TriSep TS80 Membrane is a polyamide nanofiltration membrane with a nominal monovalent ion rejection of 80-90% and >99% rejection of divalent and polyvalent ions. As a result TS80 is considered a “softening” membrane with a typical feed pressure of about 100 psi. TS80 has a molecular weight cut-off between 100-200 Daltons, enabling it to also have high rejection of uncharged organic solutes.
TriSep TS40 Membranes are primarily used in food & dairy and other process applications to separate, purify and desalt organic solutes. TS40 is a piperazine-based nanofiltration membrane with a molecular weight cut-off between 200-300 Daltons. Typical applications include demineralization of whey or lactose, sugar concentration, or separation and UF permeate desalting.
TriSep XN45 Membrane is used for both process streams as well as low pressure water purification. XN45 is a piperazine-based nanofiltration membrane with a molecular weight cut-off of approximately 500 Daltons. Its nominal solute rejection is 10-30% for NaCl and greater than 90% for MgSO4 and sucrose. Typical applications include demineralization of organic solutes, processing of dyes, and organic separations.
TriSep UA60 Membrane is a piperazine-based thin-film composite membrane that is considered both a “tight” UF membrane as well as an “open” or “loose” NF membrane. UA60 has limited monovalent salt pore size and MgSO4 pore size between 70-90%. UA60 has a molecular weight cut-off between 1,000-3,500 Daltons. Due to its unique properties, UA60 is used in process applications requiring a “tight” ultrafiltration membrane or a very “open” nanofiltration membrane.
TriSep SB90 Membrane combines the chlorine tolerance of a cellulose acetate membrane with the high polyvalent ion rejection and lower pressure requirements of a nanofiltration membrane. SB90 elements are primarily used in beverage applications where residual chlorine is desired to protect against biogrowth.
