Effect of chain length on the pyrolysis of perfluorocarboxylic acids

(Corresponding) Dixon L., Stockenhuber S., Weber N., Lucas J., Grimison C., Stockenhuber M., Mackie J., (Corresponding) Kennedy E.
Topic: 
Emerging pollutants
Per- and polyfluoroalkyl substance (PFAS) are increasingly becoming the contamination issue of our time, due to their environmental persistence, bioaccumulation and mounting evidence of their toxicity. Herein we examined the pyrolytic decomposition of a series of perfluorocarboxylic acids via the...Read more

Monitoring of the main operational parameters of Aposelemis Water Treatment Plant (WTP).

(Corresponding) GYPARAKIS S., DIAMADOPOULOS E.
Topic: 
Water treatment
Rising population, increased industrial and agricultural water usage as well as climate changes have brought great challenges to water supply of adequate quality and quantity. Thus, the water treatment industry has nowadays a greater emphasis on the optimization of water treatment plants to improve...Read more

Removal of PFAS from wastewater by bio-waste adsorbent: material characterization and adsorption kinetic study

(Corresponding) Bavasso I., Bracciale M., Sbardella F., Di Palma L., Marco S.
Topic: 
Emerging pollutants
Per- and polyfluoroalkyl substances (PFAS) are considered emerging contaminants and have been increased their attention due to their distribution in water body. These compounds are acid and characterized by a thermal stability to make them resistant to degradation processes. Activities such as...Read more

Identification and Quantification of Microplastic in Sewage systems by TED-GC-MS

(Corresponding) Altmann K., Goedecke C., Bannick C., Abusafia A., Scheid C., Steinmetz H., Braun U.
Topic: 
Microplastics in the marine environment
Over the last years, the number of publications reporting the amount of microplastic (MP) all over the world increased rapidly. But harmonised sampling, sample preparation and analysis strategies are missing. Commonly used methods are very time consuming and not comparable to each other. Hence,...Read more

Employing data-driven models in the optimization of chemical usage in water treatment plants

(Corresponding) Kandris K., Romas E., Tzimas A., Gavalakis E.
Topic: 
Enviornmental data analysis and modelling
One of the most challenging tasks in potable water production is the cost-efficient and consistent operation of water treatment plants (WTPs) that treat raw water of variable quality and quantity. To increase process stability and optimize the usage of resources, two data-driven models simulated...Read more

Challenges in biological treatment plants: the approach of zero sludge waste

THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic: 
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more

Microbiological treatment of water by cold plasma at atmospheric pressure

(Corresponding) Cubas A., Machado M., Moecke E.
Topic: 
Water treatment
Ensuring the world's population access to drinking water is one of the millennium's challenges, for although our planet is made up of 70% of water, poor distribution and water quality are problems that concern world leaders, being among the objectives of development 2030 agenda set by the...Read more

Pretreatment of antibiotics-contaminated waste biological sludge by ozonation

Boševski I., (Corresponding) Kalčikova G., Derco J., Žgajnar Gotvajn A.
Topic: 
Wastewater treatment
Ozonation was studied as a pretreatment method for a waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations of over 100 mg L-1, these antibiotics were found to inhibit biogas production (up to 50%), which...Read more

Sustainable purification of greywater with green walls

(Corresponding) Boano F., Caruso A., Costamagna E., Fiore S., Demichelis F., Ridolfi L., Galvão A., Pisoeiro J., Rizzo A., Masi F.
Topic: 
Water and wastewater reuse
In this study, we describe a sustainable system for treatment and reuse of grey wastewater in urban areas through vertical green walls constructed on unused surfaces of buildings. The system integrates the benefits linked to the introduction of green spaces in urban areas with the advantages...Read more
