Introduction
TEXTILE MATERIAL ?
Today : Textile and Water
Veolia Hydrotech Filter Filters using woven
polyester mesh (10 to 1000 micron)
Veolia 3FM Filters using polyamide
fibers from 40 to 100 microns
WASTE WATER TREATMENT
New textiles solutions ?
Fine fibers generate pores and surface area
Jongchul Park, Finetex EnE, Filtrex 2010
Micron Fibers Sub-Micron Fibers
Nanofibers

Special Shape Fibers
P84™
4DG™
Specific surface area vs. Denier per
filament
Procon™
Allasso ®
Objective :
Increase specific
surface area
Special Shape Fibers :
– P84™ (Inspec)
– Procon™ (Toyobo)
– 4DG™ (FIT)
– Allasso ® (Allasso Industries)
Textiles Associations
Nonwoven with variable porosity: “gradient composite” Combined Filtration
Porosity gradient filter
Functional Textiles
Hydrophobicity/Oleophobicity with Vacuum Plasma
Heavy Metals Particles catched by Cyclodextrins
Conductive textiles or sensors textiles
Cyclodextrins Cage molecules for active compound
Water Textile Sensor (ENSAIT)
Nanofics Hydrophobic Textiles (Europlasma)
Development in UP-tex cluster ?
New Filtration media for liquid
clarification
FUI Program : 2013 – 2017 Budget : 2 956 k€ Objectives : enhance filtration properties by - Combining different medias - Reach submicron fibers and high porosity
R&D Project at UP-tex
DEPOLTEX Project
Development of depolluting geotextiles for the treatment of dredged sediments
Consortium :
FUI Program : 2011 - 2015 Budget : 3 393 k€
Objectives : - Graft biobased polymers onto geotextiles to interact with heavy metals ions
R&D Project at UP-tex
Innovative Methods for Mud
Dehydratation
FUI Program : 2014 - 2018
Budget : 1 493 k€
Consortium :
Objectives :
- Develop a conductive textile filter for applying an electric field to
increase performance of mud dehydratation by press filter
