2 Polymem The French membrane manufacturer and the 4 I : Independent / Innovative / Industrial / International Creation : 1997 Location: Castanet Tolosan (Toulouse FRANCE) About 50 people Membrane technology knowledge and expertise for water treatment applications: UF/MF, PSU/PVDF material Modules design Process design Approvals: ACS since 2007 and NSF/ANSI 61 since 2004 More than 300 installations worldwide Industrial partnerships Current developments for Gas membranes (gas separation) / Membrane contactors (CO2 capture). 2

3 Neophil New generation of fluorinated polymer hollow fibers Innovation = block copolymers anchored in a PVDF Kynar matrix Polymem, in partnership with Arkema has developed a new PVDF ultrafiltration membrane generation made from a new modified PVDF commercialized by Arkema under the Kynar PVDF name. The modification is based on a proprietary block copolymer which provides solid and durable anchoring in the PVDF backbone as well as local hydrophilicity to inner and outer membrane porosity. Furthermore its strong resistance to oxidation ensures the modification to be maintained during the entire lifetime of the membrane. 3

4 Neophil composition versus conventional PVDF membranes Conventional PVDF Membrane PVDF Neophil Membrane Porogen & hydrophilizing additives PVDF Polymer Additives Polymer Porogen & hydrophilizing additives PVDF Kynar DH100 Permanent Hydrophilicity 10 nm Miscible bloc to PVDF Hydrphilic bloc Chemical cleaning Water Chemical cleaning Water hydrophilicity irreversible Cl fouling Preservation of the hydrophilicity Cl Moderate irreversible fouling 4

5 Standard size distribution Neophil permanent efficiency constant hydrophilicity and constant removal efficiency Resistance to oxidants (chlorine, ozone ) High permeability C Excellent mechanical resistance Traction >6 MPa Elongation at break >160 % Mean pore size 15 nm Permanent characteristics and efficiency : No loss of performance in comparison of conventional PVDF membranes Virus removal / MS2 Phages : > 4 log on new fiber AND > 4 log on aged fibers (exposed to 200,000 ppm.h ph 7) Manual measurement Image processing Pore diameter (nm) 5

6 Relative Permeability Relative Flux Neophil performances Evaluated on seawater filtration in a TOTAL pilot platform, hosted by IFREMER at their Palavas-les-Flots research center on the Mediterranean coast 1,2 1 Fluxes Neophil TM membranes permeability always higher whatever the operating fluxes (compared to PSU). Despite very poor quality of inshore seawater entering the demonstration plant (fouling index SDI 15 >5), SDI 15 of ultrafiltrated seawaters always <2 thus meeting perfectly the NF and RO process requirements.

7 GIGAMEM Modules The most compact and economic ultrafiltration module range available Permeate Raw water Gigamem Out/In filtration Accepts high suspended solids concentrations Easy dead end process with reduced numbers of connections / valves In place maintenance (no module handling) The concept for large capacity plants Compacity Reduced maintenance & operation Reduced replacement cost (only the membranes) A vessel for each application 7
