NP030 P

Summary

Product identification

The NADIR® NP030 is a polyethersulfone (PES) membrane exhibiting nanofiltration characteristics when exposed to high pressure. Its stabilized molecular weight cut-off is in the range of 500-600 Daltons after operation at 40 bar (580 psi). The NP030 membrane is durable enough for use in concentrated acid environments and caustic recovery systems. The membrane sheet is available in dry flat sheet rolls and is FDA compliant.
