5 Background in terms of membrane

6 State of the art - Ceramic NF-membranes inopor nano History Pore volume NF UF Support MF : Development Al 2 O 3 -supports, MF- and UF-membranes Pore size [µm] : Development of NF-membranes (HITK + RKV) : Pilot production of membranes on a semi-technical level (inocermic), first pilot membrane filtration plant (25 m²) 2005: Membrane production in full technical scale (inocermic + RKV) 2006: Foundation of inopor GmbH

7 State of the art - Ceramic NF-membranes inopor nano Morphology Material: amorphous TiO 2 Membrane thickness: 50 nm Pore size: 0.9 nm Open porosity: 30 % High temperature stability High pressure stability High chemical stability W & Au TiO 2 ZrO 2 TiO nm

8 State of the art - Ceramic NF-membranes inopor nano Retention behaviour Retention [%] Cut-Off 450 g/mol Molecular weight [g/mol] 0.9 0,9 nm TiO2 2 NF-Membran membrane 5 nm TiO2 2 UF membrane Membran

9 State of the art - Ceramic NF-membranes inopor nano Examples of application Waste water cleaning Waste Removal water of dye cleaning Decolouring Cleaning of inutec Cleaning Retention of of inutec catalysts Retention Separation of of catalysts aroma special properties of ceramic membrane opened field of application in several processes (very) large scale applications are hindered by high specific membrane costs ( /m²) Main reason: small membrane area per element

10 Objectives

11 Objectives Improve the efficiency of high performance water purification by ceramic membranes: strongly increase membrane area of ceramic NF membranes apply and test anti fouling layers to reduce fouling tendency develop process schemes for treatment of different waters Life cycle assessment, cost analysis, techno-economical evaluation Active participation of industrial partners: RKV (membrane manufacturer), VMW (end-user) and CYCLUS (OEM, end-user).

12 One focus: Complexity of Membrane support Pressure drop of permeate increases with complexity of support Development of geometry and membrane module is necessary

13 Consortium

14 Participants and consortium The CeraWater consortium consists of 8 European organizations (RTD, Large enterprises, SME) from 4 countries Research centers and universities: IKTS VITO UCA LUT Large enterprises: RKV VMW SME: CYCLUS ID IWW
