A New Generation of Fine Fiber Processing for Filtration
Electrospun Filter Media for Gas and Liquid Filtration
The aim is to show various methods how we can use unique properties of electrospun nanofibers to reduce dangerous substances in combustion gas, atmospheric air and industrial liquids. The development focuses on nanofiber materials, functionalized polymers and specific fibril structures. Main relations between filter media parameters and final product properties were observed. The main research topics covered by the presentation are:
• Filtration of solid substances from atmospheric air in ventilation systems or for personal protection,
• Antimicrobial modification of atmospheric air filters,
• Cleaning hot or cold gaseous combustion products by using catalytic agents,
• Membrane filtration of different heavily polluted waste water,
• Purification of drinking and non-potable water using regenerable nanofibrous membranes or disposable cartridges with composite nanofiber yarn.
