CECs and AMR bacteria pre-concentration by ultra-nano filtration and Abatement by ThermoCatalytic Nano-powders implementing circular economy solution. (NanoTheC-Aba)

This project will deliver an energy efficient new integrated prototype system for water purification, composed of three different components.

Ongoing project

The components are:

  • The first-to-be realised ultra-stable silicon carbide (SiC) UltraFiltration/NanoFiltration (UF/NF) membrane
  • An innovative nano-enabled Thermocatalytic energy efficient Packed-Bed Reactor (TPBR)
  • A nano-enabled antimicrobial MicroFiltration (MF) membrane.

The TPBR beads are obtained by recycling SiC membranes scraps deriving from the ordinary production process and will be coated with thermocatalytic perovskite-nano powders allowing full abatement of CECs and of AMR pathogens at mild temperatures without need of chemicals and light sources. The MF membrane is coated with antibacterial titania-silica-core shell nanoparticles for inactivating AMRbacteria, while removing suspended solids. The UF/NF membrane separates the clean permeate stream, ready to be recycled or reused from the toxic concentrate, which is purified by the TPBR, thus preventing discharge of CECs and pathogens in rivers and oceans.

The new system is compact, amenable to scale-up, and ease to integrate in mariculture, aquaculture, tannery, hospital, and other industrial wastewaters treatment facilities, providing safe and efficient operation. The integration of the three components allows the optimization of each system unit both alone and in combination, boosting the efficiency of the process and ensuring high water quality and safety, by enabling a water and SiC recycling multi-circular model
