Title of Process/ Know-how/ Product/Design/Equipment
Nanofiltration membrane for water softening by partial desalination, decontamination and disinfection
Application/Uses/Problem being addressed
Water purification by partial desalination, decontamination and disinfection
Salient Technical Features including Competing Features/ Impact
Low pressure nanofiltration membrane process based on indigenously developed high-flux nanofiltration membrane. It is ultathin-film composite membrane based on the cross-linked polyamide selective layer supported on a uniformly and highly porous support which exhibited the pure water permeability of 95-150 LMH at 150 psi, Na2SO4 rejection 99- 99.5 %, MgSO4 95-99 %, NaCl rejection 25±5 %
