  • 3. Main technologies Photocatalysis for water treatment Objective  New photocatalytic materials with enhanced properties  Study of photocatalytic fundamentals under real environments Technology’s key parametres  Photocatalytic coatings based on nano-TiO2 • Synthesis via sol-gel  high versatility to adapt to different substrates and to include different NPs • Strong adhesion to substrates: no need of posttreatment filtration • Strong resistance to leaching  Composite graphene-metal oxide platelets • Patent pending synthesis method (WO2011/132036 A1) • Improved photoactivity due to:  High surface area (nanoparticles dispersed on both graphene surfaces)  Reduced rate of e- hole recombination  Adsorption of chemical species on the surface (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).
  • 3. Main technologies Patent pending photocatalytic reactor Objective  Development of a robust, efficient and cost effective photocatalytic reactor for the elimination of emerging organic pollutants from water  Applicable as a tertiary treatment to urban and industrial wastewater and to drinking water. Technology’s key parametres  Complete mineralization of organic pollutants: no degradation subproducts  No chemical consumables  Based on TiO2 nanoparticles supported in coatings  Patent pending photoreactor with a maximized degradation efficiency (WO2012/156548 A1)  Collaboration with Oxital and University of Cantabria  Work in progress to increase photoreactor’s efficiency (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).

  • 3. Main technologies Pollutant adsorption by polymeric beads Objective Technology’s key parametres  Synthesis of functionalized adsorbents supported in polymeric beads  Taylor made solutions to selectively extract pollutants in trace concentration from water  Solid liquid extraction of pollutants from water: functionalization of macroporous polymeric beads with different functional groups (physic adsorption, covalent or ionic bonds). Examples: ZrO2 can extract fluoride, As and Se Zirconium phosphate can extract Pb (II) Chromotopic acid to extract borate Maleic anhidride with cysteine selective to Pb (II) and Cd (II) • Other pollutants such Se(IV), Al, or Cu (II), can also be effectively extract from water in trace levels • • • •  Enhanced surface-volume ratio by supporting the adsorbents in macroporous polymeric beads  Stability: adsorption of pollutants are not affected by interfering ions (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).
  • 3. Main technologies Membrane technologies Objective  Improvement of current processes: industrial wastewater treatment and effluent minimization  Recovery of valuable materials from wastewater for recycling Technology’s key parametres  Pervaporation • Elimination of VOCs from drinking water • Recycling of phenols from wastewater  Liquid-liquid extraction • Formaldehyde, phenol and methanol recycling from wastewater from phenolic resins fabrication  Membrane technologies (ultrafiltration, nanofiltration) • Membrane functionalization for the recovery of specific substances • Filtration of nanoparticles (TiO2, ZnO and Ag) • Membrane technologies (ultrafiltration, nanofiltration) Filtration pilot plant (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).
  • 3. Main technologies Electrochemical processes Technology’s key parametres Objective  Two main techniques:  Removal of redox active metals and metalloids from wastewater  Recovery of pure metals for recycling  Ions (metals) selectivity and versatility • Potentiostatic deposition: metal ions in solution are reduced by applying a constant potential to the metal electrode (cathode) • Cementation: metal ions are reduced to zero valence at a solid metallic interface.  Environmental compatibility: the main agent used is the electron, which is a clean reagent.  Cost effectiveness: simple and relatively inexpensive equipment and operations Schematic of an electrochemical cell Electrochemical cell  Amenability to automation: variables used (current, I, and voltage, E) are well suited for easing data acquisition, process automation and control.  Elimination of pollutants from a variety of industrial wastewater (i.e: painting processes, photographic processes, bleaching processes) Lab scale: Pure Cd deposited over Al cathode (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).
  • 3. Main technologies Ionic liquids Technology’s key parametres Objective  Removal of organic and inorganic pollutants from water  New coatings as corrosion inhibitors, antiscalants, biocides, algaecides and bactericides  Improvement of coagulation and flocculation during removal of solids in suspension from wastewater  Solid liquid extraction of pollutants from water • Incorporating functional groups ILs are capable of interacting selectively with the pollutant into solid materials: extraction of fluoride, As, Se, Bo, Pb(II), Cd(II),... • The extraction process with methimazole based ILs does not require the addition of a complexing agent or pH control of the mixture  Highly tuneable • ILs can be tailored to have selective functional groups. • Functionalized ILs can be impregnated in porous supports for water purification (i.e. membranes, polymer beads).  Cost effective • Ionic liquids can be recycled and used again in a cost effective process • Easy to synthesize in large scale • Environmentally friendly (no eco-human toxicity) (CONFIDENTIAL - Disclosure or reproduction without prior permission of Tecnalia is prohibited).
