IPR Status & Details:

IN 201811031932

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 %

TRL Level & Scale of Development:- TRL 5 TRL Reference

Prototype/ demonstration unit completed. Membrane preparation in the scale of 50 sq. m.; Spiral wound membrane modules of 4”×14” and 4”x 40”
