Improve wastewater treatment management through innovative, efficient and environmentally
friendly technology to obtain treated water free of emerging pollutants (EPs). To do this, we will
develop and validate a system that eliminates EPs and other pathogens from wastewater that will
consist of an adsorption system of cyclodextrin polymers (CDs) coupled with advanced oxidation
processes (AOP).
The designed technology will be tested in a
WWTP where wastewater will be collected
continuously and introduced into a filter filled
with adsorbent material of Cyclodextrins.
02
At the outlet of this adsorption process, a photocatalysis unit will be installed to remove by oxidation any remaining pollutant that is not retained.
03
The cyclodextrin desorption product full of
pollutants will be accumulated in a reject tank
for further treatment by means of a pulsed
light system that will destroy the pollutants
that were adsorbed by the CDs.
04
The application of this treatment system in a WWTP will be of demonstrative character and will allow its application in other WWTPs in order to remove EPs from the outgoing wastewater.
Laboratory prototype
Semi-industrial prototype
o Tests carried out so far have shown that the proposed
combination of technologies is able to remove up to
90% of EPs present in treated wastewater, both
pharmaceuticals and phytosanitary products.
o The ultrafiltration stage, after the water has passed
through the CDs, ensures and maintains the
disinfection of the wastewater, complying with EU
Regulation (2020/741), while increasing the useful life
of the CDs, which have a high number of cycles.
Assessment of the technical
and economic feasibility of
the proposed technology for
its commercialisation and
implementation at industrial
level.
