CSM NF MEMBRANE, The approved Nanofiltration membrane in the whole world
NE4040-90
Nanofiltration membrane element with high monovalent ion rejection
Features
CSM NE90 elements with 90 % monovalent ion rejection and more than 99 % rejection of divalent ions are useful
for water softening, removing endocrine disruption chemicals from drinking water and also food processing in
small size systems.

Design Guideline for Various Water Source
Waste water ( SDI < 5) 8 ~ 12 gfd
Waste water pretreated by UF ( SDI < 3) 10 ~ 14 gfd
Seawater, open intake ( SDI < 5) 7 ~ 10 gfd
High salinity well water ( SDI < 3) 8 ~ 12 gfd
Surface water ( SDI < 5) 12 ~ 16 gfd
Surface water ( SDI < 3) 13 ~ 17 gfd
Well water ( SDI < 3) 13 ~ 17 gfd
RO/ UF permeate ( SDI < 1) 21 ~ 30 gfd

Saturation Limits for Salts
CaSO4 230 % saturation
SrSO4 800 % saturation
BaSO4 6, 000 % saturation
SiO2 100 % saturation
⢠Above values are saturation limit at the tail end of the membrane elements for each sparingly soluble salts with proper scale inhibitor

CaCO3 Scaling potential limits as LSI or SDSI
Without scale inhibitor < -0.2
LSI ( SDSI) with SHMP < + 0.5
LSI ( SDSI) with special inhibitor1 < + 1.5
SDSI with any inhibitor < + 0.5
⢠Special inhibitor means one of approved organic inhibitors. It should be approved from real plant for more than three years.
