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

Suspected-target screening for the assessment of pollutants in sewage sludge and assessment of their environmental risk
(Corresponding) Álvarez-Ruiz R., Cuñat A., Picó Y.
Topic:
Wastewater treatment
Wastewater generated by human activities contains different organic pollutants from anthropogenic origin. During its depuration in the wastewater treatment plants (WWTPs) sewage sludge is generated, which also contains these pollutants. While water influents and effluents of WWTPs are widely...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

Photocatalytic Removal of Pesticides Present in Agro-industrial Water Effluents
Arfanis M., Theodorakopoulos G., Anagnostopoulos C., Georgaki I., Liappis K., Romanos G., Markellou E., (Corresponding) Falaras P.
Topic:
Wastewater treatment
Pesticide residues accumulated in agricultural wastewaters constitute a potential risk for the environment and the human health. Hence, focused actions for their elimination are of high priority for both the industry and national authorities. This work evaluates the effectiveness of the...Read more
