Catalytic reduction of Cr(VI) using recovered Silicon from end-of-life photovoltaic panels as a catalyst
Pavlopoulos C., Kyriakopoulou V., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
As installed photovoltaic panels (PVP) approach their end of life, the need for a sustainable recovery plan becomes imperative. This work aims to reuse Silicon from End-of-Life PVP as a potential catalyst/photocatalyst for wastewater treatment. PVPs were pretreated thermally (550°C for 30 min). The...Read more
Effect of current density value and current application period on the wastewater treatment performance of Electrochemically Enhanced Self-Forming Dynamic Membrane Bioreactors (e-SFDMBRs)
(Corresponding) Almalvez J., Morales-Corpuz M., Borea L., Castrogiovanni F., Napodano P., Belgiorno V., Naddeo V., Ballesteros F.
Topic:
Wastewater treatment
The use of membrane reactor in wastewater treatment gained interest for the past years due to its high-quality effluent. However, expensive membranes and high operational costs due to membrane fouling limit the wide application of this process. Research on fouling control by combining membrane use...Read more
Investigating the effect of different NaCl concentrations as draw solution used to concentrate synthetic municipal wastewater in a Forward Osmosis system
(Corresponding) Kappa S., Themeli E., Noutsopoulos C., Malamis S.
Topic:
Wastewater treatment
The main bottleneck towards resource and energy valorization of municipal wastewater is the low strength of sewage; characterized by low organic matter and nutrient concentrations. In this study, a bench scale Forward Osmosis (FO) system with a cellulose triacetate membrane (CTA) was used as a pre-...Read more

Pilot-scale membrane bioreactor for wastewater treatment using innovative encapsulated self-forming dynamic membrane
Castrogiovanni F., Borea L., HASAN S., Belgiorno V., (Corresponding) Naddeo V.
Topic:
Wastewater treatment
The use of membrane bioreactors (MBR) is a promising technique for wastewater treatment that manages to respect the restrictive limits imposed by regulations.
However, during the filtration process membranes are subject to fouling which requires additional costs for cleaning and replacing the...Read more

Wastewater Treatment and Membrane Fouling Control Using an Algae-Activated Sludge Self-Forming Dynamic Membrane Bioreactor (AAS-SFDMBR)
Corpuz M., Castrogiovanni F., Senatore V., Borea L., Buonerba A., Zarra T., Belgiorno V., Hasan S., Ballesteros F., Napodano P., (Corresponding) Naddeo V.
Topic:
Wastewater treatment
Self-forming dynamic membrane bioreactors (SFDMBRs), which utilize formed biomass layer and large pore-size mesh/ support materials instead of conventional membrane materials, have been studied for wastewater treatment applications. The consortium of algae and activated sludge bacteria has also...Read more
Anaerobic Digestion of Municipal Wastewater (MWW) in a Periodic Anaerobic Baffled Reactor (PABR)
Zarkaliou A., Kougias C., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
The scope of this work is to study the treatment of municipal wastewater in a Periodic Anaerobic Baffled Reactor (PABR). PABR is an innovative, high-rate bioreactor, designed to operate under high organic loadings. Apart from the Hydraulic Retention Time (HRT) an important operational parameter is...Read more

Nutrients recovery from anaerobic digestion effluent for the production of microalgae biomass
(Corresponding) Psachoulia P., Schortsianiti S., Dergiade I., Chatzidoukas C., Samaras P.
Topic:
Wastewater treatment
The efficient management of anaerobic digestion effluents (ADEs) from biogas plants has raised increasing environmental concerns, as a result of their high content in nutrients, mostly in the form of NH4- and PO4-. Their discharge to farmlands is restricted due to irrigation guidelines, while...Read more
Application of quorum quenching to improve performance of membrane bioreactors: A comprehensive mini-review
(Corresponding) Banti D., Kampouris I., Yiangou M., (Corresponding) Samaras P.
Topic:
Wastewater treatment
Membrane bioreactors (MBRs) have been widely used for wastewater treatment, presenting however a major disadvantage, the membrane fouling problem. The sludge microorganisms produce soluble microbial products (SMP) and extracellular polymeric substances (EPS) that lead to a formation of a sticky...Read more

Comparison of the continuous fermentative hydrogen production efficiency from cheese whey in suspended and attached-biomass growth systems
ALEXANDROPOULOU M., LYBERATOS G., (Corresponding) ANTONOPOULOU G.
Topic:
Wastewater treatment
In the present study, comparison of dark fermentation (DF) efficiency from cheese whey (CW) in an anaerobic UpFlow Column Reactor (AUFCR), filled with a support material for biomass attachment and a Continuous Stirred Tank reactor (CSTR), was assessed. The process efficiency and stability as well...Read more

Seafood wastes as an attractive biosorbent: Chitin-based shrimp shells
Bahadır T., Gök G., (Corresponding) Çelebi H., Şimşek İ., Gök O.
Topic:
Wastewater treatment
In recent years, water quality deteriorated with Zn (II) ions has started to take place among the important environmental problems. Zn (II) is a primary type of toxic and bioaccumulative pollutant commonly found in industrial wastewater. Biosorption is the most practical method in the treatment of...Read more
