service, and module
nnnnintegrity for the most demanding applications.
nnnnMembrane Types
nnnnPolysulfone (PS)
nnnnPolysulfone membranes exhibit excellent resistance to pressure, temperature and aggressive cleaning
nnnnregimes. Very low affinity and adsorption characteristics results in high product recoveries, and long service
nnnnlife.
nnnnFeatures
nnnnr Combination of high-strength and high-flow due to unique membrane construction
nnnn► Double-skin provides assurance of removal rating
nnnn► High-strength fiber allows reverse filtration to assist cleaning in difficult applications
nnnn* Available in arange of sizes from 0.015 m2 (0.16 ft2) to mere than 12 m2 C125 ft2}
nnnnf All SPandVP modules maybe hot water sanitized: up to 95 "C (203 CF)-SIP and SLP, or 90 CC (194 CF)
nnnn- SEP and SAP; and all may run continuously at 80 "C [176 °F)
nnnn► SP Modules maybe autcclaved in single use applications
nnnn► VIP 6000 MWCO version steam-sterilizable up to 50 cycles at 125 =C (257 T)ata differential pressure of
nnnn100 mBar
nnnnt SV modules are designed for maximized recovery in bulkfermentatlon, limited to 50 CC (122 °F)
nnnn* Compatible with a wide range of cleaning agents, up to 5000 ppm sodium hypochlorite or 4% sodium
nnnnhydroxide
nnnn► Meets the specification for biological tests listed In the current revision of USP for class VI plastics at 121 "
nnnnC [249 "F)
nnnn► pH range 1-14
nnnnPolyacylonitrile (PAN)
nnnnPAN membranes are ideally suited to bulk process applications, such as the purification of enzymes. They
nnnnexhibit high-strength, coupled with high flux rates, minimizing installation sizs. PAN has a lew fouling
nnnncharacteristic for these applications, simplifying cleaning.
