Chitosan Ultra-Thin Film Composite Nanofiltration Membranes

National University of Singapore, Singapore, Singapore

TECHNOLOGY SUMMARY

The technology relates to an ultra-thin high performance chitosan rejection layer over a polyethersulfone (PES) membrane support for heavy metal removal by nanofiltration(NF). The pure water permeability of the membrane is ~3.45 L/m2/h/bar and rejection to magnesium chloride, lead nitrate and nickel chloride is 96.3%, 93.0% and 96.3% respectively.

Primary Application Area: Environmental, Water & Waste

Technology Development Status: Prototype

Technology Readiness Level: TRL 3

FIGURES OF MERIT

Value Proposition: (1) Low cost materials used for the membrane; (2) High performance in separating heavy metals; (3) High water flux through the membrane (~3.45 L/m2/h/bar).
