[CEST2019_00520] Evaluation of Photocatalytic Materials for Water Purification: Overview of the New CEN Standard Test
by Triantis T.M., Kaloudis T., Hiskia A.

TiO2 photocatalysis offers an attractive alternative to conventional water treatment technologies leading directly to the degradation of organic pollutants, compared to transferring them from one phase to another as in the case of membranes or activated carbon. There is an increasing interest on using photocatalysis for water treatment, rendering reliable evaluation of performance of the catalytic materials necessary. Methods for testing photocatalysts used in water treatment are generally not harmonized.

[CEST2019_00532] Treatment of drinking water by UV/Cl2: a study of β-cyclocitral, a cyanobacterial taste & odor compound.
by Avagianos C., Antonopoulou M., Dimotikali D., Hiskia A., Kaloudis T.

Homogeneous photocatalytic processes are receiving increased interest with regards to drinking water treatment for emerging pollutants. Especially the UV/Cl2 technique has a potential for real large-scale applications as it can combine disinfection with chemical oxidation using processes that are more familiar and widely applied by water supplies.

[CEST2019_00516] Pollutant Photo-NF Remediation of Agro-Water
by Romanos G., Falaras P., Athanasekou C., Katsaros F., Markellou E., Georgaki E., Kizis D., Karanasios E., Anagnostopoulos C.

We describe the deployment of a novel water purification technology, which was initially conceptualized in the context of a readily successful FP7 project (CLEAN WATER, Grant Agreement no 227017, 2009-2012) and is now in the progress of been upgraded and upscaled thanks to the grants awarded by a LIFE Environment and Resource Efficiency project (LIFE PureAgroH2O, LIFE17 ENV/GR/000387, 2018-2021).

[CEST2019_00517] TiO2/CoFe2O4/Ag nanocomposites for photocatalytic reduction of water pollutants under UV and solar light
by Ibrahim I., Falaras P.

Novel ternary catalysts TiO2/CoFe2O4/Ag with variable ferrite content were synthesized, characterized and used for the photocatalytic reduction of Cr+6 pollutant, under UV and visible light illumination. Both TiO2 and CoFe2O4 were synthesized using the sol-gel method followed by hydrothermal treatment to prepare TiO2/CoFe2O4 (TCF) composite. Silver nanoparticles were successfully loaded on the surface of TCF to get three different composites, named as Ag/TCF. The crystal structure of the composites was analyzed by application of physicochemical characterization techniques.

[CEST2019_00437] Susceptibility of Algal Toxins to Advanced Oxidation Processes
by Dionysiou D., Duan X., Kong M.

Harmful algal blooms (HABs) occur more frequently and severely in recent years due to the climate change and increasing nutrient inputs, causing higher potential for the algal toxins to enter drinking water supplies. When HABs formation is intensive, conventional water treatment is insufficient to remove those toxins, so that further advanced technologies are necessary to be added.
