The so-called “thousand leaves” (or mille-feuille) paper is the world’s first non-woven filter, composed of 100% native cellulose, which is capable of removal of all types of microogranisms, including the “worst-case” microorganisms, i.e. non-enveloped small size viruses (18-22 nm), from water with high efficiency (log10 reduction value LRV > 5, i.e. >99.999%) and at industrially relevant flow rates (10-350 L m-2 h-1 bar-1). The name mille-feuille (pronounced [mil-fœj]) describes the unique stratified architecture of the filter paper consisting of hundreds of thin, stacked 2D nano-sheets reminiscent of the famous French mille-feuille puff pastry. By using a naturally derived raw material and simple manufacturing processes the filter paper has unrivaled potential to be be a cost-efficient solution for numerous applications.This proposal aims at the evaluation of the properties of the “thousand leaves” filter paper in real-life studies in collaboration with scientists at University of Dhaka and IDDR,B in Bangladesh for water treatment and clinical applications, respectively. The work in the project will target three main areas- raw materials evaluation, production and validation of upscaledproperties of the filter; evaluation of thefiltering ability for point-of use water treatment; and blood plasma filtration treatment studies.
