Treatment of various agro-industrial wastewaters using electrocoagulation
Benekos A., Papadopoulos K., Triantaphyllidou I., Tekerlekopoulou A., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Greece, although not over-industrialized, is facing issues connected to pollution of its water resources, as conventional wastewater treatment methods often prove ineffective in terms of removing some pollutantssuch as suspended solids and pigments. Therefore, the need of developing efficient,...Read more
Aerobic degradation of tetramethyl ammonium hydroxide (TMAH) from effluents of semiconductor industries: kinetic studies of laboratory and pilot experiments
(Corresponding) Innocenzi V., De Michelis I., Ippolito N., Mazziotti Di Celso G., Prisciandaro M., Vegliò F.
Topic:
Wastewater treatment
Aerobic degradation of effluents contains tetramethylammonium hydroxide molecules (TMAH), coming from an electronic industry, were studied at laboratory and pilot scale. At the first, the preliminary experiments were conducted using a lab scale reactor inoculated with activated sludge coming from...Read more

Tuning of an advanced control system on a membrane process for tannery wastewater purification and chromium recovery purposes
Marchetti A., (Corresponding) Stoller M.
Topic:
Wastewater treatment
Tannery wastewater represent a hazard to the environment due to its high content of chromium. Conventional methods to purify this wastewater stream are available, but not capable to recover back chromium to the tannery process. Membranes appears to be a promising technology to achieve both targets...Read more

Quality improvement of collected rain waters by elimination of micropollutants, to sea site settlements with the use and new technologies, as suitable vegetation.
(Corresponding) Kollias P., Kollias V., Kollias S.
Topic:
Wastewater treatment
The continuous increase of water necessities to sea site settlements, created the problem to pursues the collection of rain waters in order to use them, after their treatment to succeed the necessary quality improvement. To realize that we need at first to mark the invented water sources to the...Read more
Use of the microalgae Chlorella Sorokiniana for municipal wastewater treatment: batch experiments
Kotoula D., Iliopoulou A., Irakleous-Palaiologou E., Gatidou G., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
Batch experiments were conducted in order to investigate the use of microalgae Chlorella sorokiniana for the treatment of different types of municipal wastewater (raw sewage, anaerobically treated wastewater, aerobically treated wastewater) and investigate the role of light and addition of ammonium...Read more
Feasibility of combined anaerobic-aerobic system for textile wastewater contained C. I. Acid Red 88 dye treatment: HRT effects and functional resilience
(Corresponding) Gadow S., Li Y.
Topic:
Wastewater treatment
An integrated continuous anaerobic–aerobic system has been employed as the treatment for synthetic textile wastewater contained C. I. Acid Red 88 dye. A laboratory scale of upflow anaerobic sludge bed (UASB) flowed by activated treatment was operated at hydraulic residence time (HRT) of 24, 12, 6,...Read more

Membrane Distillation Treating a Petrochemical Reverse Osmosis Concentrate
(Corresponding) Venzke C., Giacobbo A., Rodrigues M., Bernardes A.
Topic:
Wastewater treatment
This study investigated the applicability of Direct Contact Membrane Distillation (DCMD) process for the treatment of a petrochemical industry effluent, intending to recover water from the concentrate produced by reverse osmosis (RO). In DCMD, the experiments were accomplished with a feed and...Read more
Method Development for the Determination of Heavy Metals such as Copper, Iron, Manganese and Zinc in Aluminium Alloys by ICP-OES, based on wastewater analysis method
Gkogkaki V., Karageorgis A., (Corresponding) Pantazis K.
Topic:
Wastewater treatment
The determination of Heavy Metals such as Copper, Iron, Manganese and Zinc in Aluminium Alloys is usually achieved following ASTM E3061-17 Method. Alternatively, for time and cost saving, the laboratory’s ΕΝ ISO 11885:2009 method for wastewater analysis was appropriately modified producing...Read more

Optimization of decentralized treatment and sanitation of domestic wastewaters via constructed wetlands: The DOMUS_CW project
(Corresponding) Ntaikou I., Antonopoulou G., Vyrides I., Drakopoulos V., Dailianis S., Lyberatos G.
Topic:
Wastewater treatment
The DOMUS_CW project proposes the adoption of a simple, cost efficient and highly effective practice for the treatment of domestic/household wastewaters in rural areas of Balkan and Mediterranean (BalkanMed) countries, i.e. treatment via constructed wetlands (CWs). Two free surface flow CWs...Read more

Topic:
Wastewater treatment
Solar Water Disinfection Process (SODIS) is a simple technology using solar UV-A radiation (wavelength 320-400 nm) and elevated water temperature to inactivate pathogens. In the present survey, the effect of solar radiation on the disinfection of domestic secondary treated wastewater from the...Read more
