Development of a non-target screening workflow for the evaluation of micropollutants fate during oxidation processes
(Corresponding) Huynh N., Le Roux J., Guyot J., Moilleron R.
Topic:
Emerging pollutants
Non-target screening (NTS) is of great interest for environmental monitoring because it enables the screening of numerous pollutants, including unknown products. However, methods to identify unknowns are still time-consuming and only deal with a limited portion of the signal. The objective of this...Read more
Degradation of refractory compounds in industrial wastewaters by advanced technologies based on electrochemical and photochemical oxidation
Petsi P., Sarasidis V., (Corresponding) Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
Results are presented of a systematic experimental investigation aiming to eliminate refractory organics from industrial effluents, of high and non-biodegradable organic load, by two Advanced Oxidation Processes (AOPs). Bench scale experiments were performed with real wastewater samples collected...Read more
How to estimate biocide mass loads in urban water discharges and their impact on the river contamination?
(Corresponding) BRESSY A., PAIJENS C., TEDOLDI D., FRERE B., MAILLER R., ROCHER V., MOILLERON R.
Topic:
Emerging pollutants
Biocidal substances are ubiquitous in urban areas; they are used as preservatives in daily products, building materials, and as domestic pesticides. Despite these facts, urban sources of biocides, contrary to agricultural inputs, have been overlooked in terms of environmental risk assessment. The...Read more

Preliminary Research on Removal of Organic Substances Contained in Wastewater from Plastic Lenses Production
(Corresponding) Umiejewska K., Różycki M.
Topic:
Advanced oxidation processes
More than 80 percent of all eyeglasses worn today have plastic lenses. Plastic lenses made of polycarbonate discs are created through the process of machining which requires the use of a coolant. During the production process, the rotating disc and blade are poured with a mixture of water and...Read more
Monitoring illicit stimulant drug use in Cyprus during the COVID-19 lockdown by UPLC-MS/MS

Topic:
Wastewater-based epidemiology to monitor covid-19 outbreak: present and future diagnostic methods to be in your radar
The occurrence and spread of the novel corona virus SARS-CoV-2 at the end of 2019, has led WHO to announce the outbreak of a pandemic. Restriction measures were taken from authorities globally, in order to impede its spread. In Cyprus, a strict lockdown period was implemented on the 24th March of...Read more

SELECTED APPLICATIONS of CAVITATION BASED ADVANCED OXIDATION PROCESSES (AOPs) for TREATMENT of WATER and INDUSTRIAL EFFUENTS
Fedorov K., Cako E., (Corresponding) Boczkaj G.
Topic:
Advanced oxidation processes
Cavitation phenomenon was effectively applied for enhancement of Advanced Oxidation Processes (AOPs) effectiveness. Main applications are focused on treatment of water as well as industrial effluents [1-2]. Cavitation phenomenon can be generated in the liquid by intentionally formed differences in...Read more
Monitoring of SARS-CoV-2, noroviruses and adenoviruses in wastewater in the Czech Republic
(Corresponding) Mlejnková H., Sovová K., Vašíčková P., Gharwalová L., Očenášková V., Jašíková L., Juranová E.
Topic:
Wastewater-based epidemiology to monitor covid-19 outbreak: present and future diagnostic methods to be in your radar
Monitoring SARS-CoV-2 presence in wastewater has been carried out since April 2020, when the new disease COVID-19 began to spread rapidly in the Czech Republic. The aim of this study was to detect viruses in order to evaluate the possibility of using wastewater analysis as one of the tools for the...Read more
Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids
(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more
The potential impact of an implementation of microalgae-based wastewater treatment on the energy balance of a municipal WWTP in Central Europe
(Corresponding) Hasport N., Krahe D., Kuchendorf C., Theilen U., Beier S.
Topic:
Environmental biotechnology and bioenergy
The integration of a photobioreactor for wastewater treatment by microalgae is proposed as a future alternative for cost-efficient and environmentally friendly nitrogen and phosphorous removal in municipal WWTPs. The high growth rates and higher biogas yields (compared to conventional sewage sludge...Read more

Alternative wastewater treatment process with algae (AlgA) – general mathematical model and dynamic simulation
(Corresponding) Lorenz T., Behr A., Theilen U.
Topic:
Wastewater treatment
Conventional wastewater treatment systems are based on processes including the steps of pre-/ primary, sec-ondary and finally the sludge treatment. In this study a treatment step with algae as an alternative secondary treatment is supposed to improve the biological nutri-ent removal efficiency.
In...Read more
